V lead failure
I’m a newbie. 73 years old, healthy except for node failure....no other cardiac problems. Month ago had a VT incident...heart rate of 230 for a full minute. Echo cardiogram and stress test...all ok. Then a couple of weeks later had to call 911. Passed out and chest pounding and BP way way high...240/130. Finally the replaced both A lead and V lead. Question is...would failure of V lead cause high BP? Epinephrine into blood stream and no way heart rate could increase due to pacemaker? If so why would epinephrine be released? Stress?
