Echocardiographic imaging is ideally suited for the evaluation of cardiac mechanics
because of its intrinsically dynamic nature. Because for decades, echocardiography has …

Echocardiographic strain imaging, also known as deformation imaging, has been developed
as a means to objectively quantify regional myocardial function. First introduced as post …

Left ventricular (LV) twist or torsion represents the mean longitudinal gradient of the net
difference in clockwise and counterclockwise rotation of the LV apex and base, as viewed …

The electrocardiogram (ECG) has always been an important biomedical test to diagnose
cardiovascular diseases. Current approaches for ECG monitoring are based on body …

Objectives: We sought to examine the accuracy/consistency of a novel ultrasound speckle
tracking imaging (STI) method for left ventricular torsion (LVtor) measurement in comparison …

The myofiber geometry of the left ventricle (LV) changes gradually from a right-handed helix
in the subendocardium to a left-handed helix in the subepicardium. In this review, we …

Gyrocardiography (GCG) is a new non-invasive technique for assessing heart motions by
using a sensor of angular motion–gyroscope–attached to the skin of the chest. In this study …

BACKGROUND: The prevalence of primary (hereditary) hemochromatosis and secondary
iron overload (hemosiderosis) is reaching epidemic levels worldwide. Iron-overload leads to …

The Topol Solution gives you a complete print and multimedia package consisting of
Textbook of Cardiovascular Medicine, Third Edition, a DVD, and access to a wealth of online …

Background—The cascade of events by which early diastolic left ventricular (LV) filling
increases with exercise is not fully elucidated. Doppler tissue imaging (DTI) can detect …
