Active clinical trials for "Tachycardia"

This study to is being conducted in India to determine the role of catheter-based ablation for ventricular tachycardia (VT) in post- heart attack patients who meet established guidelines for implantable cardiodefibrillator (ICD) implantation, but cannot afford it. These patients would be started on chronic Amiodarone therapy, which has been shown to be effective but can often lead to multiple side effects. Patients will therefore be randomized in an even proportion to either a) the control group, receiving chronic Amiodarone therapy, or the study group, undergoing catheter ablation of VT in addition to chronic Amiodarone therapy. This trial will serve as a representative model for the developing world.

The main purpose of this study is to determine the effects of controlling the heart rate of patients with septic shock using an intravenous medication called esmolol.

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 therapy in subjects with documented Monomorphic Ventricular Tachycardia [MMVT] (both ischemic and non-ischemic) while maintaining an acceptable safety profile.

The purpose of this study is to find out if Esmolol is a safe and effective alternative treatment compared to standard treatment using a long acting beta blocker drug, in controlling abnormal heart rate before, during and immediately after surgery.

The purpose of this study is to determine whether intravenous amiodarone has less cardiac significant adverse events compared to intravenous procainamide in the acute treatment of haemodynamically well tolerated wide QRS tachycardia, the majority of them of probably ventricular origen.

The primary objective of this study is to evaluate the safety of etripamil nasal spray (NS) 70 mg when self-administered by patients with an episode of Paroxysmal Supraventricular Tachycardia in an outpatient setting (i.e., without medical supervision).

The investigators will test whether breathing through an inspiratory resistance device will improve the ability to be upright and decrease heart rate increases on standing in patients with postural tachycardia syndrome.

To demonstrate that ablation with the Therapy Cool Path Duo cardiac ablation system can eliminate ischemic VT and that its use does not result in an unacceptable risk of serious adverse events.

The study purpose is to demonstrate that ventricular tachycardia (VT) ablation using the Niobe™ ES system results in superior outcomes compared to a manual approach in subjects with ischemic scar VT in a low ejection fraction population.

The purpose of this study is to determine whether catheter based ablation is better than conventional anti-arrhythmic drug (AAD) therapy for reducing recurrent shocks in patients with an implantable cardioverter defibrillator (ICD). The second purpose of the study is to determine the safety of catheter-based ablation and the effect on quality of life of patients. The study hypothesis is that catheter ablation is superior to AAD therapy in preventing recurrent ventricular arrhythmia in such subjects. This is a pilot trial which will provide data regarding recruitment potential and the feasibility of conducting a larger trial.
