Electrical axis and recording lead vectors (see Figures 2 and 3) The ECG is measured by placing a series of electrodes on the patientâs skin â so it is known as the âsurfaceâ ECG. The wave of electrical depolarisation spreads from the atria down though the IVS to the ventricles. So the direction of this depolarisation is usually from the superior to the inferior aspect of the heart.
So, what is an ECG test? And what does an ECG measure?An ECG, the abbreviation of electrocardiogram, is a test that measures the electrical activity of oneâs heart. The ECG test records the heartâs rhythm on a strip of paper, or shows with a line on a screen. The peaks and dips of the heartâs contraction are then interpreted by a doctor.
