NCT05265520
The investigators aim to prospectively evaluate the efficacy and mechanism of benefit of His-bundle pacing enhanced cardiac resynchronization therapy (His-CRT) vs. cardiac resynchronization therapy (BIV-CRT) in patients with heart failure and right bundle branch block (RBBB).
NCT02441101
This clinical study has been designed to test whether a new pacing therapy would lead to improvement in heart function, symptoms and quality of life in a specific group of heart failure patients. This group has a unique electrical conduction problem (Right Bundle Branch Block) that did not respond well to the current available pacing therapy.
NCT04537455
Cardiac electrical mapping is an important tool that allows doctors to study the electrical activity of the heart in detail. Electrical mapping systems used in clinical practice are time consuming, invasive and very costly. Ultra-high frequency electrocardiography is a novel non-invasive cardiac mapping system. Ultra-high frequency electrocardiography (UHF-ECG) can be performed in 10-15 minutes without any risk or discomfort to patients. The aim of this study is to refine this mapping system, verify it against invasive mapping and develop software to bring this novel system into routine clinical use including predicting which patients will respond to cardiac resynchronisation therapy.
NCT05903313
"Chang Gung ECG Abnormality Detection Software" is a is an artificial intelligence medical signal analysis software that detect whether patients have abnormal ECG signals of 14 diseases by static 12-lead ECG. The 14 diseases were * Long QT syndrome * Sinus bradycardia * Sinus Tachycardia * Premature atrial complexes * Premature ventricular complexes * Atrial Flutter, Right bundle branch block * Left bundle branch block * Left Ventricular hypertrophy * Anterior wall Myocardial Infarction * Septal wall Myocardial Infarction * Lateral wall Myocardial Infarction * Inferior wall Myocardial Infarction * Posterior wall Myocardial Infarction The main purpose of this study is to verify whether "Chang Gung ECG Abnormality Detection Software" can correctly identify abnormal ECG signals among patients of 14 diseases. The interpretation standard is the consensus of 3 cardiologists. The results of the software analysis will be used to evaluate the performance of the primary and secondary evaluation indicators.
NCT05936294
This study will address whether acute adaptive RV pacing in sinus rhythm patients with severe LV systolic dysfunction and RBBB is superior to no ventricular pacing, and is as effective as echocardiographically optimized biventricular (BIV) pacing based on Medtronic ECG belt and cardiac performance as assessed by the echocardiographic parameters of RV and LV function.
NCT05889208
The goal of this clinical trial is to learn about the safety and outcome of prophylactic pacemaker implantation in patients with right bundle-branch block undergoing trans-catheter aortic valve (TAVI) implantation in patients with severe aortic stenosis and left ventricular ejection fraction.Participants will be randomized to: * Prophylactic pacemaker implantation prior TAVI * Conservative strategy
NCT04221763
The aim of this study is to compare the effectiveness of multiple modalities of cardiac resynchronisation therapy using high precision acute electrical and haemodynamic measurements.These modalities include biventricular pacing and conduction system pacing utilising His bundle and left bundle pacing. Conduction system pacing is a more physiological form of pacing. The study hypothesises that this will produce more effective cardiac resynchronisation.
