Hello sir/ma?am my mother is a blood pressure patient from 9 years. Since the past few years, I have noticed that her heartbeat is always high in the evening and sometimes in the morning as well. In the morning it is around 75-79, in the afternoon it is 85-90 and in the evening it becomes 90-100. She takes a lot of burps during the entire day. And when she works for some time she feels her heart beating fast. All I want to know is that is it normal to have such a heartbeat or is it a thing to worry. Her cholesterol was normal however her hdl was 35.5. Thyroid is normal. Haemoglobin is 13.4 daily diet is 1 kiwi and 1 beetroot. She eats telma 20 for her blood pressure. Please give your suggestions. And is it normal to have a heartbeat from 90-100? Can the blood pressure medicine increase the heartbeat.
