Evaluating physiology of a human heart during ventricular tachycardia: new insights of mechanical alterations via beat to beat strain analysis-case report.

Modern 4D echocardiography machines offer the possibility to visualize the entire heart simultaneously. Thus ventricular arrhythmias can be evaluated using off-line strain analysis. This technology allows new real-time insights into the human heart showing compensatory mechanisms to overcome stressful episodes, such as ventricular tachycardia.
