Hello,
Thank you for your query at DoctorSpring.com
Going through all your previous consults, i see that you developed sinus tachycardia, and the cause was found to be anxiety. And that your ECG is normal.
Before you resume your cardio, i will advise you to get a 2D ECHO done and also a treadmill stress test. The Inderal therapy is not lifelong, and once such episodes disappear, you need to wean off the drug slowly. Though your heart looks fine, but 2D ECHO and the stres test will give a more conclusive picture. If you have the echo report kindly share.
Based on that we can decide your workout schedule.
Regards.
