Summary: Current recommendations for pacemapping are based on expert opinion and animals models. Present study sought to evaluate the influence of different parameters of pacemapping on QRS morphology. Pacemapping is performed with different cycle length (fixed burst vs. coupling interval) and stimulation output (maximum output vs. threshold) and resulting QRS complexes are compared to clinical PVC and the...
Summary: Single-channel electrocardiograms (lead I of 12-lead surface ECG; 30 seconds) will be collected from subjects/patients at 11 clinical centers in Germany to train an Artificial Intelligence in the automatic diagnosis of regular and irregular heart rhythms. Heart rhythms of interest are normal sinus rhythm (SR), atrial fibrillation (AF), atrial premature beats (APBs), ventricular premature beats (VP...
Summary: This research will investigate the PPG signal morphology related to physiological and non- physiological changes in arrhythmia-related heart rate as well as the performance of the PPG-based features previously developed within the framework of the Mini-Holter study to discriminate between several cardiac arrhythmias. To this end, clinical data will be recorded on patients by using a wrist-based PP...
Summary: The purpose of this study is to evaluate the use of virtual reality (VR) technology as adjunct to routine anesthesia care for patients undergoing electrophysiology (EP) procedures.
Summary: This randomized control trial is designed to explore the effect of low-level tragus stimulation in patients with frequent premature ventricular contractions.
Summary: Retrospective registry will compare subjects who've undergone a mapping and/or ablation procedure for either ischemic ventricular tachycardia or premature ventricular contraction using an epicardial approach with either manual or remote magnetic navigation. Subjects will be compared with regards to safety, efficacy and mortality.
Summary: Frequent premature ventricular beats (PVBs) are common, negatively affects the quality of life for many patients, and can lead to impaired contractile function. Rule-out of structural heart disease is key in the assessment of PVBs. Cardiac MR has a high sensitivity for structural heart disease, but the diagnostic gain from this resource-demanding procedure in the work-up of patients with PVBs is u...
Summary: This prospective, pragmatic, randomized controlled trial aims to evaluate the efficacy and safety of transcutaneous acupoint electrical stimulation (TAES) for patients with frequent premature ventricular contractions (FPVCs). Ninety participants will be randomized to TAES group and sham-TAES group with the ratio of 1:1. They will receive TAES plus usual care or sham-TAES plus usual care for 6 week...
Summary: Patients with refractory ventricular extrasystoles or tachycardia not eligible for catheter ablation will receive single fraction stereotactic body radiation therapy (cardiac radiosurgery) with 25 Gy.~Investigators initiated this study to demonstrate that in at least 70% of the patients the planned cardiac radiosurgery may be performed without any interruption or treatment related interventional e...
Summary: The ECTOPIA trial is a randomized, multicenter, clinical trial to assess elimination of ventricular premature beats (VPB) with catheter ablation versus optimal anti-arrhythmic drugs (AAD) treatment with flecainide/verapamil or sotalol.
Summary: This is a prospective multi-center international registry. The objective of this registry is to collect prospective data on patients undergoing catheter ablation for Ventricular Tachycardia (VT) and Premature Ventricular Contractions (PVC). The registry will be used for clinical monitoring, research, and quality improvement purposes.
Summary: Pacemapping is an essential tool during ablation of idiopathic PVC and VT. Automated template matching has been shown to have a significant influence on PVC ablation procedures, but the PASO module of CARTO3 has not been studied in a randomized trial. The Aim of this study is to evaluate the additional benefit of PASO template matching on PVC ablation procedure with regard to procedural parameters...
