Electrocardiogram: the cons
One of the "human limits" of wearable technology is its obsession with data. It seems trivial, but while it is correct to monitor them to improve or otherwise to keep an eye on their habits and evaluate the training done, on the other hand should not be overlooked the possibility of error that still accompanies these technologies. In other words, some surveys may still be unreliable. That's why, for example, the electrocardiogram generated by Apple Watch 4 has medical validity only in the United States: in fact, local agreements must be made, which is also the result of a joint review on the effectiveness of the technology used.
Not only that, but the average user who will use these services must be taken into account: is he a doctor? Is he a cardiologist? In almost all cases, no, and this means that he will not be able to scientifically read the results of the ECG. Translated into logistical terms, it could mean an increase in false alarms generated by incorrect data readings that would actually mean a higher number of people who go to the emergency room require specialist visits. Wearing a device that is able to track vital parameters, it is worth remembering, does not make us doctors. But it can make everyone a better sportsman and a healthier person.
