1.
Right ventricular histological substrate and conduction delay in patients with Brugada syndrome
Ohkubo K, Watanabe I, Okumura Y, Takagi Y, Ashino S, Kofune M, et al.
Int Heart J . 2010 Feb; 51(1):17-23. PMID: 20145346
The reported pathogenesis of Brugada syndrome is phase 2 reentry resulting from shortening of the epicardial action potential duration at the right ventricular outflow tract (RVOT). However, several studies have...
2.
Combined effect of pulmonary vein isolation and ablation of cardiac autonomic nerves for atrial fibrillation
Ohkubo K, Watanabe I, Okumura Y, Ashino S, Kofune M, Takagi Y, et al.
Int Heart J . 2008 Dec; 49(6):661-70. PMID: 19075482
This study was designed to determine whether endocardial high-frequency stimulation at the pulmonary vein (PV) antrums can localize cardiac autonomic ganglionated plexi (GP) and whether ablation at these sites can...
3.
P wave morphology of an arrhythmogenic focus in patients with atrial fibrillation originating from a pulmonary vein or the superior vena cava
Ohkubo K, Watanabe I, Yamada T, Okumura Y, Hashimoto K, Ashino S, et al.
Circ J . 2008 Sep; 72(10):1650-7. PMID: 18758086
Background: It was hypothesized that atrial premature contractions (APCs) originating in the pulmonary veins (PVs) or superior vena cava (SVC) can be localized by evaluating characteristics of the P wave....
4.
Three-dimensional reconstruction of the coronary sinus with rotational angiography
Kofune M, Watanabe I, Ashino S, Okumura Y, Kawauchi K, Kofune T, et al.
Circ J . 2008 May; 72(6):1020-1. PMID: 18503233
Background: High-speed rotational coronary venous (CV) angiography (RCVA) permits dynamic, multi-angle visualization of the CV anatomy. Methods And Results: RCVA uses a rapid isocentric rotation over a 108 degrees arc,...
5.
Anatomic and electrophysiologic differences between chronic and paroxysmal atrial flutter: intracardiac echocardiographic analysis
Ohkubo K, Watanabe I, Okumura Y, Ashino S, Kofune M, Kawauchi K, et al.
Pacing Clin Electrophysiol . 2008 Apr; 31(4):432-7. PMID: 18373761
Background: It remains unknown why atrial flutter (AFL) occurs as either a chronic or paroxysmal arrhythmia. Purpose: The aim of the study was to compare intracardiac echocardiographic (ICE) images of...
6.
Full-motion two- and three-dimensional pulmonary vein imaging by intracardiac echocardiography after pulmonary vein isolation
Okumura Y, Watanabe I, Ohkubo K, Yamada T, Kawauchi K, Takagi Y, et al.
Pacing Clin Electrophysiol . 2008 Apr; 31(4):409-17. PMID: 18373758
Background: The pulmonary veins (PVs) are topographically complex and motile, so angiographic visualization of the PVs anatomy is limited. An imaging technique that accurately portrays the pulmonary vein (PV) anatomy...
7.
Radiofrequency catheter ablation of ventricular tachycardia originating in the left posterior and left anterior fascicles in a patient with prior myocardial infarction
Ashino S, Watanabe I, Kofune M, Okumura Y, Kawauchi K, Yamada T, et al.
Int Heart J . 2008 Mar; 49(1):119-27. PMID: 18360070
A 61-year-old man with prior anteroseptal myocardial infarction (ejection fraction: 40%) presented with recurrent episodes of palpitations. Twelve-lead ECG during palpitations showed an incessant ventricular tachycardia (VT1) with right bundle...
8.
Electrophysiological properties of the atrium after cardioversion of chronic atrial fibrillation: relation to the plasma brain natriuretic peptide level
Okumura Y, Watanabe I, Ashino S, Kofune M, Takagi Y, Kofune T, et al.
Int Heart J . 2007 Sep; 48(4):485-96. PMID: 17827820
Background: Brain natriuretic peptide (BNP) level has been shown to increase in patients with chronic atrial fibrillation (CAF) without overt heart failure (HF). Although atrial electrical remodeling associated with CAF...
9.
Electrocardiographic and electrophysiologic characteristics in patients with Brugada type electrocardiogram and inducible ventricular fibrillation: single center experience
Ohkubo K, Watanabe I, Takagi Y, Okumura Y, Ashino S, Kofune M, et al.
Circ J . 2007 Aug; 71(9):1437-41. PMID: 17721024
Background: The study examined the electrocardiographic and electrophysiologic characteristics in relation to programmed ventricular stimulation (PVS)-induced ventricular fibrillation (VF) in patients with Brugada syndrome. Methods And Results: Thirty-four patients with...

Endocardial electrograms from the right ventricular outflow tract after induced ventricular fibrillation in patients with Brugada syndrome
Ohkubo K, Watanabe I, Takagi Y, Okumura Y, Ashino S, Kofune M, et al.
Circ J . 2007 Jul; 71(8):1258-62. PMID: 17652891
Background: The pathogenesis of Brugada syndrome (BS) is reported to be phase 2 reentry resulting from shortening of the action potential duration at the epicardial site of the right ventricular...
