I receive my unit on the 28th of this month. I am having a lot of anxiety. I have a low heart rate that borders on bradycardia and I'm having frequent PVCs that are symptomatic. When they try any meds to control the PVCs it drops my heart rate down and I get lightheaded. They are hoping the the pacemaker combined with beta blockers will get me lined out. Thankfully I have no "plumbing" issues. All of mine are "electrical" but still very scary for me.
