Epicardial unipolar mapping has not been thoroughly investigated in Brugada syndrome (BrS). To examine the characteristics of epicardial potentials BrS and investigate differences from overt cardiomyopathy. was performed 8 patients with 6 We J-wave amplitudes using recordings at delayed potential (DP) sites via bipolar recordings. The repolarization time (RT) around DP recording measured, maximum dispersion RT divided by distance defined as index (RTDI). baseline revealed significantly...
ABSTRACT Introduction An effective cardiac resynchronization therapy (CRT) algorithm classifies each left ventricular (LV) pace as or ineffective based on electrogram morphology. Loss of capture, latency, pseudo‐fusion during sinus rhythm, and rapid responses due to atrial fibrillation (AF) premature conductions (PVCs) are potential causes CRT pacing. However, little is known about the relationship between percentage pacing (%i‐CRT) response. Methods Results Among 136 consecutive recipients,...
Background: The effect of paced-QRS (p-QRS) duration on long-term outcomes is unclear, so we assessed the association between p-QRS and cardiac events.
Background Ventricular parasystole is strongly associated with ventricular fibrillation (VF) in patients non-ischaemic cardiomyopathy. However, the relationship between and cardiac sarcoidosis (CS) remains unclear. The purpose of this study was to examine prevalence CS. Methods This a retrospective observational 214 consecutive diagnosed CS (mean age: 69±12 years, 104 males, median follow-up period: 6.8 years (IQR: 3.2–10.7) our centre. We investigated who developed arrhythmia (VA) using...
Abstract Cardiac accessory pathways (APs) in Wolff–Parkinson–White (WPW) syndrome are conventionally diagnosed with decision tree algorithms; however, there problems clinical usage. We assessed the efficacy of artificial intelligence model using electrocardiography (ECG) and chest X-rays to identify location APs. retrospectively used ECG analyse 206 patients WPW syndrome. Each AP was defined by an electrophysiological study divided into four classifications. developed a deep learning...
The prognosis and later fatal arrhythmia in cardiac sarcoidosis (CS) with relatively preserved function were unclear.This study aimed to evaluate the arrhythmic events patients CS mildly impaired function.Data collected from a nationwide Japanese cohort survey conducted 57 hospitals (n = 420); 322 left ventricular ejection fraction (LVEF) >35% investigated.Ventricular tachycardia (VT) manifestation was present 50 (16%) absent 272 (84%), of whom 36 (72%) 46 (17%), respectively, had an...
Abstract Introduction Infection is one of the most important complications associated with cardiac implantable electronic device (CIED) therapy. The number reports comparing outcomes transvenous lead extraction (TLE), surgical extraction, and conservative treatment for CIED infections using a real‐world database limited. This study investigated association between strategies their outcomes. Methods We performed retrospective analysis 3605 patients admitted to 681 hospitals nationwide...
Patients who achieve improved left ventricular ejection fraction (LVEF >35%) with cardiac resynchronization therapy (CRT) are at a lower risk of arrhythmia (VA). Little is known about the significance B-type natriuretic peptide (BNP) level for VA. This study investigated factors VA in CRT and stratification BNP LVEF.
To identify differences in patient characteristics, clinical practice and outcomes of cardiac implantable electronic device (CIED) therapy between Japan the USA. A cross-sectional study. Nationally representative administrative databases from USA containing hospitalisations with first-time implantations pacemakers, cardioverter-defibrillators (ICD) cardiac-resynchronisation or without defibrillators (CRTP/CRTD). Patients hospitalised CIEDs. In-hospital mortality, in-hospital complication...
Although the dynamic changes of atrial natriuretic peptide (ANP) expressions in a failing heart are well-documented, clinical implications detailed measurements each ANP molecular form processed from proANP remain unclear.Patients screening was conducted on patients who were eligible for cardiac resynchronization therapy (CRT) between 2014 and 2019 our institution. Blood samples echocardiographic parameters collected day before six months after implantation. Total ANP, proANP, N-terminal...
