The objective of this clinical investigation is to evaluate the safety and efficacy of the CyberHeart System in patients with refractory ventricular tachycardia (VT). The ablation will be...
STereotactic Ablative Radiosurgery of recurrent Ventricular Tachycardia in structural heart disease (STAR-VT).
Sudden cardiac death is a frequent cause of cardiovascular mortality. Numerous rhythmic risk assessment criterion have been described targeting the substratum, the cardiac nervous tone or ...
The BERLIN VT study is designed to evaluate the impact of prophylactic ventricular tachycardia (VT) ablation on all-cause mortality and unplanned hospital admission for congestive heart fa...
To demonstrate that scar-based ventricular tachycardia (VT) ablation using the FlexAbility™ ablation catheter system results in a superior clinical outcome compared to routine drug thera...
Stereotactic body radiotherapy (SBRT) for ventricular tachycardias (VTs) could be an option after failed catheter ablation. In this study, we analysed the long-term efficacy and toxicity of SBRT appli...
The sympathetic nervous system plays an important role in arrhythmogenesis in arrhythmogenic right ventricular cardiomyopathy (ARVC). Sudden cardiac death commonly occurs during exertion and beta-bloc...
To raise awareness among pediatric intensive care specialists of catecholaminergic polymorphic ventricular tachycardia; an uncommon cause of polymorphic ventricular tachycardia and ventricular fibrill...
Catecholamingergic polymorphic ventricular tachycardia (CPVT) is characterized by adrenergically-induced VT, syncope, and sudden cardiac arrest (SCA). In the absence of structural disease, exercise-pr...
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.
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)
Implantable devices which continuously monitor the electrical activity of the heart and automatically detect and terminate ventricular tachycardia (TACHYCARDIA, VENTRICULAR) and VENTRICULAR FIBRILLATION. They consist of an impulse generator, batteries, and electrodes.
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).
An autosomal dominant defect of cardiac conduction that is characterized by an abnormal ST-segment in leads V1-V3 on the ELECTROCARDIOGRAM resembling a right BUNDLE-BRANCH BLOCK; high risk of VENTRICULAR TACHYCARDIA; or VENTRICULAR FIBRILLATION; SYNCOPAL EPISODE; and possible sudden death. This syndrome is linked to mutations of gene encoding the cardiac SODIUM CHANNEL alpha subunit.
