Background: The availability of stored intracardiac electrograms from implantable defibrillators (ICDs) has facilitated the study of the mechanisms of ventricular tachyarrhythmia onset. This study ...

Serious ventricular arrhythmias due to carotid-sinus massage are extremely uncommon. Meredith and Beckwith 8 recorded 2 cases of transient ventricular tachycardia that followed its use. The first well ...

A 67-year-old man with acute anterolateral myocardial infarction had recurrent ventricular fibrillation that required insertion of temporary pacemaker. When a permanent pacemaker was inserted stable ...

Many people who have suffered a heart attack subsequently develop life-threatening complications like ventricular fibrillation. Now an international research team from the University of Freiburg's ...

Ventricular fibrillation is a cardiac arrhythmia in which the muscle in the lower chambers of the heart (the ventricles) contracts irregularly and rapidly. The ventricles quiver and are unable to ...

This ECG shows ventricular fibrillation. Disorganized wide QRS complexes of relatively low amiplitude are present at a rate of greater than 300 beats per minute. Note the sharp spikes intermittently ...

Pulseless ventricular tachycardia occurs when an abnormally rapid heart rate originating in the heart’s lower chambers makes a pulse undetectable. Emergency cardiac defibrillation is usually necessary ...

Although premature ventricular beats (PVBs) in young people and athletes are usually benign, they may rarely mark underlying heart disease and risk of sudden cardiac death during sport. This review ...
