Hello doctor,

I was diagnosed with SVT in my childhood. I stopped taking medications when I turned 18. I have started working out because I have gained a bit of weight over the years. I will be 30 this year. How high can my heart rate get when working out and doing cardio? I do not want to experience cardiac arrest at the gym.



Welcome to icliniq.com.

Considering your age, you can reach a maximum heart rate of 190 beats per minute. But, as you are taking the tablet Atenolol, I am afraid that you will not be able to reach this target. Besides, Atenolol is known to decrease your physical performance. I suggest avoiding straining physical activity as it can trigger PVC (premature ventricular contractions) and shortness of breath. The most appropriate physical activities would be yoga, aerobics, recreational sports, etc. If you have shortness of breath during physical exertion, it would be better to take a short break. Hope you will find this answer helpful.
