cardi(o)-

The heart.

[Greek kardia, heart.]

The medical study of the heart is cardiology, practised by a cardiologist; an electrocardiogram (Greek graphein, write), or ECG, is a record or display of a person's heartbeat, created by an electrocardiograph. Several adjectives relate to the heart as part of the wider body system; these include cardiovascular (Latin vasculum, a little vessel) for the heart and its blood vessels, cardiopulmonary (Latin pulmo, pulmon-, lung) for the heart and lungs, and cardiothoracic (Greek thōrax, chest) for the heart and chest. Outside medicine the most common compound is cardioid for a heart-shaped curve in mathematics.
