Holter monitors do the job reliably, but they are far from being comfortable, even if you manage to somehow find a tolerable sleeping position with the bulky box, it will wake you up several times during the night inflating the cuff. 24-hour measurements are clearly more informative than sporadic readings – and we also have to mention that there is no guarantee that patients carry out the measurements properly with a traditional device. This is why I had high hopes when starting to test the BioBeat 24-hour blood pressure monitor.

The technology itself is based on reflective photoplethysmography (PPG), a noninvasive optical method which measures the heart rate, blood oxygen saturation, blood pressure, and several other cardio-pulmonary parameters.

I have tested several blood pressure monitoring devices in the past few years, but none of them have truly delivered so far. While the iHeart was pretty convincing as a blood pressure monitor, it didn’t offer much more than a traditional device with a fancied-up look. The Omron on the other hand was plain useless as a smartwatch. So, let’s see what we can expect in this area today.
