The truth is I don't even know when heart is going out of rhythm. But every time I go to the doctor, she know it's out of rhythm. I've been always cognizant of my heart, the extra beats, the twinges I used to feel. But now, I don't know my heart beats out of snych. I guess as I get older (I'm only 53, but I don't look a day over 52) comes the heart problems. My hope is that your pharmacist comes up with a suitable alternative. There a whole class of drugs known as calcium-channel blockers. My suggestion to you is when you read this call your doctor. Only he or she knows your history. That should fix you right up! Or you could ask your doctor about a procedure called Cardiovert or Cardioversion.
