“…Within this group, two subgroups stood out, the first of which did not name all the components used, particularly the sensor devices, but, rather, stated that they composed their own wearables from sensor devices. Thus, in [ 39 , 41 , 42 , 43 , 46 , 48 , 50 , 51 , 54 , 56 , 58 , 59 , 60 , 61 , 62 , 66 , 86 , 88 , 92 , 116 , 118 , 123 ], the authors proposed custom-built wearables with unspecified components. These studies were able to detect various cardiovascular diseases such as atrial fibrillation, atrial flutter, atrial premature contraction, atrial tachycardia, cardiac asystole, cardiovascular risk, fusion beats, heart attack, heart failure, hypertension, myocardial infarction, myocardial ischemia, premature atrial contractions, and premature ventricular contractions.…”
