Electrocardiography is a quick, simple, painless procedure in which the heart’s electrical impulses are amplified and recorded.
. Graphic record of the electrocardiography is called electrocardiogram (ECG, EKG). It is based on recording of electric potential generated by heart on body surface. This methode is used in diagnostic of heart disease.
It is used routinely in physical examinations and for monitoring the patient's condition during and after surgery, as well as during intensive care. It is the basic measurement used for tests such as exercise tolerance. It is used to evaluate causes of symptoms such as chest pain, shortness of breath, and palpitations.
Chest Sensor Application:Place the 6 Chest sensors on the patient’s chest as follows:
V1 Fourth intercostal space at right border of the sternum
V2 Fourth intercostal space at left border of the sternum
V3 Midway between position V2 and position V4
V4 At the mid-clavicular line in the fifth intercostal space
V5 At the anterior axillary line on the same horizontal level as V4
V6 At the mid-axillary line on the same horizontal level as V4 and V5
Attach the chest leads.
To help identify primary conduction abnormalities, cardiac arrhythmias, cardiac hypertrophy, pericarditis, electrolyte imbalances, myocardial ischemia, and the site and extent of myocardial infarction.
To monitor recovery from an MI.
To evaluate the effectiveness of cardiac medication.
To assess pacemaker performance
To determine effectiveness of thrombolytic therapy and the resolution of ST-segment depression or elevation and T-wave changes.
You can breathe normally during the electrocardiogram. Make sure you're warm and ready to lie still. Moving, talking or shivering may distort the test results. A standard ECG takes a few minutes.
imb leads are made up of 4 leads placed on the extremities: left and right wrist; left and right ankle.
The lead connected to the right ankle is a neutral lead, like you would find in an electric plug. It is there to complete an electrical circuit and plays no role in the ECG itself.
