Not only a small sample, but a sample taken from a very specific class of testers; those who wear the latest Apple watches..5% and not really a scientific study.
Jason- I have a couple heart rate monitor apps that work very well. But I have a pacemaker/ICD. Before I had the device adjusted for a range between 50 and 120 BPM, it was set for a fixed 72 and the monitor was spot on never deviated as it should. After the EP MD reset it so I could exercise, get elevated BPM, it not accurately tracks it within that range. Before I suffered my cardiac arrest I suffered bradycardia, or abnormal slow heart rate. Typically I would function normally with a resting heart rate of 40-45 BPM. When sleeping it would track as low as 35. Exercise would elevate to 70-140 however. The EMT report says that when they got to me my heart rate was 15BPM and I was unconscious. In the Ambulance, in my driveway, they reported complete cardiac arrest and began CPR. Needless to say it was a close call. In ER they put an external pacemaker on me but I was in a coma for a half week.
Bradycardia is a serious medical problem but a pacemaker solves the problem.
Currently, I find the ECG in the AW4 too sensitive to electronic noise and difficult to get a good reading. However, when I do get a reliable reading it says sinus rhythm detected. I get the multi lead ECG reading every 4 months and so far my good readings have matched the medical device charts. When the bad reading happens it does not give a false positive or fail to detect AFIB, as compared to my 120 day full time monitor readings, it just says "inconclusive" ( My pacemaker / ICD records my ECG constantly and each night uploads the data to Medtronic with a home sending device connected to the cell phone network while I sleep). I don't know why my AW4 is so sensitive to noise, whether it may be my pacemaker interfering or whether it is the metal band I use as opposed to the non-metal band. I could test that last part but I wonder if other pacemaker patients also have trouble with reliable readings? Ok as I sit here I just tested it and got a perfect "sinus rhythm" chart at 70 BPM so this time it worked fine. I am 5 ft from my wifi router and surrounded bu computers with open cabinets so I doubt RFI is the cause of the noise when it doesn't work.
Oh, and I was not one of the volunteers in Apple survey. I have had surgery 2 years ago to ablate my atrial node as it was causing conflict with the pacemaker and sending me into atrial flutter.
Jason, I use an app called Cardiogram that monitors the heart rate constantly or measures it often with options to measure it constantly. It then displays a bar graph of the data for the past 6 hours.
That's normal. Bradycardia is well below 50, like 35-45 when at rest. My father suffered from it too and had to get a pacemaker to elevate it above 60 at rest after he turned 75My heart rate varies when I’m just resting anywhere between 55-80 beats a minute depending on if something has me stressed or excited.
I do have spells every now and then of dizziness but that’s usually if I get up too fast or turn around too quick. It only happens every so often and usually happens when my sinuses are acting up like during allergy season.That's normal. Bradycardia is well below 50, like 35-45 when at rest.

If you begin to have spells of tunnel vision, dizziness when standing up, or even feeling faint to blacking out completely, then get medical attention right away.
Start monitoring your BP regularly. I use a Qardio cuff that automatically keeps a log on my iphone. The allergy season can cause blockage of the Eustachian tubes that equalize air pressure in the middle ear. If this is not equalized it can also cause vertigo similar to low blood pressure symptoms. High BP is mostly asymptomatic until is causes a serious health issue.I do have spells every now and then of dizziness but that’s usually if I get up too fast or turn around too quick.
On my series 3 the heart rate monitor seems OK but something is sucking down the battery faster.Anyone else seeing issues with the heart rate monitor since 5.2.1 came out? Mine either won’t show the last reading/update the reading, or says tap to measure.
