OBJECTIVE The aim of this study was to examine the usefulness of a portable Internet-enabled ECG recording system (iECG) in monitoring the heart health of Japanese individuals working abroad. METHODS This study included 24 male Japanese individuals working abroad, who had been found to have risks of cardiovascular diseases (CVDs) at periodic health checkups. The subjects were instructed to se...

everal investigators1-3 have recorded His bundle activity in patients with left axis deviation and right bundle branch block (RBBB), using the catheter method Scherlag et a1 described in 1969.4 According to the concepts of trifascicular conduct i ~ n , ~ conduction delay or block in the right bundle branch (RBB) and anterosuperior division of the left bundle branch (LBB) is responsible for this...

Fascicular tachycardia Fascicular tachycardia is uncommon and not usually associated with underlying structural heart disease. It originates from the region of the posterior fascicle (or occasionally the anterior fascicle) of the left bundle branch and is partly propagated by the His-Purkinje network. It therefore produces QRS complexes of relatively short duration (0.11-0.14 s). Consequently, ...

AIMS The Selvester QRS scoring system uses quantitative criteria from the standard 12-lead electrocardiogram (ECG) to estimate the myocardial scar size of patients, including those with left bundle branch block (LBBB). Automation of the scoring system could facilitate the clinical use of this technique which requires a set of multiple QRS patterns to be identified and measured. METHODS AND RE...

The direct-current magnetocardiogram not only shows the features usually seen on the electrocardiogram, but also shows the T-Q (baseline) shift due to cardiac injury current. The first direct-current magnetocardiogram measurements of the human heart are presented here. The hypothesis tested is that there is no injury current associated with the S-T shift seen in two electrocardiogram abnormalit...

Reentry within the His-Purkinje System (V3 phenomenon) where the reentry pathway incorporates both bundle branches and the bundle of His is a frequent phenomenon during ventricular refractory period studies. In this form of reentry, both divisions of the left bundle branch function as a single limb and the reentrant beats (V3) have either left bundle branch block or right bundle branch block pa...

The goal of this paper is to apply the universal gerbe developed in [CMi1] and [CMi2] and the local family index theorems to give a unified viewpoint on the known examples of geometrically interesting gerbes, including the determinant bundle gerbes in [CMMi1], the index gerbe in [L] for a family of Dirac operators on odd dimensional closed manifolds. We also discuss the associated gerbes for a ...

INTRODUCTION AND OBJECTIVES Left ventricular hypertrophy has important prognostic implications. Although electrocardiography is the technique most often recommended in the diagnosis of hypertrophy, its diagnostic accuracy is hampered in the presence of a left bundle branch block. METHODS In 1875 consecutive patients (56±16 years) undergoing studies to rule out heart disease and/or hypertensio...

The cases of two Asian brothers with idiopathic left ventricular tachycardia are reported. Their 12-electrocardial leads showed regular, wide QRS tachycardia showing left bundle branch block morphology with a superior axis deviation. Radiofrequency ablation was performed and there was no specific events during 10 year follow up.
