electrocardiograph
Cardiac rhythm recorder
An electrocardiograph is a medical device that records the electrical activity of the heart, producing a tracing called an electrocardiogram (ECG or EKG).
Electrodes attached to the skin detect the tiny electrical impulses that trigger each heartbeat: The electrocardiograph showed an irregular rhythm.
The device is standard equipment in hospitals and clinics for diagnosing heart conditions.
