Ventricular fibrillation (VFib or VF) and ventricular tachycardia (v-tach or VT) are two types of heart arrhythmia that occur in the heart’s lower chambers called the ventricles. The ventricles ...

Pulseless ventricular tachycardia (VT) is an atypical heart rhythm that can cause chest pain, fainting, and cardiac arrest. Doctors treat it with cardiopulmonary resuscitation, defibrillators, and ...

In patients with heart failure with reduced ejection fraction (HFrEF) who have an implantable cardioverter-defibrillator (ICD), the use of digoxin may increase the risk of ventricular tachyarrhythmia ...

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 ...

Implantable cardioverter-defibrillators (ICDs) have transformed the management of patients at risk of sudden cardiac death by combining continuous rhythm monitoring with therapies that interrupt ...

“Defibrillation testing can be safely omitted after S-ICD implantation when guided by the PRAETORIAN score,” Knops concluded, ...

The first-of-its-kind Aurora EV-ICD system offers a single-device, single procedure with a lead placed outside of the heart and veins. The FDA has approved the Aurora Extravascular Implantable ...

Researchers used an electrophysiological computer model of the heart's electrical circuits to examine the effect of the applied voltage field in multiple fibrillation-defibrillation scenarios. They ...

It is well known that acting quickly in the event of a cardiac arrest is important, but what does a quick initial shock with a defibrillator mean exactly for patients' chances of survival? Researchers ...
