Converted- But for how long?

A side issue--I was demonstrating my wrist monitor to a fellow fibber on Fri eve

at the dance studio we frequent. My readings were ninetyish but his were in the

130s.

Yet his pulse was strong, regular and at about 60 bpm. His wife--an

RN--confirmed that he was in NSR. Is there an explanation for this?? This

fellow's wrist is significantly larger than mine but the cuff fit ok. I don't

understand this discrepancy.

does the watch have a chest strap or is it just a watch? There a many

things that can interfere with heart rate monitors including

computers/computer monitors/mobile phones/ car engines.. it's a long list.

Given he was doing around 60 but the watch was showing around twice

this your watch might not be good at distinguishing the different

voltage changes in a normal cycle. Perhaps the p and q waves (i.e.

atrial and ventricular contractions), especially if the chap had a high

P wave, were coming in as two beats? or perhaps the QRS was causing

two separate spikes on the watch?

It's quite a complicated job converting voltage changes into beats per

minute and I'd certainly recommend a watch that has a chest strap (and

one that says 'ECG' accurate or gives you the tolerances for heart rate

measurement). It's also a good idea to use ECG gel on the chest strap.

Thanks for the response. The wrist monitor is an Omron type monitor that

measures systolic and diastolic pressures and heart rate. One can watch a little

heart image respond to each heart beat and--I presume judge if the intervals are

regular or not. You raise several interesting points: Are some individuals'

ventricular and atrial pulses registered separately? The monitor is factory

calibrated to within three per cent and there were no electrical

interferences--his wife's and my rates were correct (she of course was in NSR).

Admittedly an EKG is more accurate. I guess the most likely explanation is that

he had a high p and q wave registering as two beats-not that I know what p and q

waves are. Just know they need to be minded.
