If the rhythm is abnormal, it should be treated before you return to your exercise program. I would consider a cardiac event monitor to capture an episode and identify the underlying rhythm. If the tachycardia does not resolve soon, you should meet with our physician and discuss an evaluation plan. It is also possible that you have an underlying heart rhythm disturbance that was “treated” by the beta blocker. ![]() It is possible that you are sensitive to beta blocker withdrawal and the rapid heart rate is a response to stopping the drug. The research described sensitivity to medications that stimulate the beta receptor sites, which results in a racing heart rate and increases in angina. There was a fair amount of literature in the early 1980’s addressing beta blocker withdrawal in the face of heart disease. For me, the receptors are activated at the thought of public speaking, and using beta blockers helped me overcome stage fright.

Will I need to back off of my mileage and pace to retrain my heart, or is this a temporary adjustment to life without Tenorectic? Thanks-Bobby I had to cut the run short at five miles and call it a day, partly because I was worried that my heart would explode and because the higher heart rate wore me out. After a week of weaning off of the Tenoretic, my heart rate while running has gone through the roof-it climbed as high as 170 beats per minute on one run. Recently, my blood pressure improved and my doctor took me off of one of my medications (Tenoretic). I also lift weights and do yoga two to three times per week. I'm 36 and have been running for a little over a year-usually 15 to 20 miles a week. I was diagnosed with hypertension 10 years ago.
