# Left Ventricular Contractility Calculator

For the given filling pressure and systolic pressure, the performance of the ventricle is called as Left ventricular contractility. The Left ventricular contractility can be estimated by dP/dt ratio. Such ratio can be calculated using time interval between 1 and 3m/sec on MR velocity CW spectrum during isovolumetric contraction. Here is the online Left Ventricular Contractility calculator which helps you in the LV Contractility calculation in a simple manner.

For the given filling pressure and systolic pressure, the performance of the ventricle is called as Left ventricular contractility. The Left ventricular contractility can be estimated by dP/dt ratio. Such ratio can be calculated using time interval between 1 and 3m/sec on MR velocity CW spectrum during isovolumetric contraction. Here is the online Left Ventricular Contractility calculator which helps you in the LV Contractility calculation in a simple manner.

#### Formula:

L = (32 / T) × 1000 Where, L = Contractility Result T = Isovolumic Contraction(Interval between mitral valve closure and aortic valve opening)

### Example:

Calculate the Left Ventricular Contractility for the Isovolumic contraction of 40 m/s.

#### Solution:

LV Contractility = (32 / 40) × 1000
= 800-Abnormal mmHg/s.
