Paroxysmal Complete Atrioventricular Block With Complete Left Bundle Branch Block Treated With Left Bundle Branch Area Pacing: A Case Report.

Clinical Engineering, Soseikai General Hospital, Kyoto, JPN.
Left bundle branch area pacing (LBBAP) can effectively enhance cardiac contraction by engaging the conduction system. LBBAP, compared with right ventricular apex pacing, can reduce QRS duration and enhance left ventricular function. Consequently, LBBAP has been proposed as a viable alternative to cardiac resynchronization therapy (CRT).

We report wide QRS complexes appearing in conjunction with prolonged R-R intervals in a 5- year old patient with situs ambiguous and mirror image dextrocardia, who had undergone ASD and VSD closure at of the age of one. We present differential diagnoses of intermittent spontaneous QRS widening and refer to ECG lead positioning in mirror image dextrocardia patients.

Accurate detection of cardiac arrhythmias is crucial for preventing premature deaths. The current study employs a dual-stage Discrete Wavelet Transform (DWT) and a median filter to eliminate noise from ECG signals. Subsequently, ECG signals are segmented, and QRS regions are extracted for further preprocessing.

Background: Transcatheter aortic valve replacement (TAVR) has revolutionized the management of aortic stenosis and has become the standard of care across a broad spectrum of patients with aortic stenosis. However, it is still associated with high incidence of conduction abnormalities, particularly new left bundle branch block (LBBB). Management of these patients remains a challenge.

Our study evaluated the efficacy and feasibility of left bundle branch area pacing (LBBAP) compared to right ventricular outflow tract septal pacing (RVOSP). We conducted a prospective, single-center, observational study involving 200 consecutive patients who required pacemaker implantation. The patients were divided into two groups (LBBAP and RVOSP), with 100 patients in each group.
