Filter by:The purpose of this study is to assess the performance and safety for the use of the investigational catheter for intracardiac mapping in the atria and ventricles.
A prospective sham-controlled randomized clinical trial to assess the effect of low-level tragus stimulation (LLTS) in patients with frequent premature ventricular complexes (PVCs)
The SWAF study will compare the performance of a smartwatch combined with Cardiologs Platform algorithm in the detection of Atrial Fibrillation and other arrhythmias with that measured on a manually read 12-lead ECG in subjects hospitalized for cardioversion or AF ablation.
To assess potential link between unrecognized myocardial inflammation (myocarditis) and premature ventricular contractions (PVCs) associated with and without reduced Left ventricular ejection fraction (LVEF) through comprehensive diagnostic work up.
The purpose of the present interdisciplinary research program is to develop and evaluate a disease-specific cognitive behavior therapy (CBT) protocol to increase quality of life (QoL) and reduce symptom burden in patients with Premature Ventricular Contractions (PVC).
This study aims to assess ECG changes for predicting ventricular arrhythmia in cardiomyopathic patients
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 standard of care to determine the optimal parameter setting in pacemapping.
Objective: investigators investigated the effects of metoprolol tartrate plus Tongmai Yangxin Pill on premature ventricular complexes and cardiac function in patients with premature ventricular complex. Methods: In total, 584 participants with premature ventricular complex will be randomly assigned (at a 1:1 ratio) into two groups: study group (metoprolol tartrate [25 mg twice per day, orally] plus Tongmai Yangxin Pill [40 pills twice per day, orally]) and control group (metoprolol tartrate [25 mg twice per day, orally] plus placebo [40 simulated pills twice per day, orally]). The total treatment period is 8 weeks. Efficacy endpoints and safety assessment: Primary efficacy endpoints are as follows: change in 24-h number of PVCs after treatment and effective rate of 24-h number of PVCs after treatment. Secondary efficacy endpoints are as follows: change in New York Heart Association classification; total effective rate of comprehensive effect; change in high-sensitivity C-reactive protein level; and change in echocardiography parameters (i.e., left ventricular ejection fraction, left ventricular end diastolic dimension, E/A, cardiac index, cardiac output, and stroke volume).
A multi-center, observational registry conducted in Europe and the UK to prospectively review VIVO in a clinical setting in 125 patients.
The purpose of this study is to assess the performance and safety for the use of the OPTRELL Catheter for intracardiac mapping in the atria and ventricles.
