Abstract:
A 67-year-old man with a history of smoking, hyperlipidemia, and hypertension complained of central chest pain radiating to his left arm for 2 hours and contacted the attending cardiologist. Based on medical history and symptom description, the physician urged him to undergo a complete cardiac evaluation to rule in or out an acute coronary syndrome. Interestingly, the patient insisted on sending digitally for tele-consultation a lead-I tracing recorded by his Samsung Galaxy Watch 4 (Samsung Electronics) worn on his left wrist.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
Parts of an ECG
An ECG utilizes electrodes on the skin...
Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
