Does Premature Ventricular Complex Impair Left Ventricular Diastolic Functions?

Anatolian Journal of Cardiology, 2023
Background: A higher frequency of premature ventricular complexes is associated with a higher risk of premature ventricular complex-induced cardiomyopathy. Although there are several studies on the systolic functions of the left ventricle in this patient

Analysis of left ventricular behaviour in diastole by means of finite element method [PDF]

, 1979
The human left ventricle in diastole can be modelled as a passive structure with incremental internal pressure change being considered as the load. Recent developments in engineering stress analysis provide techniques for predicting the behaviour of ...

The Stiffness of the Ascending Aorta Has a Direct Impact on Left Ventricular Function: An In Silico Model

Bioengineering
During systole, longitudinal shortening of the left ventricle (LV) displaces the aortic root toward the apex of the heart and stretches the ascending aorta (AA).
