Filter by:This is a randomized, placebo controlled trial of Dantrolene (N= 84 participants) to demonstrate the feasibility of using I.V. dantrolene to study the effect of RyR2 inhibition on cardiac electrophysiology, hemodynamics and ventricular arrhythmia inducibility in patients with structural heart disease referred for VT ablation. The investigators will also explore the pharmacokinetic/pharmacodynamic relationship of I.V. dantrolene and it short-term effect on specific cardiac electrophysiologic and hemodynamic parameters.
S-ICD avoids the use intravascular leads and their associated risks, has been increasingly used for primary and secondary prevention of sudden death. The long-term safety and feasible of S-ICD system in Asian population with a smaller body size remain unclear. The investigators propose to perform a prospective study in Korean population to investigate the safety and feasibility of S-ICD for primary or secondary prevention of sudden cardiac death.
Risk prediction in in inherited heart rhythm conditions that may cause sudden cardiac arrest or death is difficult. Sometimes the risks may be low but the loss of life in an otherwise healthy young individual is catastrophic. Clinicians often treat to the extreme to prevent this and so often those at unknown risk for a serious cardiac event are treated with an implanted cardioverter defibrillator (ICD) to protect against sudden death even though the risk is low or unknown. ICDs them selves are not without adverse events such as needing battery replacements, mechanical complications, inappropriate shocks and body image and self esteem issues for the patient. This study will use an inject able monitor that is less invasive to monitor inherited heart rhythm patients long term to help gather long term heart rhythm data (3 years) on patients with an inherited heart rhythm that will help to detect symptoms of dangerous heart rhythms so that the appropriate care can be provided.
The aim of this single-center prospective randomized controlled trial is to assess the superiority of contact-force-(CF)-sensing-based approach compared to conventional (non-CF-sensing) approach in the catheter ablation of PSVTs, and to investigate the safety of open-irrigated, contact-force-sensing ablation catheters (used in a "non-irrigated" mode) in these procedures.
This study will evaluate the acute effect of one single bout of high intensity exercise on the tendency for ventricular arrhythmia.
This registry is performed for the long-term assessment of outcome, performance and residual safety aspects of the BIOMONITOR III and possible successors in a real-life clinical set-up. In addition, this registry is set up in a way that it may also be used as a platform for submodules to investigate additional scientific and regulatory aspects while minimizing the additional effort for the investigational sites and patients.
High-resolution, non-invasive electromechanical mapping in genotyped long-QT syndrome patients and healthy controls at baseline and during smart provocation.
NODE-303 was a multi-center, open label study to evaluate the safety of etripamil NS in participants with Paroxysmal Supraventricular Tachycardia (PSVT). Participants were provided with an ambulatory Cardiac Monitoring System (CMS) to help document PSVT episodes. The CMS was self-applied by the participant, when they felt the onset of PSVT symptoms. Participants self-administered etripamil NS if vagal maneuver was ineffective. After an episode of PSVT where study drug was administered, the participant returned to the investigative site and had the option to continue in NODE-303 and manage up to three subsequent episodes of PSVT with etripamil NS for a maximum of four episodes.
The purpose of the study is to determine the effect of aerobic interval training in patients with an implantable cardioverter defibrillator (ICD) on physical fitness, quality of life and the amount of serious ventricular arrhythmic events on short and long term.
Study of multimodal-imaging guided stereotactic body radiotherapy (SBRT) for ventricular tachycardia (VT) ablation.
