Resting ECG and stress ECG (electrocardiogram)

The ECG is used to record the electric currents of the myocardial muscle that occur with every heartbeat. The graph of the electrical activity of the heart or “Herzstromkurve” is derived by electrodes that are fixed to the skin. Heart rate and rhythm are reliably shown with the ECG. Furthermore, ECG alterations provide evidence of circulatory disturbances, inflammation or risk of a heart attack.

The stress ECG is the most important examination method to judge cardiac function. It allows diagnosis of cardiac arrhythmia caused by strain. The stress ECG is carried out on a modern bicycle ergo meter in a sitting position.
