Abstract:
Wearable electrocardiogram (ECG) technologies have emerged as promising tools for continuous cardiac monitoring during physical activity. However, evidence regarding the accuracy of single-lead wearable ECG systems under dynamic exercise conditions remains limited. We evaluated the performance of a wearable chest-band ECG device by comparing simultaneous recordings with a conventional multi-lead exercise ECG system during rest and graded cycle ergometer exercise in healthy volunteers. Agreement was assessed using RR interval measurements, heart-rate metrics, and complementary agreement analyses, including participant-level correlation and Bland-Altman evaluation.

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 to...
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.
Purposes
Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
