Background: The clinical outcomes of a novel antitachycardia pacing (ATP) algorithm-intrinsic ATP (iATP)-compared to conventional ATP (cATP) have yet to be fully elucidated.
Methods: This retrospective study analyzed 128 patients and 1962 ventricular tachycardia (VT) episodes treated with the iATP or the cATP at Kokura Memorial Hospital. Patients were categorized into two groups: the iATP group (23 patients, 182 episodes) and the cATP group (105 patients, 1780 episodes).
Background: Lesion formation during catheter ablation is influenced by the power, contact force (CF), time, and catheter stability. However, the influence of the irrigation effects on lesion formation remains unknown.
Methods: An ex vivo experiment using conductive gel was performed.
Introduction: The long-term performance of leadless pacemaker (LPM) has not been well evaluated.
Methods: Between September 2017 and January 2021, 929 consecutive patients who underwent pacemaker implantation were grouped according to the types of pacemakers: LPM (LPM group, = 368) and conventional pacemaker (PM group, = 561).
Results: The median follow-up duration was 1.
Background: The incidence, predictors, and clinical impact of lead break during transvenous lead extraction (TLE) were previously unknown.
Methods: We included consecutive patients who underwent TLE between September 2013 and July 2019 at our institute. Lead break during removal was defined as lead stretching and becoming misshapen, as assessed by fluoroscopy.
