atenolol and heart rate?

[jarvis]

Taking atenolol for high blood pressure, 25mg daily. Heartbeat drops to 58 early morning and 72 evening. Do I need to contact doctor?

Do you take the Atenolol in the early mornings? That would most likely explain your early morning heart rate of 58. If you take this drug once a day, the efficacy wanes as the day goes on and your heart rate may increase. The average heart rate is 80 to 100, so I would not worry about a heart rate of 72 at all.
