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