This clinical investigation is intended to demonstrate the safety and effectiveness of ventricular ablation therapy using the FlexAbility Sensor Enabled Ablation Catheter in patients with ...
The purpose of the study is to assess the effectiveness and safety of a new device called an Intramural Needle Ablation Catheter (INA catheter). The INA catheter is used for locating and ...
The purpose of this study is to demonstrate the technical feasibility of the SERF Catheter and SERF Cardiac Ablation System to eliminate or control ventricular tachycardia (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...
Idiopathic ventricular tachycardia: Frequent monomorphic premature ventricular contractions or non-sustained ventricular tachycardia without underlying structural heart disease is not a rare condition...
Right ventricular (RV)-scar related ventricular tachycardia (VT) is often due to arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) or cardiac sarcoidosis (CS), but some patients whose...
Recent advances have enabled noninvasive mapping of cardiac arrhythmias with electrocardiographic imaging and noninvasive delivery of precise ablative radiation with stereotactic body radiation therap...
Ablation in the left ventricle (LV) is associated with a risk of thromboembolism. There are limited data on the use of specific thromboembolic prophylaxis strategies post-ablation. We aimed to evaluat...
Effect of Baseline Antiarrhythmic Drug on Outcomes With Ablation in Ischemic Ventricular Tachycardia: A VANISH Substudy (Ventricular Tachycardia Ablation Versus Escalated Antiarrhythmic Drug Therapy in Ischemic Heart Disease).
The VANISH trial (Ventricular Tachycardia Ablation Versus Escalated Antiarrhythmic Drug Therapy in Ischemic Heart Disease) compared the effectiveness of escalated antiarrhythmic drug therapy to cathet...
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.
