Panic Attacks Answer A25084

Welcome to the ehealthforum and I am really glad to help you out. Your concern is regarding the tachycardia or fast heart beat and feeling sick and weak. Taken when at rest, a normal adult's pulse can be anywhere from 60 to 100 beats per minute.

Anything over 100 is technically defined as a tachycardia. Tachycardia at rest can be found in anxiety, stress, nervousness, panic attack, after a large meal, exercise,high or low BP, paroxysmal supraventricular tachycardia, heart disorders, hyperthyroidism and anemia. Other possibilities for your symptoms are neuropathic postural tachycardial syndrome(also called hyperadrenergic orthostatic tachycardia, or postural orthostatic tachycardia (POTS) and cardiac and neurological causes.

I feel that if you have repeat episode of such kind, then you should consult a cardiologist and get ECG and stress echo done.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
