I am on atenolol for hbp and heart rate. both spiked a lot so Ive been on med for 10 years. I notice that my heart rate usually resting is about 70-80 but after eating at least 90. If I walk around after eating it goes up to 100 - 110. Is this ok or not. sorry for all the questions. also sometimes I start to tremble inside and then both bp and rate go up. Is the trembling causing the spikes even when Im on medication or is the rate and hpb causing the trembling.
