My father had gone bypass surgery and brain stenting two years back. He is doing well know but his pulse rate suddenly came to 55-58 while resting and after walking 70-80. But most of the time while sitting it is 55-58 while earlier it is above 65 (BP-115/70)He is taking metosartan 50 , clopivas 150, atorva 40 and glycomet 500. Is there any issue or is it normal. He is feeling fine no symptoms as such. We are hesitating to go for ecg right now because of the situation outside of corona risk. Kindly suggest.
