Hi Joannfran,
My situation was exactly the same as yours , I have been diagnosed with pvc’s after a 5 day heart monitor but I also have high blood pressure, the propranolol made me feel dizzy , tired and very fuzzy spacey head and unfortunately for me caused a psoriasis flare , which I’d had under control for years so had to come off it , I was given diltiazem 120mg slow release and it worked great no palpitations but unfortunately I got dreadful flushing as a side effect to the point of having drenching sweats , doctor then changed me to vepramil another calcium channel blocker but I have it in immediate release at 40mg 3x daily and works amazing no side effects, no palpitations, try the diltiazem if it doesn’t suit the next option will be vepramil I think there’s only those two classes of ccb’s that control heart rate or it’s the beta blockers good luck hope it works for you , don’t be scared to try it , it may work great and you will be free of the pvc’s I know how horrible it is living with them for me the caused unbearable anxiety.
CLKD , two types of calcium channel blockers are used to treat heart arrhythmia as well as high blood pressure, beta blockers don’t suit everyone so there are other drugs cardiologists use such as the CCB’s x
