PVC's, exercise, and Atenolol

Posted By Kevin Griggs on November 08, 1998 at 11:37:52:







I suddenly started having PVC's in April. I had a EKG, a 24 hr. halter, and an ultrasound on my heart, all normal. My dr. percribed Atenolol @ 25mg per day, we upped the dose to 50mg per day and I did not experience any PVC's until two weeks ago when they reappeared in full force. One night before bed I was having at least 20+ PVC's per hour at which time I visited the ER. Once in the ER my PVC's calmed down, they monitored me for 1 hr. plus did EKG. They said all was well. Since then I have had almost constant PVC's up to 20 times an hour. Since this all started I have begun and exercise program of riding a bicycle everyday for over an hour at which time the PVC's quit until about an hour after exercise, and I have no problrms during my rides. My question is this. What effect does atenolol have on the body during exercise? I take Atenolol at bedtime and exercise at 4PM. What is the best time to take Atenolol in relation to increased activity? Are there any additional steps I can take to avoid PVC's? Thanks for your advice, I enjoy reading all the questions and answers. Kevin Griggs
