Various modalities of detecting and quantifying lv systolic function and dysfunction

1. Dr. Adnan Ali Khan
Assessment Of Left Ventricular
Systolic Function

2. Linear Measurements

3. Linear Measurements
 Measurements taken in M-Mode In PLAX view.
 Primitive method.
 Inferior in accuracy and quality to 2D measurements.
 Regional variations in LV shape and function in various
conditions could not be adjusted for causing under or over-
estimation of dysfunction.
 True minor axis is overestimated.
 Newer technologies provide the access to an ‘Anatomic M-
Mode’ which ameliorates this issue.

4. Linear Measurements

5. Indirect M-Mode Markers of Left
Ventricular Function
 Increased EPSS
 Systolic gradual
closure of Aortic
valve
 Reduced E wave
height
 Reduced ratio of
mitral
excursion to IVDd.
