Electrocardiography
Smartwatches
ECG technology is also available in smartwatches. Such smartwatches use a single electrode sensor placed on the wrist to measure the heart's electrical activity. This kind of ECG can detect arrhythmias, including Atrial Fibrillation and Atrial Flutter (Afib), which is a type of abnormal heart rhythm. Unlike a standard 12-lead ECG, smartwatch ECGs allow for continuous monitoring of heart activity, instead of a single brief period. However, smartwatch ECGs are typically not as accurate as 12-lead ECGs and do not detect as many different cardiac conditions.
