M-mode echocardiography


Also found in: Dictionary, Thesaurus, Encyclopedia.

M-mode

A diagnostic ultrasound presentation of the temporal changes in echoes in which the depth of echo-producing interfaces is displayed along one axis with time (T) along the second axis; motion (M) of the interfaces toward and away from the transducer is displayed.
Synonym(s): TM-mode

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.

Kleinman has found M-mode echocardiography to be particularly valuable since it traces cardiac chamber motion over time and permits detailed plotting of atrial versus ventricular activation in real time.
Another preferred method for assessing left ventricular diastolic function is the measurement of Vp by color M-mode echocardiography (34).
