How is the ECG performed?
You will lie on an examination table, and 10 electrodes or leads are attached to your chest. The electrodes detect the electrical impulses generated by your heart, and transmit them to the ECG machine. The ECG machine produces a graph (the ECG tracing) of those cardiac electrical impulses. The electrodes are then removed. The test it self takes less than 6 minutes to perform.
For male patients only is it better if you shave your chest prior to your appointment due to electrodes or leads which are attached your you chest this makes the procedure less painful.
