WHAT IS LEFT VENTRICULAR SYSTOLIC FUNCTION? LV systolic function describes the contractility of the LV. Contractility of the myocardial fibers of the heart is described by the Frank–Starling relationship whereby increases in preload (left ventricular end diastolic pressure [LVEDP]) result in increased contractility.Echocardiographic assessment of left ventricular (LV) diastolic function is an integral part of the routine evaluation of patients presenting with symptoms of dyspnea or heart failure. Left ventricular (LV) dP/dtmax provides a sensitive measure of the acute hemodynamic response to cardiac resynchronization therapy (CRT) and can predict reverse remodeling on echocardiography. Its use to guide LV lead placement has been shown to improve outcomes in a multicenter randomized trial.
Maximal left ventricular (LV) pressure rise (LV dP/dt max), a classical marker of LV systolic function, requires LV catheterization, thus surrogate arterial pressure waveform measures have been proposed.Heart Left Ventricle dP-dt. The tension time index of the diaphragm (TTId) is a dimensionless product of the ratio of developed Pdi to maximal transdiaphragmatic pressure (Pdimax) and the ratio of the inspiratory time (Ti) to the respiratory cycle time (Ttot), also known as the “duty cycle.”. The assessment of left ventricular (LV) ejection fraction (EF) is essential to differentiate HF with reduced ejection fraction from HF with preserved EF and HF with mid-range EF, and therefore to guide proper therapies based on LVEF cut-off values.Ejection fraction is the fraction of the end-diastolic volume (EDV, i.e blood volume in the ventricle at the end of diastole) that is pumped out during systole.
