Heart Monitor Findings - Over 2,100 Tachycardia Episodes
Patient Profile: 16 years old, 5’3”, weighing 105 lbs, non-smoker, non-drinker, and no ongoing medication. I have a slight mitral valve prolapse. Currently, I am undergoing evaluation for potential postural orthostatic tachycardia syndrome (POTS). Two healthcare professionals have suggested this diagnosis, prompting a cardiologist to conduct a 14-day heart monitoring assessment. According to the results, everything appeared normal, with no indication of elevated heart rates, which was a specific inquiry we made. Remarkably, I experienced numerous incidents of fainting during the monitoring timeframe. While I cannot present all the patient event notifications due to the extensive nature of the report—totalling 76 pages—this primary results page highlights more than 2,100 occurrences of tachycardia. This discrepancy raises questions about whether further investigation into POTS is warranted. Unfortunately, my cardiologist declined to conduct additional tests and was hesitant to schedule a follow-up appointment to discuss the findings, as well as reluctant to provide us with a copy of the results. A routine pediatric consultation has been arranged for the end of July with a physician specializing in hematology.

It sounds like you're dealing with a complex and concerning situation regarding your heart health and symptoms. It's understandable to be frustrated and confused by the findings and the response from your healthcare providers. Here's how to approach this:
Key Points:
- Understanding the Heart Monitor Results: You have a significant number of tachycardia episodes, coupled with fainting spells, which are noteworthy findings, especially as you are being evaluated for POTS.
- Seeking Clarity on Diagnosis: Your heart monitor results do not align neatly with your symptoms, and there may still be underlying issues that need addressing, particularly regarding POTS.
Explanation:
Tachycardia is when your heart beats faster than normal. It can happen for many reasons, including anxiety, dehydration, or as part of a condition like POTS where the autonomic nervous system misregulates heart function, particularly upon standing or changing posture. Fainting can result from low blood flow to the brain, which is common in POTS. Your symptoms are important and deserve further exploration, especially since your symptoms weren't clearly linked to the findings from the monitoring.
Actionable Next Steps:
-
Document Your Symptoms: Keep a detailed diary of your symptoms, noting when your fainting episodes occur and any other related symptoms (like dizziness, heart palpitations, or fatigue). This documentation can be valuable for any future consultations.
-
Prepare for Your Pediatric Appointment: Before your upcoming pediatric appointment with the hematologist, consider compiling your heart monitor results, symptoms diary, and a list of questions or concerns. Ask for clarification on why further tests may not be necessary, and advocate for your health by expressing your concerns directly.
-
Second Opinion: If you still feel uncertain about your diagnosis or the next steps, consider seeking a second opinion from another cardiologist or a specialist in autonomic disorders. It's important that you feel confident in your care and understand your health situation.
-
Lifestyle Modifications: While you're awaiting further evaluation, make some lifestyle adjustments that can help manage symptoms:
- Stay well-hydrated: Aim for 2-3 liters of water per day, if tolerated.
- Increase salt intake: Under your doctor’s guidance, adding salt can help expand blood volume.
- Wear compression garments: These can help with circulation and reduce the chances of fainting.
- Avoid triggers: Note any activities or positions that exacerbate your symptoms and try to modify those.
-
Stay Informed: Learn more about POTS and its management through reputable sources. Understanding your condition can empower you to engage effectively with professionals treating you.
It's clear you are advocating for your health, which is vital. Reach out if you have more questions or if you need additional support.

Persistent Redness and Numbness in Left Foot
Age: 22, Weight: 117 kg Not currently prescribed any medications. No smoking habits, consumes alcohol moderately, and uses recreational drugs occasionally. Over the past couple of months, I have experienced a developing sensation of numbness on the outer aspect of my left foot. This was soon followed by the emergence of a small, firm bony lump beneath the skin, which is not replicated on my right foot. Additionally, I've observed a patch of redness that has become a consistent feature, slightly smaller in size than the numb area. To my knowledge, there hasn't been any recent injury to the foot. I would estimate that these symptoms have persisted for around two months now. **I seek insights from medical professionals regarding A) the possible causes of this condition, and B) whether I should consult a healthcare provider in my vicinity for further evaluation. The redness seen on the top of my foot is a result of scratching an itch in that area. While this might be a related issue, I also spent some time at the beach just hours before I posted this inquiry.
Enigmatic Back Discomfort
Twelve days ago, I, a 68-year-old woman, started experiencing what I initially thought was a muscle strain in my back, despite having engaged in no heavy lifting or intense physical activity. The discomfort has escalated significantly, reaching a level of pain that fluctuates between 7 and 9, making it unbearable. Interestingly, just five days ago, my 25-year-old daughter began suffering from the same back pain. She’s known for never taking time off work due to illness, yet she has been unable to return for the past five days. Both of us have been grappling with an overwhelming desire for more sleep, as this type of pain is notably exhausting. Since these symptoms appeared, we have reached out to multiple healthcare providers, yet have received no relief or satisfactory answers: a massage therapist, a chiropractor, a virtual nurse practitioner, an emergency room visit with X-rays and lab tests, and a general practitioner. The lab results and imaging have ruled out kidney stones, gallbladder issues, infections, and bowel blockages, and thankfully, we haven’t had any fever. Despite our efforts, including over-the-counter pain medications, prescribed muscle relaxants, topical pain relief creams, dietary supplements, bed rest, and various home remedies like heat and ice therapy, Epsom salt baths, and supportive aids for the back, nothing has improved our condition. Considering the differences in our ages and lifestyle, I find myself wondering if this could be an undetected virus. Our busy schedules seldom overlap, and we rarely share meals, which might contribute to this odd situation. Has anyone come across a similar experience or information related to these symptoms? I’m feeling quite lost and overwhelmed. Is this potentially another strain of COVID-19? I would greatly appreciate any insights or recommendations on how to address this distressing issue.
Am I Experiencing a Reinfection After Recovering from a Cold?
I’m a 36-year-old male of South Asian descent, weighing 165 lbs and standing at 5'8". It has been more than two weeks since I initially caught a head cold, with my mild fever (at 37.4°C) subsiding two Saturdays ago. The only lingering issue I have is a persistent nasal congestion, which makes my voice sound congested; I also experience a very slight cough that produces little to no mucus. Overall, I feel physically well at this point. However, yesterday I encountered a severe headache caused by sinus pressure, which was so intense that it affected my upper left molars. Each night, I’ve been using OMNARIS nasal spray, along with an inhaler containing salbutamol and fluticasone. Additionally, I perform saline nasal rinses with several neti pots. My primary care physician prescribes these medications whenever I deal with respiratory issues due to my medical history, which includes a case of pneumonia about six years ago. In the last couple of nights, I have observed some unusual discharge from my nose after doing the saline rinse, and the color of it has raised some concerns about a potential reinfection. The only recent exposure I can think of that might have put me at risk was last weekend, when I went swimming in a lake and participated in some paddleboarding along a creek. Despite the humid 37°C heatwave, I felt strong and well enough to engage in those activities. I appreciate any insights you may have on this situation. Thank you!
Significant Swelling in Calves and Feet
Greetings, I'm a 31-year-old woman experiencing considerable swelling issues. It all began in my left ankle last August, shortly spreading to both ankles. For the past four months, I've faced extreme swelling in my calves, ankles, and feet, and the last three weeks have been particularly challenging with a level of swelling that refuses to subside. The tightness in my skin has made it nearly impossible to walk comfortably. I consulted my physician last week, who prescribed Lasix and requested some lab tests. The medication has been effective in reducing my swelling, but the lab results indicated elevated RH Factor and anti-MCV levels. Thus far, I haven’t experienced any other symptoms typically associated with rheumatoid arthritis, as far as I know. Currently, the symptoms I’m dealing with include significant swelling, abdominal bloating, occasional shortness of breath, headaches, and infrequent tingling in my right arm and left foot. My doctor has suggested a series of further examinations, including a brain MRI, an ultrasound of my legs, and consultations with both a cardiologist and a rheumatologist. Generally, I have maintained good health and seldom fall ill, which leaves me puzzled about the cause of my swelling. I’m reaching out to see if anyone has any insights or suggestions regarding my condition. I understand I will receive more information in due time, but my first appointment is still weeks away, and I am feeling quite anxious.
Incident of Near-Drowning
Earlier this evening, approximately at 6:45 PM, my three-year-old daughter experienced a near-drowning situation. I had momentarily turned my attention to a conversation for just about 15 seconds. During that brief absence, I cannot determine exactly how long she had been struggling, but I know she was not entirely submerged the whole time, as she managed to get some air in between. As soon as I realized what was happening, I quickly rescued her. She was coughing and crying due to her distress. I comforted her by holding her close and gently patting her back. After a couple of minutes, she threw up. Fortunately, she has been doing well since that incident. However, after learning more about the risks associated with "secondary drowning," I am uncertain whether I should take her to the emergency room considering the nature of the incident, the immediate symptoms, and the vomiting—a combination of factors that worries me—or if I should simply keep an eye on her at home since she shows no current symptoms. I appreciate any advice you can offer.
