Abstract

Computer simulation is an important method for the basic researches of cardiac electrophysiology to prove the mechanisms and hypotheses of cardiac arrhythmias by reproducing body surface electrocardiograms. In this research, we extend the researches of heart models to the computer simulation of clinical electrophysiological study (EPS) as a clinical application of heart models. Through setting the standard EPS pacing protocols, including extrastimuli and incremental pacing in the heart models, we simulated the corresponding excitation propagations in the heart and the intracardiac electrograms that would be measured with catheter electrodes. Examples of complicated cases observed during EPS are reproduced in this research, including the induction of a Wenckebach pattern, the induction and termination of supraventricular tachycardia due to the reentry loop of antidromic atrioventricular reentrant tachycardia for the Wolff-Parkinson-White (WPW) syndrome (Type A), and the localization of an accessory pathway for the WPW syndrome (Type A). This study demonstrates an application of whole-heart modeling and computer simulation to clinical EPS.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Cardiac Electrophysiology

Cardiac electrophysiology is the study of electrical activities of the heart and includes the assessment, diagnosis, and treatment of cardiac events. Find the latest research on cardiac electrophysiology here.

Cardiac Conduction System

The cardiac conduction system is a specialized tract of myocardial cells responsible for maintaining normal cardiac rhythm. Discover the latest research on the cardiac conduction system here.
