Thanks for writing in.
I am a qualified and certified cardiologist and I read your mail with diligence. You have to be aware that human heart beats for about 100,000 times a day (72 x 60 x 24); a small percentage of them can be normally missing. Some people are perceptive of this. They have the symptom of missed beat. What concerns me is your correlating electric shock
sensation with irregular beats My suggestion is to take an appointment with a medical specialist. Explain this symptom to the doctor. If the doctor is convinced after thorough medical examination and EKG, an holter examination will be done in which EKG is recorded while you are doing your normal work for a day. Results are analysed with help of a computer. That will confirm your assertion that arrhythmia
or heart beating out of rhythm is responsible for symptoms. Additionally an echocardiography
may be done to assess ventricular function Treatment shall be initiated for the type of arrhythmia if needed. No your symptoms are not because of gas though the underlying condition may be as benign Good Luck.
