WebMay 1, 2024 · According to conventional teaching, the limb leads in the electrocardiogram (ECG) represent the frontal plane electrical vectors of the heart, whereas the chest leads signify the horizontal plane. ... Fig. 2 is a schematic diagram of the frontal plane of the heart. It shows that compared to the electric center, both aVR and V1 are at ... WebAn electrocardiogram (ECG) is one of the simplest and fastest tests used to evaluate the heart. For this test, electrodes (small, plastic patches that stick to the skin) are placed at certain spots on the chest, arms, and legs. When the electrodes are connected to an ECG machine by wires, the electrical activity of the heart is measured, interpreted, and printed …
