What could interfere with the successful recording of an ECG?
The Vitaphone Tele-ECG-card 100 IR needs bare-skin contact with the user in order to guarantee correct function – therefore, a hairy chest could interfere with the successful recording of an electrocardiogram. This also applies to heavy perspiration (the device is NOT waterproof) The Vitaphone Tele-ECG-Loop Recorders use adhesive electrodes which must also enjoy good contact with the users dry skin in order to function correctly. When using the Vitaphone Tele-ECG-card 100 IR, it is essential to assume a relaxed position, assure good contact with the skin and avoid movement.
