Right Ventricular Defibrillation Lead Select Site Study

This study will compare single coil right ventricular defibrillation leads for implanted cardioverter/defibrillators (ICDs) in the apical and high septal locations. It is hypothesized tha...

Cardioverter Defibrillator Replacement With Induction of Ventricular Fibrillation and Defibrillation Testing

The SIMPLE study was a large one, and lasted quite a few years due to its design as a randomized controlled trial and the follow up needed to reach an endpoint. The investigators aim to co...

DOuble SEquential External Defibrillation for Refractory VF

Despite significant advances in resuscitation efforts, there are some patients who remain in refractory ventricular fibrillation (VF) during out-of-hospital cardiac arrest. Double sequenti...

Effect of Right Ventricular Lead Position on Defibrillation Threshold

The purpose of this study is to determine how the position of the right ventricular (RV) coil of an implantable cardioverter defibrillator (apex versus septum) affects the defibrillation t...

High Low Biphasic Energy Defibrillation (HiLoBED)

This inhospital study aims to compare the efficacy of high-versus low-energy biphasic shocks in order to determine the optimal level for defibrillation. Time is the essence when attending ...

Placement of a Continuous Stellate Ganglion Block for Treatment of Refractory Ventricular Fibrillation in the Setting of Known Prinzmetal Angina During Pregnancy: A Case Report.

A patient with a history of Prinzmetal angina, refractory ventricular fibrillation, cardiac arrest with an implantable cardioverter-defibrillator, and obesity presented to the emergency department at ...

Defibrillation testing and clinical outcomes after implantable cardioverter defibrillator implantation in patients in atrial fibrillation at the time of implant: An analysis from the SIMPLE trial.

The Shockless IMPLant Evaluation (SIMPLE) showed that defibrillation testing (DT) at the time of implantable cardioverter defibrillator (ICD) implant did not improve shock efficacy or reduce mortality...

Treatment of ventricular arrhythmias: What's New?

Ventricular arrhythmias can present as asymptomatic premature ventricular complexes (PVCs) or non-sustained ventricular tachycardia (VT), symptomatic presentation of the former arrhythmias, or sustain...

Saving lives with public access defibrillation: A deadly game of hide and seek.

Early defibrillation is a critical link in the chain of survival. Public access defibrillation (PAD) programmes utilising automated external defibrillators (AEDs) aim to decrease the time-to-first-sho...

A novel tool to evaluate the implant position and predict defibrillation success of the subcutaneous implantable defibrillator: the PRAETORIAN score.

Suboptimal positioning of the subcutaneous implantable defibrillator (S-ICD) increases the defibrillation threshold and risk of conversion failure.

Medical and Biotech [MESH] Definitions

Cardiac electrical stimulators that apply brief high-voltage electroshocks to the HEART. These stimulators are used to restore normal rhythm and contractile function in hearts of patients who are experiencing VENTRICULAR FIBRILLATION or ventricular tachycardia (TACHYCARDIA, VENTRICULAR) that is not accompanied by a palpable PULSE. Some defibrillators may also be used to correct certain noncritical dysrhythmias (called synchronized defibrillation or CARDIOVERSION), using relatively low-level discharges synchronized to the patient's ECG waveform. (UMDNS, 2003)

A sudden CARDIAC ARRHYTHMIA (e.g., VENTRICULAR FIBRILLATION) caused by a blunt, non-penetrating impact to the precordial region of chest wall. Commotio cordis often results in sudden death without prompt cardiopulmonary defibrillation.

A potentially lethal cardiac arrhythmia characterized by an extremely rapid, hemodynamically unstable ventricular tachycardia (150-300 beats/min) with a large oscillating sine-wave appearance. If untreated, ventricular flutter typically progresses to VENTRICULAR FIBRILLATION.

Isoforms of MYOSIN TYPE II, specifically found in the ventricular muscle of the HEART. Defects in the genes encoding ventricular myosins result in FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.

An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).
