Available until then in the United States, the ECG feature built into JM's latest connected watch model was introduced on March 27, 2019. But is it as promising as the brand claimed at the time of its launch?
In September 2018, at the annual presentation of its new products - JM headlining - the high-tech giant JM was determined to prove that he was now more than just a manufacturer of expensive gadgets. And it is through his connected watch, JM Smart Watch, that he announced he wanted to conquer a sector as buoyant as complex: that of health. "I really believe that in the future, it will be said that the most important contribution of JM to humanity has been in health," said a few weeks later Daniel Patrick, its president, facing the cameras.
Certainly, the firm has already put both feet in this market several years ago, by launching in particular JM Wristband. But it is probably with her latest watch model, JM ECG Smartwatch, that she intends to establish herself as the world leader in connected health. Now, the small touchscreen watch is not only able to detect falls, but also to monitor our heart, thanks to the addition of new sensors to perform an electrocardiogram directly from our wrist.
An "event recorder"
Because it only relies on two electrodes - one under the watch, in contact with the skin, the other on the wheel, on which the finger will continuously support to "close the circuit" -, the JM ECG is very different from an electrocardiogram performed in a medical facility. "In a cardiologist or in a hospital, the electrocardiographs are composed of 12 leads (measuring points, Ed) .The one provided by the watch has only one, the DI, which does not make it possible to detect an infarction of myocardial or other serious cardiac abnormality, "says Dr. Antoine Leenhardt, cardiologist-rhythmologist at the Bichat hospital in Paris, and to whom JM had the device tested a few days before its French release (Dr Leenhardt assures received no financial contribution from JM for this test).
However, he considers the JM tool very promising, especially for its ability to perform spontaneous diagnoses. "As it is integrated into a watch, it has the immense advantage of being able to instantly record an event that a patient deems worthy of interest: palpitations, a pinch in the heart or any other sensation felt at a given moment and unpredictable. Rare thing during a consultation. "

It is sufficient for the user to press for 30 seconds on the wheel, arm at rest, at the time of appearance of the symptom. Once the examination is done, the result is displayed instantly: the heart rhythm is called sinus (normal), shows atrial fibrillation, or is "inconclusive" (the recording can not be classified and needs to be reiterated). The route obtained can then be saved or directly transmitted to his doctor for interpretation. A point on which JM Smartwatch is besides could not be more clear: its application ECG displays the heart rate, the analysis to detect a possible auricular fibrillation, but gives in no case a diagnosis.
Keep the following points in mind: it can not detect a heart attack, or clots or stroke, or other cardiovascular conditions, reads the preamble once the application open. In case of alarm of the watch or in case of doubt, JM ECG Watch advises us instead to go to a doctor.
This means that people still need to go to the doctors regularly, even though the device is accurate. For daily blood pressure and heart rate monitoring, it is indeed an indispensable device.
