Active clinical trials for "Arrhythmias, Cardiac"

Evaluation of ventricular arrhythmias sensing via a left bundle branch area pacing lead.

Currently loop recorders diagnose arrhythmias and send automatic alerts to physicians based on R to R relationships only. We believe arrhythmia diagnostics could be improved if accurate detection of P and T waves as well as QRS complexes were possible. There is no technique available for long term outpatient monitoring of QT intervals for patient at risk of torsade de pointes when receiving QT prolonging drugs. We believe that if an accurate T wave detection algorithm were developed loop recorders could be used to monitor the QT interval, and perhaps even provide alerts for patients at risk. The objective of this study is to see if an algorithm can be developed to accurately define P and T waves using data from an implantable loop recorder.

Loss-of-function mutations in voltage-gated potassium channels cause long QT syndrome (LQTS) due to a prolonged cardiac repolarisation phase. Hypoteses: patients with loss-of-function mutations also exhibit altered hormone release upon glucose ingestion.

A Retrospective Propensity Matched Study comparing: real zero fluoroscopy catheter ablation conventional fluoroscopy catheter ablation without 3D system conventional fluoroscopy catheter ablation with 3D system

The purpose of this study is to obtain information on real-world device performance clinical assessments and clinical outcomes of patients receiving the Sleuth Implantable ECG Monitoring System.

This prospective multicenter registry study aims to determine whether device-detected sleep-disordered breathing events are associated increased risk of cardiac arrhythmias or other cardiovascular outcomes.

The aim of this study was to investigate the association between different reperfusion timing and ventricular arrhythmias (VAs) to provide evidence for clinical decision-making for patients with ST-segment elevation myocardial infarction (STEMI). All the participants included in the study were diagnosed with STEMI according to the 4th universal definition of myocardial infarction, with a follow-up of 1, 6, 12 months, respectively. Symptom onset-to-reperfusion timing (SO2RT) and 24h-dynamic electrocardiogram parameters were recorded to compare different SO2RT and VAs during 3 follow-up visits.

The purpose of this study is to determine if increasing the linear rise rate of injection of x-ray contrast in the heart during left ventriculograms(part of a cardiac Catheterization procedure) will decrease the incidence of arrythmias and improve image quality?
