High quality ECG paper is needed for reliable diagnoses and accurate results in hospitals and specialist practices. In our shop you will find the right type of recording paper for your equipment - either on rolls or accordion folded. An electrocardiogram (ECG) records the electrical activity of all myocardial fibers. Since cardiac muscles change their electrical properties with each heartbeat, electrodes attached to the body (such as on the chest, arms and legs) can be used to measure changes in the body's voltage.
