Abstract Funding Acknowledgements Type of funding sources: None. Background Conduction system pacing (CSP), encompassing left bundle branch area (LBBAP) and His-bundle (HBP), is a novel strategy, which overcomes limitations conventional right ventricular pacing. Feasibility early safety both strategies have been established previously. While HBP mentioned as an alternative strategy in the lates...

The effects of alternating cycle lengths (bigeminal rhythm) on His-Purkinje system refractoriness were studied in 14 patients using His bundle and right bundle recordings. Programmed atrial stimulation at constant cycle length (method I) was scanned using the atrial extrastimulus technique (A2) and compared with an atrial cycle length of identical duration coupled to A2 on alternate beats (meth...

Electrophysiologic studies using the His bundle electrogram (HBE) and histologic studies of serial sections of the conduction system were correlated in two groups of deceased patients. Group 1 consisted of five patients with chronic complete atrioventricular block (CAVB) who had narrow QRS complexes and AH block (block proximal to the His bundle deflection). Group 2 consisted of four patients w...

Purpose To present a young female patient with left anterior orbital leiomyoma that originates from the supraorbital neurovascular bundle. Case presentation A 41-year-old female patient was admitted to our clinic with a complaint of swelling of the left upper eyelid. Based on the ophthalmological and imaging assessments, the excisional biopsy with the preliminary diagnosis of dermoid cyst was...
