If you faint, as I did walking, you get hurt. Bradycardia is a heart condition. I get the wozzie, dizzy and nausea every day for no reason, with my feet up watching golf, making dinner, laying down to rest or nap or for the night, doing light gardening in the yard. My low EF, PVCs and heart rate don't concern my cardiologist either. The EP ruled out ablation as I have too many spots firing in my heart with late or early beats. Each spot gets fried to stop the extra beats. I have so many firing spots that they can't be fried. So I take Enalapril ( Linsapril was developed from Enalpril) and move slowly, walk with poles or cane to catch myself and remain hopeful.
