cardiograph
Cardiac rhythm tracer
A cardiograph is an instrument that records the mechanical activity of the heart, producing a visual trace of heartbeats.
The term often refers specifically to an electrocardiograph, which measures electrical impulses.
The resulting record is a cardiogram: The doctor studied the cardiograph output for irregularities.
