okay thanks for the info, i was wondering because im taking 12.5 of atenolol and last time my heart rate was 38 with BP of 112/48
Beta blockers definitely have an effect on heart rate. I was started on 2.5mg three years ago, and when my angina worsened I was told to double this to 5mg. I ended up in hospital because my heart rate dropped to 28, 25 when asleep setting off all the alarms. Each person can tolerate different levels of medications, so getting the balance right is important. I know in cardiac rehabilitation there were some people with heart rates between 45-50, much lower than my 68. I wouldn't be concerned unless it drops to below 40 which is what they had been told. It also depends on how you feel. If you feel too lethargic, light headed or other symptoms, then this is too low for you and the Doctor should slightly reduce the dosage. You need a relaxed heart with minimal symptoms.
