Feeling worst-CRT pacemaker
I too have a CRT pacemaker( following complications after having a dual lead pacemaker ) causing the left side of my heart to be out of synchronisation with the right. Mine was implanted almost 3 months ago. I agree with Gemita, go back to your doctor because you should be feeling well. Are you on any medication that could cause lightheadedness? You shouldn’t be feeling breathless. What is your usual pulse rate and BP? I hope you get answers soon and feel better.
