[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. But don't worry.I'll try to explain you something and give you some advises. You might experience fast, and strong heart beats for different reasons. It may be a simple sinus tachycardia. This mean that your heart beats over 100 beats for minute. Its normal range in resting situation is between 60-100 beat for minute. This might happen from different reasons from simple emotional stores to different pathologies like anemia, hyperthyroidism etc. You may feel strong heart beats because of extrasistoles.These is electrical impulses that generates from different parts of the heart different from that of a normal sinus rhythm. This houses an ectopic, escaped beat and you feel like a beat is skipping, and the other one is stronger causing difficulties in breathing fully and sometimes a cough. The extrasistolic beats might happen for the same reasons as sinus tachycardia. Sometimes in young ages or in stressed periods these are quite normal, and they come ang go. But if your heart beats very fast suddenly and in a chaotic, irregular way it might be what we call an atrial fibrillation. This is an arrhythmia when the heart doesn't beat in a normal sinus rhythm. You might experience paroxysmal episodes when your heart jumps from normal rhythm to fibrillation and vise- versa. So, if I was your treating doctor I will recommend you to make some simple examinations like a blood analysis to exclude anemia or hypothyroidism, an electrocardiogram,echocardiography and of course a holder monitoring for 24-48 hours. This will tell as your rhythm tendency. You have nothing to worry, but I will recommend this check up if these symptoms begin to interfere with your normal healthy live. At mean time avoid coffee and caffeine products because they rise your heart frequency or extra systoles. Hope I was helpful. Wish you good health. Best regards.
