Strain, Strain Rate, and the Force Frequency Relationship in Patients with and without Heart Failure
Abstract
BACKGROUND: The aim of this study was to examine the effect of heart rate (HR) on indices of deformation in adults with and without heart failure (HF) who underwent simultaneous high-fidelity catheterization of the left ventricle to describe the force-frequency relationship.
METHODS: Right atrial pacing to control HR and high-fidelity recordings of left ventricular (LV) pressure were used to inscribe the force-frequency relationship. …
