The main purpose of the 12-lead ECG is to screen patients for possible cardiac ischemia. It helps EMS and hospital staff to quickly identify patients who have STEMI (ST elevation myocardial infarction or in other words, heart attack) and perform appropriate medical intervention based on initial readings.
The wave pattern should have a consistent shape. If your waves are not consistent, or if they do not appear as standard waves, this is indicative of heart disease.
Yes the information on ECG basics is based off of healthy hearts/patients. It is absolutely possible to have a normal axis with a prior inferior MI. Hope this helps.
ECG is the abbreviated term for an electrocardiogram. It is used to record the electrical activity of the heart from different angles to both identify and locate pathology. Electrodes are placed on different parts of a patient’s limbs and chest to record the electrical activity.

The room in which the electrocardiogram is performed should be ventilated and with an optimal temperature regime, since a cold sensation during the procedure may negatively affect the reliability of the results of the study.
Changes in the structure of the heart and its surroundings (including blood composition) change the patterns of these four entities.
The principle of the ECG is based on the ability of the device to capture the electrical impulses that arise in the heart and, after processing, record them in a graph.
Many doctors order an ECG as part of a yearly medical examination to screen for heart disease. This may apply to you if:
Your doctor may suggest you get an electrocardiogram -- also called an EKG or ECG -- to check for signs of heart disease. It's a test that records the electrical activity of your ticker through read more small electrode patches that a technician attaches to the skin of your chest, arms, and legs.
The ECG carries pelo danger to the health of the patient, since during the examination, X-ray irradiation and other factors harmful to the organism are not applied. If necessary, this method of examination can be repeated, even at short intervals.
ECG is a safe test that does not cause health complications. There are pelo medical conditions associated with an increased risk or adverse side effects from ECG.
To the trained clinician, an ECG conveys a large amount of information about the structure of the heart and the function of its electrical conduction system.[7] Among other things, an ECG can be used to measure the rate and rhythm of heartbeats, the size and position of the heart chambers, the presence of any damage to the heart's muscle cells or conduction system, the effects of heart drugs, and the function of implanted pacemakers.[oito]
ECG machines are standard equipment in operating rooms and ambulances. Some personal devices, such as smart watches, offer ECG monitoring. Ask your doctor if this is an option for you.
