The process or technique of recording heart activity and function using a cardiagraph; the medical practice of heart recording.
From Greek 'kardia' (heart) + '-graphy' (the practice or art of writing/recording, from 'graphein'). The '-graphy' suffix denotes both the technique and the discipline, like 'photography' or 'biography.'
Every '-graphy' word is essentially about making information visible—cardiagraphy visualizes the invisible electrical storm inside your chest, transforming it into a pattern a human eye can understand and interpret.
