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.
In these cases, M-mode echocardiography provides much information about the real-time relationships between the chamber walls that would be missed with external fetal heart rate monitoring.
There is no enough information about whether using physiologically more appropriate echocardiographic methods lead to different interpretations of longitudinal left ventricular systolic function than those derived from standard M-mode echocardiography in hypertensive patients.
Therefore, we think that early longitudinal left ventricular systolic dysfunction may be determined by use of strain and strain rate analysis despite other systolic parameters obtained from standard left ventricular M-mode echocardiography remain normal in never treated hypertensive patients.
