# Ventricular Contractility Assessment Calculator

The innate ability of the heart muscles to eject a stroke volume at a given prevailing afterload (arterial pressure) and preload (end-diastolic volume) is known as contractility. Enter the value of Isovolumic contraction in this Ventricular contractility assessment calculator to calculate Right Ventricle (RV) and Left Ventricle (LV) Contractility. For RV just divide 12 by Isovolumic Contraction and divide it by 1000 and for LV just divide 32 by Isovolumic Contraction and divide it by 1000.

Code to add this calci to your website  #### Formula:

R = (12 / T) × 1000 L = (32 / T) × 1000 Where, R = Contractility Result of Left Ventricle L = Contractility Result of Right Ventricle T = Isovolumic Contraction (Interval between mitral valve closure and aortic valve opening)

### Example:

Assess the Ventricular contractility with the Isovolumic contraction of 20 m/s.

#### Solution:

Right Ventricle Contractility = (12 / 20) × 1000
= 600 mmHg/s
Hence the Contractility rate of Right Ventricle is Normal
Left ventricle Contractility = (32 / 20) × 1000
= 1600 mmHg/s
Hence the Contractility rate of Left Ventricle is Normal
