What Causes Recurring Fast Beating Heart?

For the past 2 years I ve been having this fast beating heart. It beats even when I am sitting or laying down. And it s starting to interfere with my life because I get so tired that I can t do anything. Sometimes it beats so fast that it causes me to have a panic attack. So I was wondering what it may be and how I can fix it. Plus I have heard of these things that are called Beta Blockers, I was wondering if they could be used for my condition. And I m 15 by the way, so it shouldn t be any severe heart problems or anything.

Hello,

You need to undergo 12 lead ECG with a rhythm strip, to know the nature of Tachycardia (Sinus Tachycardia or otherwise).

You also need to undergo Thyroid function test (free T3,free T4 & TSH) to exclude hyperthyroidism which can cause resting tachycardia (for which beta blocker is the drug of choice).

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
