A resting electrocardiogram (ECG) serves as a fundamental tool for evaluating the heart's activity. During this non-invasive procedure, electrodes are placed on the chest and limbs to record the electrical signals generated by the heart. The resulting ECG tracing provides valuable information about the heart's frequency. By establishing a baseline
