Abstract: Ventricular arrhythmias closely correlates with stress.Not only individuals with organic heart diseases have a high risk of ventricular arrhythmias,healthy individuals are also susceptible to ventricular arrhythmias during stress.Electrophysiological characteristics of myocardium changes apparently during stress and electrical unstability of myocardium increases,which makes reentry and early afterdepolarization easy to happen.

Key words: stress, ventricular arrhythmias, sudden cardiac death, review
