What is ECG (Electro Cardiography)?
Electrocardiography is used to evaluate the electrical impulses which immediately precede the contraction of the heart. This method causes no discomfort to the patient. When using this technique doctors will connect electrodes to the chest, wrist and ankles that are connected to a recording machine. This machine will display the electrical activity in the heart as a trace on a rolling graph or screen
No preparation except a clean skin is required. The procedure takes only a few minutes.
- Six electrodes are kept over the chest and four over the limbs
- The wires (leads) connected to the electrodes transmit the electrical signals of the heart to the EKG machine which records it on a moving paper
