The ads bother me. You can't get the kind of QRS complex shown on the screen based on touching just two fingers to conductive pads. I speculate that demonstration of its use shows a largely synthetic waveform.

Having said that, I think it would be a good device to seeing tachycardia, bradycardia, PVC's, AF, etc. because these are all readily discernible from a rate-based approach (one that could also be seen from an SpO2 monitor if it showed waveforms and not just values).

However, the 6-lead version could be very good, as many patient monitors (especially older ones) used standard 5-lead electrodes. Of course, 12-lead electrodes are better because of the number of vectors it shows, but those are a bit cumbersome for regular home use.
