unidimensional echocardiography

M-mode echocardiography

A form of echocardiography based on one-dimensional (“ice-pick”) analysis of the heart in motion. M-mode echocardiography was the first application of ultrasound in cardiology and continues to be used. It provides both high spatial and temporal (time-related) resolution, and is used to measure the thickness of the ventricular walls and the volumes of the cardiac chambers. It is of greatest use in diagnosing left ventricular hypertrophy or dysfunction, intracardiac tumours, pericardial effusion, and mitral valve stenosis or prolapse.
