Comparative Study of Nifekalant Versus Amiodarone for Shock-Resistant Ventricular Fibrillation in Out-of-Hospital Cardiopulmonary Arrest Patients
Background: In Japan, intravenous nifekalant (NIF) was often used for direct current cardioversion-resistant ventricular fibrillation (VF), until the use of intravenous amiodarone (AMD) was approvedExpand

Analysis of right radial artery for transradial catheterization by quantitative angiography--anatomical consideration of optimal radial puncture point.
OBJECTIVES To determine the optimal radial puncture point, we analyzed the anatomy and luminal diameter of the right radial artery (RA) by quantitative angiography. BACKGROUND Difficulty of radialExpand

Angiographic evaluation of right upper-limb arterial anomalies: implications for transradial coronary interventions.
OBJECTIVES Upper-limb arterial anomalies are sometimes encountered during transradial coronary procedures. These anomalies may contribute to procedural failure or to vascular complications, and are aExpand

Identification of high-risk Brugada syndrome patients by combined analysis of late potential and T-wave amplitude variability on ambulatory electrocardiograms.
BACKGROUND Risk stratification is important in the management of Brugada syndrome (BrS). Late potentials (LPs) and T-wave amplitude variability (TAV) in high-resolution ambulatory electrocardiographyExpand

Incidence of Positive Ventricular Late Potentials Differs in Postural Changes among Supine, Left, and Right Lateral Decubitus, and Prone and Sitting Positions in Brugada Syndrome
High‐risk patients with Brugada syndrome (BrS) have inherent late potential (LP) fluctuations that might be explained by autonomic activity, electrolyte abnormality, and body temperature changes.Expand

Longitudinal analysis of the depressive effects of intravenous amiodarone on depolarization and repolarization: a case report.
Intravenous amiodarone (AMD) induces multiple antiarrhythmic effects via blocking of Na(+), Ca(2+), and IKr channels, and beta receptors. A patient on chronic dialysis was administered AMD forExpand

Changes in arrhythmogenic properties and five‐year prognosis after carbon‐ion radiotherapy in patients with mediastinum cancer
Carbon‐ion irradiation of rabbit hearts has improved left ventricular conduction abnormalities through upregulation of gap junctions. However, to date, there has been no investigation on the effectExpand

Usefulness of Continuous 24-hour Ventricular Late Potential to Predict Prognosis in Patients with Heart Failure.
OBJECTIVES An estimated 50,000 patients have heart failure (HF) in Japan, and the left ventricular ejection fraction (LVEF) is the typical predictor of prognosis. The identification of a noninvasiveExpand

Atrial fibrillation induced by applying acetylcholine to subadventitial layer of pulmonary vein in normal canine heart.
OBJECTIVES We determined whether acetylcholine (Ach) application to the pulmonary vein (PV) wall could induce AF and clarified its mechanisms, and determined whether circumferential PV radiofrequencyExpand

Potential difficulty for accurate categorization of drug-eluting stent thrombosis without coronary angiography: unignorable involvement of the cases with new onset acute myocardial infarction
Very late stent thrombosis (VLST) is a major unresolved problem of drug-eluting stent (DES) implants. However, its actual incidence with respect to the distribution of DES-target vessel and accuracyExpand
