Interestingly my resting (and by this I mean just sitting at my desk) heartbeat according to my watch is arround 70-80 today, maybe I was just stressed yesterday, although I haven't cycled in today. I'm still going to see the doctor to be on the safe side as the ride home yesterday which is more uphill it got to 193 peak bpm. Both rides were not the quickest I have done it.
According to Strava the point when I peaked was a max 8% gradient, it is only for a very sort time but the only way I could put less into it would be to get off and walk and I am already in the lowest gear at this point.
You say you're only doing 4mph, but on what gradient? Even if it's only 10%, at your weight that would be ~250 watts, which is a lot of power for someone who is unfit.
