Can a Zio Monitor Identify POTS?

8/1/2025, 11:50:21 PMMale25-34

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:

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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!

Seeking Guidance on Blood Sugar Levels

Hello everyone, I’m a 24-year-old man and I could really use some advice regarding my blood sugar measurements. Recently, I've been using a glucometer to track my glucose levels, and I’m feeling quite anxious about it. This morning, I checked my levels after fasting overnight and they read 110 mg/dL. It took longer than expected for the results to display because I was quite nervous. After about seven minutes, I decided to test again and this time my level was 96 mg/dL. I can’t help but worry that I might be entering the realm of prediabetes. Yesterday, I tested my glucose two hours post a meal consisting of pizza and hibiscus juice, and the reading was 118 mg/dL, which seems somewhat elevated but not excessively high. I’m reaching out to see if anyone has insights into how glucometers work, especially regarding the fluctuations in readings. Can blood sugar levels drop so significantly in just a matter of minutes? Also, I’ve been feeling completely fine without any noticeable symptoms. Any help or information would be greatly appreciated!

Advice Wanted on Iron Deficiency Concerns

At 19 years old, I'm currently not on any medications, apart from a herbal syrup intended to assist with regulating my menstrual cycle. Even though it may not be directly related, I should mention that I have polycystic ovary syndrome (PCOS), likely of the adrenal variety, and I’ve been dealing with gastrointestinal issues for several years. I underwent a blood test recently, and the results indicated that my serum iron and transferrin saturation are below normal, while my UIBC is elevated and TIBC is within a normal range. I’m uncertain about how to make sense of these results, but I have been experiencing symptoms indicative of iron deficiency for quite a long time, which prompted me to seek a professional opinion. These symptoms include: - Persistent fatigue - Frequent bruising - Pale complexion and lips - A generally unhealthy appearance - Poor blood circulation - Occasional dizziness and visual disturbances whenever I stand up after sitting or lying down. Additionally, my vitamin D levels are quite low at 17 ng/mL, which may be exacerbating some of these symptoms. In response, I have begun taking 6000 IU of vitamin D in syrup, once weekly, under guidance for a duration of 3 to 4 months. Regarding iron intake, several family members have suffered from iron deficiency as well and have successfully managed it with supplements. However, due to my digestive issues, I’ve been advised against taking iron tablets, as they could aggravate my stomach problems. My diet is fairly nutritious, as I consume a variety of fibrous foods and focus on a vegetarian menu, preparing meals at home almost exclusively. Occasionally, I include beetroots, pomegranates, and other iron-rich foods. Nevertheless, I am unsure of further steps to enhance my iron levels. The ongoing symptoms are quite bothersome and negatively affect my daily life, so any suggestions would be greatly appreciated.

Understanding Elevated Ketones in Relation to Kidney Stones

Age 37, female. I recently visited urgent care where I was diagnosed with a kidney stone purely based on my symptoms, without any imaging being performed. During the evaluation, the physician noted abnormalities in my ketones, protein levels, and urobilin, along with a slight presence of blood. My urine's specific gravity was measured at 1.025. While I acknowledge that my hydration levels could be better, I have consumed enough fluids today to urinate several times, and I had carbohydrates earlier in the day, which indicates I haven't been fasting at all. The doctor didn’t seem concerned about the elevated ketone levels, yet it struck me as peculiar because I didn't exhibit such ketones when I was hospitalized due to severe dehydration in the past. I would appreciate any insights or explanations regarding this situation. Thank you!

M30 (Thirties) - Awaiting Guidance on MRI Results

I just received my MRI results and now I face a waiting period of two weeks before discussing them with my physician. I would appreciate your insights into their significance and the possible treatments that could be recommended, if necessary. To summarize my situation, I was involved in a car accident around two months ago, which resulted in a mild neck sprain, often described as whiplash. From my understanding of the results, it seems that any noted issues are likely attributed to normal wear and tear that occurs naturally as we age. Nevertheless, if there are indications within the report that might link back to the car accident, this information would greatly benefit my situation. Additionally, I would like to know your opinion on what treatment options may be advisable at this stage, if any are deemed necessary. Thank you for your assistance!

Digestive Concerns in a Three-Month-Old

Subject: Uncovered Digestive Challenges in My Infancy Stage Summary of Baby's Details: - Age: 3 months - Gender: Female - Height: 21.5 inches - Weight: Approximately 10 pounds - Ethnicity: Caucasian Concern Duration: Roughly 2.5 months Current Location: Michigan, USA Around the time my little one was four weeks old, she began to face considerable digestive hurdles. We initially started with breastfeeding, and at first, we noticed what we believed could be severe gas and colic. To address these issues, we administered Mylicon at home. When that proved ineffective, we reached out to her pediatrician, who later examined one of her diapers and discovered traces of blood in her stool. In response, she suggested that I remove dairy from my diet if I wished to persist with breastfeeding or to introduce Nutramigen. We immediately transitioned her to Nutramigen, hoping for her to find some respite while I eliminated dairy from my meals. This lasted around two weeks. Upon attempting to reintroduce my breast milk, she rejected it both from the breast and the bottle, which marked the end of our breastfeeding experience. Despite being on the hypoallergenic formula, her condition deteriorated – she began projectile vomiting, incessantly crying as if in pain, and never appeared satisfied post-feeding. Consequently, we were referred for an urgent abdominal ultrasound to exclude the possibility of pyloric stenosis, which thankfully was ruled out. We proceeded with treatment for Cow's Milk Protein Allergy (CMPA) and reflux, which involved administering famotidine and switching her to an amino acid-based formula. This change has notably improved her condition, but I still observe discomfort surrounding her feeding and digestion – she cries following meals, tenses her body and arches her back, strains and screams during bowel movements, and frequently spits up even hours after eating. Recently, I stumbled upon the results from the ultrasound in her MyChart account, which I had neglected to check since the pediatrician informed us of the results by phone. Out of curiosity, I reviewed the report, which stated, "No sonographic evidence of pyloric muscular thickening. Only trace gastric contents are seen passing through the pylorus. Alternative etiologies for gastric distention should be considered." Now I am left wondering whether I should push for further investigation into the gastric distention or if CMPA might be the underlying cause. Would it be prudent to ask for a referral to a gastrointestinal specialist? I am anxious about potentially overlooking something critical, yet I do not want to subject her to unnecessary tests fueled by my worries. Thank you for taking the time to read this lengthy correspondence. I aimed to provide you with all pertinent information regarding her situation.
