So far everything works without problems, both the pulse oximeter and the ECG.
Operation of the pulse oximeter
ECG Monitor Operation
The only thing is that the ECG is noticeably affected by chest excursions during breathing (the baseline drifts), but overall everything displays fine.
The ECG is recorded from 3 contacts on the back side of the device (where the stethoscope diaphragm is). Before use, it is recommended to apply a small amount of conductive gel to the contacts.
Naturally, one can only judge the type of rhythm; the main waves are clearly distinguishable; there is no way to assess myocardial trophicity. Although it is interesting — maybe if the sensor is applied to different areas of the chest, could one obtain something similar to precordial leads (V1-V6)?
The stethoscope itself also works, it may be a bit quiet, but it is audible. But that is of course not its main function,
