Electrocardiogram devices (ECG)
ECG devices record the heart rhythm based on the electrical excitation of the heart during the heartbeat. The ECG examination is useful in cases of high blood pressure, cardiac arrhythmia or arteriosclerosis, among others.
A distinction is made between long-term, resting and exercise ECGs. Long-term ECGs record the heartbeat over a longer period of time, for example if irregular heart rhythm disturbances occur. The resting ECG is carried out on a lying, relaxed person, while the exercise ECG is used during physical exertion such as on a treadmill.
