An electrocardiogram (ECG), also known as an electrocardiograph, is a valuable technique used to assess the electrical activity of the heart. During a resting ECG, a subject remains still while leads are placed on their chest, arms, and legs. These electrodes measure the subtle electrical signals generated by the heart as it beats. The recorded sig

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