Hello, Thank you for your query. * what is your height and weight? * how old are you? * do you smoke? * do you have any other medical issues or take any medications? * when you have these symptoms, do you face any other difficulty like breathlessness, chest discomfort, giddiness, headaches, stomach aches or bloating? * do you take any supplements?or health booster medication? or recreational drugs? Based on your query, I would like to check for heart blocks and arrythmias (heart rhythm disorders). I recommend: - a physician consult - an electrocardiogram, holter monitoring if required - an echocardiogram - blood tests ( electrolyte levels , complete blood count , kidney and liver function tests) Based on these we can find out if treatment is necessary. please make sure you see the doctor when you are symptomatic. do not delay. hope this helps. wish you good health
