When we acquired the Apple Watch Series 4 in 2018, we couldn't help thinking that we could have electrocardiograms with a device like this. However, we are not only more realistic, but also more accurate than expected in fact, since then we have been able to see what this feature is like. it has made many users aware and the health of their heart, protecting them from serious future health problems.
However, we should be aware that this device has its limitations, and that currently "only" can help us detect atrial fibrillation that may, or is, an important factor, only a small part of all that can harm our health. Specifically, the fact that you can only do shunt electrocardiograms It's too limited on the Apple Watch, or at least, it was too far away.
According to El Confidencial, Miguel Ángel Cobos, a cardiologist at the San Carlos Clinical Hospital in Madrid found that it is possible to perform complete electrocardiograms via Apple Watch. In order for this to change its position it mimics those where the electrodes of the old ECG would be positioned, that is, the left forearm, leg, and various parts of the thorax. In this way, the information obtained from these tests is very similar to that of a standard health device.
