Diagnostic Terms TermDefinition Cardiac catheterization (Catheter + Endoscope) the passage of a long tube into the heart chambers through a vein in an arm or leg, or neck. CatheterCatheter: An instrument that allows the collection of blood samples from different parts of the heart, and determines pressure differences in various chambers. EndoscopeEndoscope: long tube and optical system that allows you to see the inside of a hollow organ or cavity.

Diagnostic Terms Electrocardiography Echocardiograph The electrical currents of the heart muscle are recorded by an electrocardiograph. An echocardiograph is a record of the heart using ultrasonic waves through the chest waves. Positron Emission Tomography (PET)Used in other parts of the body but helps examine blood flow in the heart and blood vessels.
