METHOD AND APPARATUS FOR MEASURING HEART CONTRACTILITY

摘要

A Method for measuring heart contractility of a patient, in which a mechanical shear wave is propagated through the heart and observation of the propagation leads to determine a shear wave propagation parameter representative of the elasticity of the heart is disclosed. The value of the propagation parameter at the end of a systole is sampled, which leads to a parameter representative of the end systolic elastance.
