Hello!! I am scheduled for a pacemaker on Thursday! I am 51. I have been trying to get in shape for several years-finally found out why I was failing at any strenuous exercise( sweaty and felt horrible pounding in chest/neck). According to my stress test, my heart rate did not get above 50...I am very nervous, but hopeful. I was hoping for some tips on post op sleeping, pain relief, etc! Also, will the pacemaker help the pounding feeling? Thank you all so much in advance!!
