Smartwatches have experienced a notable expansion in their health applications to the integration of Electrocardiographic (ECG) tracing recording. Some of these devices have received approval for the detection of Atrial Fibrillation (AF). However, in ischemic heart disease, the main cause of cardiovascular mortality, their role is not established. Small studies suggest that smartwatches may be useful for detecting ischemic changes, which could have significant implications for patient management and care. Obtaining a 9-lead ECG using smartwatches may help in this field by obtaining limb and precordial leads ECG. In this article, we review the existing evidence in ischemic heart disease, the methodology for obtaining a 9-lead ECG with the smartwatch, and future expectations in this field
