OBJECTIVE To compare the efficacy and safety of nifekalant, a pure class III anti-arrhythmic drug, and lidocaine in patients with shock-resistant in-hospital ventricular fibrillation (VF) or ventricular tachycardia (VT). PATIENTS AND METHODS Between August 2005 and March 2008, we conducted a prospective, two-arm, cluster observational study, in which(More)
We report the case of 67-year-old man with Brugada syndrome, in whom daily episodes of ventricular fibrillation (VF) occurred every early morning for 4 days. The episodes of VF were completely prevented by an oral administration of cilostazol, a phosphodiesterase inhibitor. This effect was confirmed by the on-and-off challenge test, in which discontinuation(More)
Long QT syndrome (LQTS) is an inherited disease involving mutations in the genes encoding a number of cardiac ion channels and a membrane adaptor protein. Among the genes that are responsible for LQTS, KCNE1 and KCNE2 are members of the KCNE family of genes, and function as ancillary subunits of Kv channels. The third KCNE gene, KCNE3, is expressed in(More)
Focal nodular hyperplasia (FNH) of the liver is a rare benign lesion that probably reflects a local hyperplastic response of hepatocytes to a vascular abnormality. Currently, the natural history of the disease remains largely unknown. We present a patient with FNH of the liver who was followed up for 4 years. A 22-year-old woman with a 3-year history of(More)
We report a case of severe hypertrophic obstructive cardiomyopahy (HOCM) that was markedly improved by left ventricular (LV) apex epicardial pacing. A 55-year-old woman with HOCM had suffered from dyspnea. Cardiac catheter examination showed a resting pressure gradient across the LV outflow tract of 198 mmHg despite combined medication. During the(More)
BACKGROUND Effective alternatives to surgical myectomy for patients with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) remain unestablished. Dual-chamber (DDD) pacing was evaluated in these patients using right atrial (RA) and epicardial left ventricular (LV) leads. METHODS AND RESULTS In 6 patients with HOCM refractory to medical therapy and(More)
The number of implanted cardiac devices has been growing steadily over the last several years. Systems to monitor device data remotely have been introduced with the goal of reducing follow-up burden for both patients and physicians. Since the introduction of telemedicine depends greatly on the situations that are unique to each country, the acceptance of(More)
AIMS An electrical short circuit is a rare complication in a high-voltage implantable cardioverter-defibrillator (ICD). However, the inability of an ICD to deliver appropriate shock therapy can be life-threatening. METHODS AND RESULTS During the last 2 years, four cases of serious complications related to an electrical short circuit have been reported in(More)
KinectFusion is able to build a 3D reconstruction in real time and provide a 3D model. KinectFusion uses Iterative Closest Point (ICP) algorithm for point cloud alignment from the each camera frame and estimates each camera pose. However, ICP algorithm has its limits and the camera poses lack in accuracy. We propose an alignment method which is not only(More)
In this paper, we will present methods for camera pose estimation for mixed and diminished reality visualization in FTV application. We first present Viewpoint Generative Learning (VGL) based on 3D scene model reconstructed using multiple cameras including RGB-D camera. In VGL, a database of feature descriptors is generated for the 3D scene model to make(More)
