I have been having these fast beating heart episodes since i was about 15...  I will be either sitting down, laying in bed or in the shower and my heart will just start beating really fast. I believe i have Paroxysmal Supraventricular Tachycardia. If so is it dangerous to have?
Hello and thank you for using Healthcare magic. I have read your question very carefully. Looks like you are feeling palpitations which are fast regular or irregular heart beats. There are many causes of these symptoms. I would recommend you to do a test, a 24 or 48 hours Holder ECG which records ECG for 24 to 48 hours, and hopefully I would record a tachycardia attack. In that way you can find out which type of arrhythmia it is and get medication for your condition. Also, if you can obtain an ECG during your heartbeats it would be very helpful to diagnose you. The causes of fast heartbeats are many, ranging from simple Ventricular Extrasystoles to Supraventricular Parodistic Tachycardia. Have a wonderful time ahead. Hope I answered all of your questions. Let me know if you have any further clinical concerns or doubts. I will be more than happy to get back to you in no time. If satisfied here, please give a generous five-star rating and don't forget to close the discussion.
