Patient's Query

Hi doctor,

My wife sometimes has a high heart beat more than 200 times in a minute. Gone through ECG and Holter test, but could not find why it is happening. She is 40 and hypothyroid patient and taking Thyroxine 50 mg. Please suggest any treatment for that.

Hello,

Welcome to icliniq.com.

Please show me ECG (electrocardiogram) and Holter so that I may diagnose what is rhythm, and prescribe management plan. She is taking Thyroxine which may also cause sometimes fast heart rate. Do thyroid profile, if not done recently, and send me results. Finally, try to reduce weight. Obesity is a field in which different diseases grow including cardiovascular, cerebrovascular and sugar.

The Probable causes

The probable causes are thyroxine overdose, anxiety, and atrial fibrillation.

Investigations to be done

Do TSH (thyroid stimulating hormone), T3 (triiodothyronine), and free T4 (thyroxine).

Same symptoms don't mean you have the same problem. Consult a doctor now!
