Bundle branch reentrant ventricular tachycardia (VT) is a form of macroreentrant tachycardia. Although infrequent in occurrence, this arrhythmia presents with serious clinical manifestations and has potential for cure by catheter ablation. We report a case of bundle branch reentrant VT with ischemic source. Revascularization of culprit coronary artery was another means to treat VT. < The role of coronarography exploration in patients with bundle branch reentrant tachycardia and a history of coronary artery disease before right bundle branch ablation with risk of conduction disorders.>.

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.
