BACKGROUND Conduction abnormalities are involved in the pathogenesis of ventricular fibrillation (VF) in patients with Brugada syndrome (BrS). OBJECTIVE We investigated whether right ventricular apical pacing (RVAP) could enhance the conduction abnormality and predict the susceptibility to VF in patients with BrS. METHODS Twenty patients with BrS (n =(More)
We reported a surviving case of 6-year-old boy with pontine hematoma. He complained of headache as an initial symptom and developed progressively Foville's syndrome with impairments of the IX-XII cranial nerves. Although brainstem tumor was suspected initially using CT scan, MRI revealed the existence of hematoma in the ventromedial pons. During the first 4(More)
BACKGROUND This study aimed to clarify whether retrograde P-wave amplitude during tachycardia can be used to differentiate slow-slow form of atrioventricular nodal reentrant tachycardia (S/S-AVNRT) from atrioventricular reentrant tachycardia through a posteroseptal accessory pathway (PS-AVRT). METHODS Sixteen patients with S/S-AVNRT and 14 patients with(More)
Effects of an angiotensin II receptor blocker, irbesartan (IRB), on the development of atrial fibrosis and atrial fibrillation (AF) were assessed in a canine model of atrial tachycardia remodeling (ATR) with left ventricular dysfunction, together with its possible association with involvement of p53. Atrial tachypacing (400 bpm for 4 weeks) was used to(More)
INTRODUCTION Atrial conduction heterogeneity is associated with progression of atrial fibrillation (AF). However, the relationship between P-wave parameters representing atrial conduction heterogeneity and AF recurrence after catheter ablation (ABL) is still unclear. METHODS AND RESULTS Subjects of the study were 126 consecutive patients with AF (78(More)
