Last year I started getting severe dizziness with lightheadedness and nausea. I've seen a cardiologist, neurologist and ENT and all that was found was mild MVP and trace tricuspid reg. with no lesions. I've been on propranolol 20 mg b.i.d for 4 or more months. It was increased from 10mg b.i.d. because my heart beats really hard and jumps up to 125 BMP upon standing. I am slowly lowering the dose because it's causing my BP to be 90/70. My heart rate is normal until I stand for long periods and it shoots up. As soon as I sit down it instantly drops down but pounds extremely hard. I do not have any pain but I still have these dizzy, lightheaded spells with nausea. I also feel like my heart stops for a second, then pounds really hard to start again. I have told my doc all this and he says I'm fine. Stress makes it worse too. I am 5'7, 117 lbs, very light smoker, no caffeine or alcohol. I had heart tests, EKG, echo, stress echo, holter and event monitor, and tilt table test. Am I having side effects of this drug? Could this be whats making me feel so lousy and tired and keeping me pretty much bedridden? Is the extreme heart pounding dangerous? Should I get a second opinion from another cardiologist?Reply Follow This Thread Stop Following This Thread Flag this Discussion
