Thanks for writing to us.
Do you noticed them by chance or you have any symptoms?i hope you never had blackout/ loss of consciousness/ shortness of breath
or unexplained fall. if these symptoms are there , please see your cardiologist at priority.
Possibly the beats you feel are premature beats. the first thing required in their work-up is an ECG followed by ECHO and if your ECG shows premature beats, ECHO is normal & you do not have any symptoms, nothing is to be done. if ECHO is normal and yuo have some symptoms, it can be managed by a single drug.
In the meanwhile try to remain calm/relaxed, do not drink too much of tea/coffee. if you are taking any anti-asthma/common cold
medicine, they may also cause this.
feel free to discuss further.
