Any runners on here to explain ?
I'm nearly three months in to having my pacemaker (second degree heart block) and started a couch to 5k running programme to ease me back into running.
My maximum heart rate a few months before my pacemaker was 185ish and at this effort I would have been running around 6 minute/mile pace.
Today my pace was almost walking pace running at exactly 10 minute/mile pace and my heart rate shot up very quickly to 165 and then after a mile or so sat at around 175. I was barely breathing it felt that easy.
Why would my heart rate be going so high and so quickly for very little effort?
Is this something that calms down with time or is there something in the settings artificially increasing my heart rate to high levels?
I know it's still early days but if this is all correct then I am going to max my heart rate out at a running pace that is extremely slow.
I have no problems with the sinus node.
