The presence of cannon A waves, the so called “frog sign”, has traditionally been considered diagnostic of atrioventricular nodal re-entrant tachycardia (AVNRT). Nevertheless, it has never been systematically evaluated. The aim of this study is to assess the independent diagnostic utility of cannon A waves in the differential diagnosis of supraventricular tachycardias (SVTs).

Upper turnaround point in a reentry circuit of the idiopathic left posterior fascicular ventricular tachycardia Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-27 Jongmin Hwang, Gi-Byoung Nam, June Hong Kim, Jun Kim, Kee-Joon Choi, You-Ho Kim
The anatomic extent of the reentry circuit in idiopathic left posterior fascicular ventricular tachycardia (LPF-VT) is yet to be fully elucidated. We hypothesized that entrainment mapping could be used to delineate the reentry circuit of an LPF-VT, especially including the upper turnaround point.

Incidence of cryoballoon expansion dislodgement during pulmonary vein isolation-an underappreciated frequent cause of incomplete isolation Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-23 Yu Liao, Emrie D. Tomaiko-Clark, Jake Martinez, Yasutoshi Shinoda, Michael F. Morris, Zhao Liu, Dalise Yi Shatz, Praneeth Katrapati, Naohiko Sahara, J. Peter Weiss, Michael S. Zawaneh, Roderick Tung, Rong Bai, Wilber Su
Cryoballoon ablation for atrial fibrillation (AF) requires adequate contact between the pulmonary vein (PV) antrum and cryoballoon. The surge of intraballoon pressure during the initial phase of ablation may change the balloon's shape and compliance, resulting in balloon dislodgement and loss of PV occlusion. Without continuous monitoring, this phenomenon is often undetected but can be associated with

Risk stratifier for sudden cardiac death beyond the left ventricular ejection fraction in Chagas cardiomyopathy Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-23 Roberto Coury Pedrosa, João Paulo do Vale Madeiro, Alex C. Alberto, Gabriel A. Limeira, Basílio de Bragança Pereira, Emília Matos do Nascimento, Fernando Soares Schlindwein, Gullien André Ng
Sudden cardiac death (SCD) risk markers are needed in Chagas cardiomyopathy (CC). Action potential duration restitution (APDR) dynamics is capable of extracting information on cardiac regional heterogeneity. This study intends to develop a patient-specific variables-based algorithm to predict SCD in the low-intermediate subgroups of the Rassi risk score.

Mapping of Purkinje-related ventricular arrhythmias by a multispline catheter with small and close-paired electrodes: Comparison with conventional catheters Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-19 Susumu Takase, Yasushi Mukai, Kazuhiro Nagaoka, Kiyohiro Ogawa, Shunsuke Kawai, Nobuhiro Honda, Tomomi Nagayama, Takeshi Tohyama, Shujiro Inoue, Kenji Sadamatsu, Hideki Tashiro, Kazuo Sakamoto, Tetsuya Matoba, Akiko Chishaki, Shintaro Kinugawa, Hiroyuki Tsutsui
Precise mapping of the Purkinje fiber network is essential in catheter ablation of Purkinje-related ventricular arrhythmias (PrVAs). We sought to evaluate the mapping ability of a multi-spline duodecapolar catheter (PentaRay) for PrVAs.

Clinical outcomes of left bundle branch area pacing: Prognosis and specific applications Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-19 Zhen Yang, Jiadong Liang, Ruizhe Chen, Naidong Pang, Nan Zhang, Min Guo, Jia Gao, Rui Wang
Cardiac pacing has become a widely accepted treatment strategy for bradyarrhythmia and heart failure. However, conventional right ventricular pacing (RVP) has been associated with electrical dyssynchrony, which may result in atrial fibrillation and heart failure. To achieve physiological pacing, Deshmukh et al. reported the first case of His bundle pacing (HBP) in 2000. This strategy was reported to

Two-incision versus three-incision implantation technique of subcutaneous implantable cardioverter defibrillator: Systematic review and meta-analysis of 2076 patients Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-10 Mohamed Hamouda Elkasaby, Basma Badrawy Khalefa, Mazen Negmeldin Aly Yassin, Malak Mohamed Abd El-Hameed, Omar Elkoumi, Hussam Al Hennawi
The implantable cardioverter-defibrillator (ICD) was designed to detect and treat ventricular arrhythmias, which account for nearly half of all cardiovascular fatalities. Transvenous ICD (TV-ICD) complications were reduced by introducing subcutaneous ICD (S-ICD). S-ICD can be implanted using a three (3IT)- or two (2IT)-incision technique. This systematic review and meta-analysis was conducted to compare

Beyond biventricular pacing: Exploring the advantages of his-bundle pacing and left bundle branch pacing in heart failure—A systematic review and meta-analysis Pacing Clin. Electrophysiol. (IF 1.8) Pub Date : 2023-12-09 Hussam Al Hennawi, Muhammad Khuzzaim Khan, Momina Khalid, Hiba Khalid, Laveeza Fatima, Muhammad Talal Ashraf, Sameer Bhimani, Behzad B. Pavri
This meta-analysis compares His-Purkinje system pacing (HPSP), a novel cardiac resynchronization therapy (CRT) technique that targets the intrinsic conduction system of the heart, with conventional biventricular pacing (BiVP) in heart failure (HF) patients with left ventricular (LV) dysfunction and dyssynchrony.
