Patient's Query

Hello doctor,

I use a Holter monitor test for my palpitations. I use them when I lay down, especially on the left side, but they disappear after some time. My physician told me it could be mitral valve prolapse and is not something to worry about. I also underwent ECHO, which was normal, but the Holter monitor test showed the longest QTc being 512. So the physician advised doing ECG, which was also normal. I never had syncope, shortness of breath, or a family history of sudden death or seizures. Should I be worried? Kindly help.

Hello,

Welcome to icliniq.com.

Thank you for your query. I reviewed your query (attachment removed to protect the patient's identity). Do not worry about QT, as I found QTc to be normal in your ECG (electrocardiography). However, the Holter monitor test shows a lot of premature complexes. So I suggest you follow the instructions mentioned below. Get serum electrolytes checked - Sodium, Potassium, Magnesium, and Calcium. Check (Hb) hemoglobin level. Check vitamin D levels. Also, to rule out any coronary artery disease, get a TMT (treadmill test) test done whenever possible. I hope this has helped you. Thank you.

Patient's Query

Hello,

Thank you for your reply. Here are the findings of my reports. My hemoglobin is fine, but the vitamin D test showed a deficiency (16.20 ng/mL), which should be above 20 ng/mL. Should I start vitamin D supplements? I have attached my Echo reports. And now, I will go for the electrolytes test and then TMT. Kindly help.

Hello,

Welcome back to icliniq.com.

Your Echo (echocardiogram) is good (attachment removed to protect the patient's identity), and prolapse is there but no good insufficiency. Also, I suggest you to take vitamin D supplements as it is also one of the causes of palpitations, and long-term deficiency can lead to cardiomyopathy. So I suggest you to take vitamin D3 60000 IU (sachet or capsule) once a week for ten weeks. Followed by the same dose once per month for a year. Kindly consult a specialist, talk to them and take the medications with their consent. I hope this has helped you. Thank you.
