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.
Your doctor will diagnose a heart attack based on your signs and symptoms, your medical and family histories, and test results. An EKG is a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through each part of the heart. An EKG can show signs of heart damage due to coronary heart disease (CHD) and signs of a previous or current heart attack.
