Hello everyone, I had a pacemaker implanted on Oct. 9. I have congestive heart failure with an EF of 20. Since the procedure, I haven’t noticed any improvement with my shortness of breath and fatigue. My cardiologist says it will take time (I had two blood clots after the procedure) but everything I’ve researched says I should be feeling much better by now. Do any of you have experience with pacemakers? Thanks.
