The possible contribution of localized conduction delay and abnormal action potentials to ventricular fibrillation (VF) was studied by applying an anisotropic cardiac computer model to clinical cases of the Brugada-type electrocardiogram (ECG), which shows right bundle branch block (RBBB), a normal QT interval, ST-segment elevation, and late r' in leads V1(More)
AIM The vascular endothelium plays a key role in the pathophysiology of atherosclerosis. Flow-mediated dilation (FMD) is a novel way of assessing endothelial function. Cilostazol is a unique antiplatelet drug that also has the potential to improve endothelial function. The objective of this present study was to investigate the effects of cilosatzol on(More)
A 62-year-old woman with a history of pulmonary embolism and primary antiphospholipid syndrome (PAPS) with positivity for lupus anticoagulant was admitted to hospital with shortness of breath. A filter had been implanted in her inferior vena cava (IVC) 5 years previously. Emergency echocardiography revealed a lobulated, mobile echogenic mass on the(More)
The effect of early reperfusion on the time course of signal-averaged ECG was examined in 90 patients with myocardial infarction. Abnormal signal-averaged ECG disappeared more frequently (p < 0.05) and earlier in cases with early reperfusion than in those without. Serious arrhythmic events in the late phase (> 7 days) occurred in patients with abnormal(More)
In recent years, various kinds of time-varying spectral analysis which estimate the frequency content of a signal as a function of time have been proposed. Spectro-temporal mapping (STM) is one of such methods with elaborate modification of a simple fixed period analysis. Merits and demerits of this method in clinical application are described in this(More)
INTRODUCTION Intra-cardiac echocardiography (ICE) which has some benefits, can be used to obtain detailed anatomy of the heart chambers or large vessels, and the catheter positions, and it has been considered useful for improving the outcome of the ablation. In the present study, we performed pulmonary vein isolation (PVI) under real time monitoring of ICE(More)
We report a patient with selective short-term memory disturbance caused by a glioma in the left temporal-parietal lobe. The patient was a 40-year-old right-handed housewife who complained of difficulty in memorizing series of numbers. She was working as a car dealer. She was well until 6 months prior to the present admission when she noted a difficulty in(More)
The purposes of this study were to investigate whether heart failure (HF) with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) share echocardiographic predictors and elucidate E/(e' × s') that predicts major adverse cardiovascular events (MACE) independent of other echocardiographic parameters in each HF group.(More)
