An interesting thing I experienced with my new 935 watch....
The optical heart rate sensor on my 935 seems to be on par with what I can count when I try to count my pulse rate with my fingers(radial artery) and what I am getting when I am letting the blood pressure monitor do that work.
Now... these values differ from what I can read from my Garmin HR Strap sometimes, especially when I am changing my activity level fast like doing 10 push ups and going to a sitting position afterwards. The heart rate strap seems to deliver also correct values compared to a small mobile ecg device.
It seems like the heart rate strap - electrical heart rate is like 10 seconds faster and goes also higher than my actual peripheral pulse output is (measured with fingers, blood pressure monitor).
It is also about 10 seconds slower when changing to a lower HF/Pulse level after a short intense activity meaning that my HF - electrical heart rate can be as high as 110-120 while my actual pulse is already down to like 90 or 80(935 OHR and manual count).
Anybody has an explanation for this? I always thought that alectrical heart rate and pulse should be the same?
Maybe my one year old hf strap got already defective/less responsive and my portable ecg device is not working correctly after some intense activity due to too much movement caused by heavier breathing?
Is there any known desease where pulse and electrical heart rate are drifting apart like that?
The photo attatched is what I recorded while doing some mixed low intensity activity. In grey you can see the aux heart rate from my hf strap compared to the optical heart rate from my garmin watch (Herzfrequenz - red). While recording this I compared the values to my manual measurement from time to time and I felt that my pulse was more like what my garmin watch was showing than the electrical heart rate coming from the hr - strap. ciq.forums.garmin.com/.../1263959.png
