This is a prospective, multi-site, non-randomized, data collection study. The purpose of this study is to investigate the correlation between pacing sites and ECG morphology or pacing parameters during left bundle branch pacing (LBBP) and perform the use condition analysis to assess the long-term performance of pacing lead during LBBP.
His bundle pacing (HBP) is a physiological pacing, but also has some limitations, including high and unstable pacing threshold in 5-10% patients, low R-wave amplitude causing inappropriate pacing management, damage to the His bundle during implantation. On the other hand, left bundle branch pacing (LBBP), achieved via trans-ventricular septal approach with the pacing lead tip at the left side of the ventricular septum, has recently initiated and been widely practiced in China because of easy implantation, relatively narrow paced QRS duration, low and stable pacing threshold, high R wave amplitude, and the LBBB correction by a low pacing output.
As LBBP is in the early phase of clinical practice in China, in order to better conduct LBBP implantation and understand mechanisms of LBBP therapy, physicians often do imaging assessment of the pacing lead in patients implanted with LBBP based on clinical necessity.
Additionally, there is no report of mid/long-term correlation between lead location and ventricular electrical activity, nor mid/long-term pacing lead performance assessment during LBBP.

In cardiac resynchronization therapy (CRT), biventricular pacing is performed by pacing the right ventricle (RV) and epicardium of the left ventricular (LV) postero-lateral wall. A signifi...
The purpose of this study is to determine, using echocardiography, whether bi-ventricular pacing improves the contractile force by resynchronizing both ventricles, thereby improving and/or...
The purpose of this study is to demonstrate that biventricular pacing (BiV) and left univentricular (left ventricular [LV] only) pacing are safe and effective for cardiac resynchronization...
A lot of questions about use of temporary transvenous pacing still remain obscure and there is no effective comparison between use of fluoroscopy versus electrocardiogram/echocardiogram in...
The SYNSEQ study intends to assess the positive left ventricular dP/dt max achieved by multipoint LV pacing (either simultaneously or sequentially) in comparison to the response achieved b...
Permanent His-bundle (HB) pacing is usually accompanied by simultaneous capture of the adjacent right ventricular (RV) myocardium-this is described as a non-selective (ns)-HB pacing. It is of clinical...
Pacing is an established and ubiquitous treatment of bradycardias and some types of heart failure. The optimal pacing lead position which maximises cardiac function and minimises deterioration of vent...
Regulation of the rate of contraction of the heart muscles by an artificial pacemaker.
The restoration of the sequential order of contraction and relaxation of the HEART ATRIA and HEART VENTRICLES by atrio-biventricular pacing.
Moving oneself through space while confused or otherwise cognitively impaired. Patterns include akathisia, exhibiting neuroleptic-induced pacing and restlessness; exit seekers who are often newly admitted institution residents who try to open locked exit doors; self-stimulators who perform other activities such as turning doorknobs, in addition to continuous pacing; and modelers who shadow other pacers.
Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.
