3 months ago I had coronary artery by-pass surgery and seemed to make an excellent recovery. I returned to hospital for a check-up after 6 weeks, and was again told that all was well. I had had no chest pain at all during this time, even when taking exercise.
The very next day I experienced severe chest pains and was taken back to hospital, where it was discovered that my heart rate was very low, and while being monitored over the next 5 days, I had several 'pauses'. I therefore had a pacemaker implanted a week ago, but the chest pain returns when I walk, normally after 300-400 yards.
My question is - would it be expected or posssible for me to have angina pains after the treatment I have received - what is the possible reason for it?
