An electrocardiogram (ECG), also known as an electrocardiograph, is a valuable instrument used to evaluate the rhythmic activity of the heart. During a resting ECG, a subject remains still while electrodes are placed on their chest, arms, and legs. These electrodes record the subtle electrical signals generated by the heart as it contracts. The rec

An electrocardiogram (ECG) or electrocardiograph at rest is a fundamental method in cardiology. It provides a snapshot of the heart's electrical activity while a patient is quietly resting. This baseline assessment helps to detect any abnormalities in the heart's rhythm or electrical signals, which can indicate underlying medical issues. During a r
