I am new to the site,about two years ago ihad a heart pacemaker fitted.This as severely restricted my ability to climb steep hills.It was fitted as I was found to have an irregular heartbeat.Just wondered if there is anyone else on here who has a pacemaker.Im 68 years old and have cycled and ran most of my life,but am finding it hard going on the bike now,but do not want to quit as it is beneficial to my health.
