Reading with interest comments by my fellow heart patients. I have had a rough summer and fall. Hospitalized twice for afib. Second time I was taken to hospital by ambulance. I had been in Dr.office, unrelated to my heart condition and the nurse informed me that my pulse was 160 and she was having trouble finding my blood pressure. Fast forward; my Dr. told me that my HCM does not lend itself to another ablation procedure. I have had two and each one gave me two years of freedom from afib. I was cardioverted to get back in syn and am now on a drug call Norpace. In addition I have been taking .20mg of metoprolol and .20 of a water pill. I am now and have been in sync. However this drug gives me terrible stomach gas, makes me constipated and I do not have much energy. I have also lost about 10 pounds. From 182 to 172. I am 80 plus. Have been physical active all my life. Is anyone taking this drug and do you have similar symptoms. Thanks.
