Thanks for posting in HCM
I have understand your concern

you have mitral valve prolapse it leads to regular palpitations secondary to atrial fibrillation
propranolol is a nonselective beta blocker used to control anxiety , palpitaions
your heart rate is lower than normal range
you may have heart blocks or propranolol induced bradycardia
dizziness is secondary to your low heart rate , that causes reduced blood flow to brain
so i can suggest you to get done ECG , 2D ECHO and HOLTER monitoring to check for rhythm distrabances and we can decide about further plan
you need to change propranolol to another drugs like tab . verapamil 40 mg thrice daily .it doesnt reduce the heart rate

Some days, while just sitting, driving, or even laying watching TV, my heart rate is upper 80s-100. Then other days it s low 60s and 70s while doing same things, and on those days it takes much longer during excercise to even get my heart rate close to my aerobic target rate. After stopping excercise, my heartrate comes way back down within 2-3min while other days stays around 100 even for hours after excercising. Should any of this cause me concern? I m 43, 165lbs, 5 9 . Have always been athletic and active, though with ups and downs over time. Have lost a solid 45lbs in the last 3years through excercise and better diet .
