Can a Zio Monitor Identify POTS?
Summary: I used a Zio monitor for a week that ruled out POTS, yet I'm exhibiting symptoms others believe align with it. My cardiologist indicated the monitor excludes POTS, but numerous opinions suggest otherwise. Who should I believe? Hey there! I'm a 23-year-old female dealing with various health issues, none of which are heart-related. Last year, I experienced severe anxiety that led me to the ER, mistakenly thinking I was having heart palpitations, but it only turned out to be an anxiety attack paired with a minor sinus arrhythmia. As a result, I underwent a 7-day Zio monitor test, and the results primarily came back within normal limits, with only minor irregularities that my healthcare provider deemed very common—such as some trivial valve issues that he assured me were not concerning right now, perhaps only as I grow older. After discussing the findings, I inquired about testing for POTS because of the multiple symptoms I had. The cardiologist stated that the monitor's results had ruled out POTS completely and advised against any further testing. However, in my conversations with other doctors and my extensive research, I've found that a Zio monitor typically does not detect POTS and that diagnosis usually requires a tilt table test or alternative evaluations. I often feel dizzy when I stand, regardless of how I change positions, and I frequently experience exhaustion, along with near-fainting spells. These signs, along with a family history of similar conditions, make me wonder about my diagnosis. While I understand that the cardiologist is specialized in this field, the healthcare facility in my region has a notorious reputation for poor service and I’ve had several frustrating experiences with this medical group. What should I believe?

Understanding your concerns regarding the Zio monitor and the possibility of Postural Orthostatic Tachycardia Syndrome (POTS) is important, especially given your symptoms of dizziness, exhaustion, and near-fainting spells. Let's break this down.
Key Points:
- A Zio monitor primarily tracks heart rhythm and may not provide sufficient information to rule out POTS.
- Your symptoms, such as dizziness when standing and fatigue, align with POTS, but additional tests may be necessary for a definitive diagnosis.
- Consider seeking further evaluation either through a different healthcare provider or through specialized testing.
Explanation:
The Zio monitor is designed to detect arrhythmias and assess heart function, but it does not directly test for POTS. POTS is primarily characterized by an abnormal increase in heart rate upon standing and is typically assessed through tilt table tests or active stand tests. Your symptoms, especially given the dizziness and near-fainting episodes when transitioning to an upright position, should be taken seriously, especially since they have a familial link.
It’s understandable to feel frustrated with the current healthcare system, especially if previous experiences have been negative. Given that your cardiologist has indicated that POTS is ruled out based on the Zio monitor, but you still experience concerning symptoms, it's important to advocate for your health.
Next Steps:
-
Symptom Diary: Start keeping track of your symptoms, noting when they occur, their duration, and any possible triggers. This information will be useful for any future medical consultations.
-
Seek a Second Opinion: If you're unsure or uncomfortable with your current cardiologist's conclusions, consider seeking a second opinion from another cardiologist or a specialist in autonomic disorders. Look for one with experience in POTS.
-
Request Comprehensive Testing: If you do see another healthcare provider, discuss your symptoms in detail and ask about the possibility of a tilt table test or active stand tests to assess for POTS more conclusively.
-
Hydration and Support: In the meantime, remain hydrated, as dehydration can exacerbate POTS symptoms. Some patients find increased salt intake helpful, but always check with a healthcare provider before making dietary adjustments.
-
Lifestyle Adjustments: Consider gradual changes in your activity levels, and if you feel faint, don’t rush when moving from a seated or lying position to standing.
-
Join Support Groups: Connecting with others who have similar symptoms can provide emotional support and practical advice. Look for groups focused on POTS or autonomic dysfunction.
Remember, you deserve to have your symptoms taken seriously, and persistence in seeking answers is key. Let me know if you need further clarification on any specific points!

Eight Years of Persistent ‘Hunger’—Is It a Functional Gut Disorder?
Greetings everyone, I’m a 28-year-old woman standing at 5 feet 4 inches, and for nearly eight years, I have struggled with a constant, hollow sensation in my upper abdomen that resembles hunger. Here are some key points about my experience: - This sensation arises between meals or soon after I have eaten. - It gets momentarily better after eating but eventually returns. - Though it feels like hunger, I know it's not genuine hunger. - Mornings are especially tough as the sensation intensifies. I maintain a regular meal schedule and consume enough calories without any restrictions. Currently, I find it difficult to trust my hunger cues, so I'm tracking my calorie intake. I do not take any medications and have previously used proton pump inhibitors without any noticeable improvement. Additionally, I neither smoke nor consume alcohol. Visits to my general practitioner have yielded no definitive diagnosis, with much of the feedback being centered on dietary adjustments. I am currently facing a waiting period of approximately eight months for a gastroscopy. Strangely, I also notice that I feel particularly weak during my workouts, despite my calorie intake being sufficient. Has anyone else faced a similar long-term issue? Did you find it to be functional dyspepsia, gastritis, visceral hypersensitivity, or something entirely different? Were you able to obtain assistance through a gastroenterologist, a dietitian, or therapy? Thanks for your insights!
Understanding My Lack of Appetite
I’m a 14-year-old girl about to turn 15, standing at 155 cm (5' 1'') and weighing around 53-54 kg. My exact weight remains unclear since I am battling anorexia and have been advised against using the scale. I am currently on a regimen of antidepressants (150mg of semonic daily) and antipsychotics (15mg of olanzapine). Along with my eating disorder, I've struggled with self-harm and have been diagnosed with a conduct disorder (though I'm unsure if that is the correct term in English as I'm receiving treatment in Spain). In September, coinciding with the start of the school year, I experienced a relapse regarding my eating disorder. This phase lasted a few weeks until I transitioned to homeschooling. Initially, recovery felt manageable; I experienced satiety quickly, and I was relieved to allow myself to eat once more. However, I’ve noticed a significant decrease in my appetite. I rarely feel hungry, and even when I do, it doesn't seem to bother me. I’ve lost the desire for typical meals, though I still find myself yearning for snacks, particularly sweets or salty options, which are much more appealing and easier to consume. Foods like rice are particularly challenging; I have to push myself to continue eating them because they don't excite me at all. I’m uncertain if this change is due to some underlying issue or merely stress, although I don't currently feel stressed. Perhaps my lack of physical activity contributes to my diminished appetite, as I haven't been particularly active and might not need as much food as others. It’s also worth noting that I haven’t grown taller for about a year or two, remaining at 5' 1''. This situation wouldn’t be as concerning if I weren’t dealing with anorexia, allowing me to simply eat less. Yet, given my background, I require supervision at mealtimes, which complicates my relationship with food. Whenever I lack the desire to eat, those around me jump to the conclusion that I am relapsing, which I am not. I enjoy food tremendously, especially sweets, and I snack throughout the day. It’s just the full meals that elude my cravings completely.
Rapid Heart Rate During Illness
A 27-year-old male, standing at 6 feet 3 inches tall and weighing 275 pounds, presents as non-smoking with a medical regimen including buspirone, sertraline, and Nexium. He does not consume alcohol or use illicit drugs. His medical background highlights anxiety and a previously noted Wolff-Parkinson-White (WPW) pattern observed on an ECG in 2023, without any prior ablation or recorded arrhythmias. On February 5th, I visited the emergency room after experiencing a sudden and alarming increase in my resting heart rate to approximately 130 beats per minute while at home. This spike was particularly distressing given my history of chronic anxiety. Reflecting on the earlier part of the day, I recall experiencing mild body aches, a cough, and a sensation akin to a low-grade fever, which now appear to have been early signs indicating I was becoming ill. Once at the emergency room, the medical team administered 10 mg of propranolol, resulting in a gradual decrease in my heart rate from 130 to the mid to upper 90s over a span of about one hour and 45 minutes. The ECG revealed only sinus tachycardia, and notably, the doctor informed me that the WPW pattern from 2023 was no longer evident. All laboratory tests returned normal results with standard electrolyte levels, kidney function (eGFR at 108), and a complete blood count showing only a typical stress response characterized by elevated neutrophils and reduced lymphocytes, alongside normal urine tests. There were no indications of dehydration, infection, thyroid irregularities, or arrhythmia. After returning home, it became clear that I was battling a viral infection. I experienced chills, extensive body aches, and fever peaking at 101.8°F, as well as a cough with medium brown mucus (not excessively dark or bright red). I have not experienced shortness of breath or wheezing at rest. Notably, my heart rate has paralleled my fever. When my fever ranges between 101°F and 102°F, my resting heart rate typically aligns between 105 and 125 beats per minute. Conversely, as my fever declines into the 99°F range, my heart rate drops to the 80s and 90s. Under normal circumstances, my resting heart rate hovers around 60 beats per minute. Currently, I am measuring a temperature of approximately 100.6°F to 100.8°F, with a heart rate around 110 to 115 beats per minute. About an hour ago, I took Tylenol, and am staying hydrated and resting. The only discomfort I feel is due to persistent coughing. I have a few inquiries: - Is this heart rate fluctuation typical during a viral infection accompanied by fever? - Should I expect to see an elevated heart rate persist even during sleep when my fever is elevated? - Is there any cause for concern regarding my previous WPW even though the recent ECG indicates that pattern is no longer present? Thank you for your assistance.
Is Experiencing Fatigue Common While Using Antibiotics for a UTI?
As a 20-year-old female undergoing treatment with ciprofloxacin, I've noticed a troubling pattern. On the third day of my antibiotic regimen, I've begun to experience the return of some symptoms.

Insights on Meningocele and Related Symptoms
I would appreciate your thoughts on my situation—thank you! In 2019, during a meningitis incident, a right petrous apex meningocele was discovered when the white blood cell count in my cerebrospinal fluid (CSF) exceeded 7100. That's an astonishing figure! Unfortunately, doctors were unable to determine the exact type of meningitis, as bacterial cultures failed to grow, and the WBC count didn’t correspond with typical viral or aseptic markers. A specialist in infectious diseases expressed skepticism about a meningitis diagnosis, noting that my cognitive clarity remained sharp throughout the ordeal. I'll provide the latest MRI and CT findings as well as significant images in the comments section. The meningocele seems to be progressing, evidenced by bone erosion. Prior imaging indicated persistent fluid in the right mastoid air cells, which is no longer observed in recent scans. I have undergone numerous lumbar punctures; however, they struggled to record an opening pressure due to unusually low levels. During the last attempt, they could only extract about half the necessary CSF since there simply wasn’t enough present, even after three separate punctures and being positioned on a tilt table. I experience a range of symptoms, including changes in vision, pulsatile tinnitus, issues with posture, and episodes of tachycardia. The most intense symptom, however, is trigeminal neuralgia, which can lead to severe attacks lasting over 40 minutes. Based on my symptoms and various self-management strategies, I suspect my condition might fluctuate between low and high pressure. For relief, I either lie flat and increase my caffeine intake or sleep at an angle while consuming diuretic tea as if my well-being depended on it. Since receiving this diagnosis five years ago, I have also developed degeneration in my cervical spine, including joint slippage and bone spurs, along with right TMJ degeneration and thoracolumbar scoliosis. Although I’m not sure if these are all connected, I think it's worth mentioning. Thank you for reading! **CT Findings:** **Right Side:** - **External Auditory Canal:** Open without any visible mass or abnormal bone growth. - **Middle Ear and Ossicles:** Normal tympanic membrane; the middle ear and Prussak's space are clear. The scutum and ossicles show no signs of erosion, and the facial nerve appears unremarkable. - **Mastoids:** Clear. Stable lucency and thinning of the petrous apex bone, reflecting CSF signal intensity and continuity with the right Meckel's cave, indicating the likelihood of a Meckel’s cave cephalocele. - **Cochlea and Vestibular Apparatus:** Normal structure and function, with no adjacent bone erosion or signs of semicircular canal dehiscence or vestibular aqueduct enlargement. **Left Side:** - **External Auditory Canal:** Open without any visible mass or abnormal bone growth. - **Middle Ear and Ossicles:** Normal tympanic membrane; the middle ear and Prussak's space are clear. The scutum and ossicles show no signs of erosion, and the facial nerve appears unremarkable. - **Mastoids:** Clear. - **Cochlea and Vestibular Apparatus:** Normal structure and function, with no adjacent bone erosion or signs of semicircular canal dehiscence or vestibular aqueduct enlargement. **Other Findings:** - Scalloped lucencies in the right TMJ articular eminence indicate small areas of dehiscence, potentially due to a combination of degenerative joint disease and arachnoid granulations. **MRI Findings:** There is no evidence of acute or subacute ischemia or hemorrhage, nor is there any mass effect or midline shift. No signs of cortical atrophy or ventricular enlargement are present, and there are no suspicious marrow lesions. A prominent fluid signal near the right petrous apex, related to the right Meckel's cave, measures at least 1.8 cm diameter. It shows no complex imaging characteristics, maintaining discrete margins without enhancement or significant internal structure. Postcontrast imaging reveals no abnormal enhancement in the brain or meninges, with major draining veins appearing patent. Bilateral internal auditory canals are unremarkable, and there is no evidence of white matter disease or atrophy in the midbrain. The craniocervical junction and upper cervical cord are also normal. **Impression:** 1. A simple cystic lesion measuring 1.8 cm at the right petrous apex adjacent to the fifth cranial nerve root/Meckel's cave was identified, correlating with the history of right trigeminal neuralgia. Follow-up imaging should include dedicated internal auditory canal studies. If previous CT temporal bone imaging becomes available, adjustments can be made accordingly. 2. The remaining brain and orbits appear normal, and postcontrast imaging results are unremarkable.
