Hi Guys, Hope all are doing well. I am 18 days post-op and still have rapid heart beat (over 100 bpm). Prior to surgery (AVR bovine) my heart rate was running pretty regular about 70bpm, now it runs consistently between 90bpm and 110 bpm at rest. I must be more concerned than my cardiologist because he says well lets just wait a while and see. All I take for meds is 1 50mg Toprol xl /day and 1 adult aspirin tab. The toprol is mainly for blood pressure but it is also supposed to help lower the heart rate. Anybody else out there going thru a similar experience and should I maybe fire my cardiologist and find another??? Thanks Dave
