Filter by:This study will evaluate the acute effect of one single bout of high intensity exercise on the tendency for ventricular arrhythmia.
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.
Cardiac resynchronization therapy reduces mortality in patients with systolic heart failure and left bundle branch block. Reduced biventricular pacing can lead to therapy failure. Most effective mortality reduction was seen with a BiV pacing above 98%. Reduced BiV pacing is a common phenomenon with potential impact on CRT-response and pts' prognosis. Frequent ventricular ectopy may be associated with attenuated benefit from CRT. The investigators sought to systematically assess the effect of ventricular arrhythmia treatment on BiV pacing.
The purpose of this study is to determine, among a large cohort of 300 consecutive patients with hypertrophic cardiomyopathy, if extended ambulatory monitoring using the iRhythm Technologies, Inc. Zio XT device results in identifying a greater burden of nonsustained ventricular tachyarrhythmia (nsVT) compared to current ACCF/AHA guideline recommended 48-hour monitoring.
Ventricular Tachycardia storm is a medical emergency characterized by three or more episodes of ventricular arrhythmia within 24 hours and associated with a significantly increased mortality and massive health resource utilization. Several therapies are utilized including sympathetic blockade (through deep sedation and beta blockers), antiarrhythmic drugs, implantable cardioverter defibrillator (ICD) reprograming where applicable, and catheter ablation. Despite standard intervention, mortality rates remain high and additional therapeutic options are actively being investigated. The overall objective of this proposal is to investigate whether transcutaneous magnetic stimulation designed to inhibit the left stellate ganglion can be used in this population. This is a single-center, randomized, sham-controlled trial to assess the efficacy of transcutaneous magnetic stimulation of the left stellate ganglion to treat patients with ventricular tachycardia storm.
The purpose of this study is to determine whether the use of domperidone is associated with an increased risk of serious cardiac events among postpartum women in the six months following delivery. The hypothesis is that the use of domperidone will be associated with an increased risk of serious cardiac events among postpartum women. The investigators will carry out separate population-based cohort studies using health care databases in five Canadian provinces. Women with live births will be eligible to enter the cohort. We will identify all women who start domperidone during the six months following delivery and match them to similar women who do not start domperidone, with all included women followed until the occurrence of an adverse cardiac event or for up to six months after delivery. The results from the separate sites will be combined to provide an overall assessment of the risk of serious cardiac events in users of domperidone.
The main aim is to evaluate the safety and efficacy of the iD-System™, One-handed Disposable Internal Defibrillation System The device is made for manual defibrillation during intra-thoracic procedure, by transferring a shock from a defibrillation device to the patient's heart, in combination with the iD-Electrode. The device will be used when the patient reaches a stage of ventricular fibrillation or rapid ventricular tachycardia during cardiac surgery.
The Ripple VT-1 Study is a prospective clinical trial that aims to investigate if catheter ablation of ventricular tachycardia in patients with ischaemic heart disease can be effectively performed using Ripple Mapping.
Sudden cardiac death (SCD) is one of the major causes of mortality in adults with congenital heart disease (ACHD). Risk stratification for sudden cardiac death in this patient group is challenging and at the current moment there are no clear guidelines on implantable cardioverter-defibrillator (ICD) implantation for primary prevention of SCD in this young patient population. The reason for this is the fact that this is a heterogenous group of patients and SCD is a relatively rare event. Because of this there have been no prospective studies on SCD in ACHD. However, multiple retrospective studies on ICD implantation in ACHD have shown that this treatment does appear to be effective. Researchers from the Academic Medical Center have identified several risk factors for sudden cardiac death. A risk score was created using this data, which has been validated in an internal and external cohort in a retrospective setting. The design of this study, including the conception of the risk score, its calculation method and validation will be published in an international scientific peer-reviewed journal. The hypothesis of this study is that the risk score accurately predicts the risk of sudden cardiac death.
