Hi there Elizabeth. I hope you are feeling better. So good to have you willing to share your knowledge and expertise. I am a woman in my 80s and after a week long holtar test, my cardiologist urged a pacemaker. Why? Because my heart had "paused" for 2.7 and 2.8 seconds at night when I was asleep and also had raced at 145 for a few seconds. He would like to give me more beta blocker but is afraid that such a treatment could lower/stop my heart. So he is urging a pace maker. I am rather reluctant to go that route. Another cardiologist suggested medications and a pace maker as a last resort. My GP thought I should go for the pacemaker as it is a certain fall back. In short, I am anxious about the pacemaker. Any thoughts?
