Elevated HR during first few minutes of workout.

Faste HR

We'd have to know  a lot more about you, your condidion, and why you have a pacemaker, before we could even offer a guess.

Yes, I totally realized that after i posted, sorry. 67 year old, lifetime endurance athlete, currently a road cyclist with long backround in track and field. Pacemaker was placed after diagnosed with bradycardia. Had a few a fib incidents in last year as well. Also a leaky valve is in play that will need some attention within the next year or so. My team has given me the go ahead to resume training at the moment, and my numbers on the bike have been similar to pre-pacemaker. Hope that helps. Thank you.

Bradycardia

Do you know the cause of your Bradycardia? "Bradycardia" is a symptom, not a diagnosis. It just means a heart rate below 60bpm, so it doesn't mean much. "Tachycardia", the same, but a rate above 100bpm. It gives no other information.

The reason I ask, is that if the cause is SSS (Sick Sinus Syndrome) the cause would be very different than a heart block.  The pacemaker's function is completely different.  Both would be a cause of Bradycardia.

It would help if you put as much information in your profile as you feel comfortable sharing.  That way you won't have to repeat the information if you have other questions (I forget easily ;-).

I see something similar - and for me it's an artifact

This will depend a lot on exactly *how* you measure your HR.  For me, it's a chest strap (one of two), and both depend on making a good electrical contact with my chest to get a clean ECG signal that isn't swamped by electrical activity from skeletal muscle (usually much bigger voltage).

If I don't moisten my chest strap I often see raised (or even silly) HR values - 175-200BPM) early on.  Then, as I start to perspire, conductivity improves and the strap shows my actual HR.  How do I know?  Finger to carotid pulse: if chest strap reports >165BPM (my upper rate limit) and my finger says about 2 beats per second, I know the strap isn't reading my real HR.

However, don't be a twit as I was.  Years ago when still running a lot, I stopped using the chest strap for my Forerunner as I thought the HR values were silly and wrong: in fact they were correct and I was experiencing 'exercise-induced tachyarrhythmia'.  In other words, your high HR early on *might* be correct.

So you need to check what your real HR is - and only feeling a reliable pulse will give you certainty.
