Increased Pulse Rate, Weak Heart. Taking Medication. Recommendations?

What kind of virus can cause a pulse rate if any to jump from 78 to 100 from lying down to standing? I take a whole beta blocker in the morning and a half before bed. I also take three 2.5 midodrine three times a day. I'm a male 41 years old 152lb 5.9 and never been sick till now. I was told I have a weak heart 48% and shouldn't workout.

Dear patient,

Thanks for your health concerns. Specifically, I dont think that any virus is the cause of that change in heart rate; increased heart rate after changing from a sitting or laying down to a standing position is a normal physiologic response to compensate for blood pooling in the legs from that maneuver; in some patients, the compensation in terms of heart rate and blood pressure might be suboptimal and might be prone to dizzy spells, which is probably why you are on midodrine.

Hope this is useful, wish you the best health, blessings,
