Taiwanese company Mio Technology was the first to announce a lightweight portable ECG recorder made in the form factor of a watch. This medical gadget is aimed at users suffering from heart disease, who need to constantly monitor the work of the heart. Moreover, when getting to the electrocardiogram in the clinic is not so simple, unless, of course, you go to a paid medical institution. The waterproof MiCor A100 cardiac activity recorder takes readings at any time convenient for the user, and in case of detection of an irregular heart rhythm, records the most important 30 seconds. If this is possible, the testimony can be sent to the attending physician to prove a malfunction in the patient’s heart robot, then examine them and make corrections if necessary. The release date and cost of the device are not known.
