SUMMARY A clinical, electrocardiographic, phonocardiographic, and arteriographic study was made of 20 normal subjects, 20 patients with right bundle-branch block (RBBB) and 20 patients with left bundle-branch block (LBBB). Ventricular asynchronism was documented in nearly all cases of bundle-branch block by the behavior of the arterial pulse and the heart sounds. The first heart sound was of no...

INTRODUCTION Atrial septal aneurysm (ASA) is often associated with other atrial septal abnormalities, particularly with atrial septal defect type ostium secundum or patent foramen ovale. ECG signs of incomplete or complete right bundle branch block are known to be associated with atrial septal defects, however such correlation with other atrial septal abnormalities is not documented. CASE PRE...

A method for the automatic classification of cardiopathies from an electrocardiogram (ECG) is presented in the paper. This treatment is based on an analysis of certain morphological parameters for the recognition of 4cardiopathies. The Hidden Markov Model (HMM) was used for parameter analysis and recognition of cardiac arrhythmias. The morphological parameters were divided into homogeneous grou...

Many investigators have dealt with the aspects of this problem. Both historical and contemporary registries and randomized clinical trials (RCTs) help us to understand the clinical relevance of BBB in the presence of an acute MI. The prevalence of BBB on arrival in patients with MI varies between 1.6 and 10.9%, without marked difference between RBBB and LBBB. The true incidence of BBBs of new o...

Tricyclic antidepressants (TCAs) may have dangerous cardiac effects in overdose. ECG is useful as both a screening tool for tricyclic antidepressant exposure and as a prognostic indicator. TCA overdose may produce various ECG changes. We report a case of Dothiepin overdose resulting in Brugada like pattern including RBBB which resolved spontaneously.

to explore the abnormalities in iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. body-fat percentage and resting 12-lead ecgs were recorded from all participants. of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. a total of 84% of the athletes demons...

His bundle electrograms (H) were recorded in 27 patients with PR prolongation and intraventricular conduction disturbances. The PR interval was subdivided into P-H (normal 80-140 msec), a measure of atrioventricular (A-V) conduction, and H-Q (normal 35-55 msec), a measure of intraventricular conduction. In 12 patients with left bundle-branch block (LBBB), P-H varied from 115-410 msec (mean 173 ...

Abstract Background Current ESC guidelines on management of acute myocardial infarction in patients presenting with ST-segment elevation (STEMI) recommend emergent invasive ischemic symptoms and bundle branch block (BBB). While left (LBBB) is a well-known high-risk feature infarction, data the diagnostic prognostic impact right (RBBB) comparison to LBBB context STEMI are scarce. Methods A prosp...
