Right Ventricle To the Editor: Dubin et al1 recently published their experience with electrical resynchronization of the failing right ventricle (RV) in patients with congenital heart disease (CHD) (6 of 7 with tetralogy of Fallot). The authors used temporary atrioventricular (AV) sequential pacing from 3 RV sites with a paced AV delay set to 90% of the spontaneous PR interval to alleviate the ...

BACKGROUND To assess the influence of electrocardiographic (ECG) pattern on prognosis and complications of patients hospitalized with acute pulmonary embolism (APE). METHODS We performed a retrospective analysis of 292 patients who had confirmed APE. There were 183 females and 109 males, the age range was 17 to 89 years, and the mean age was 65.4 ± 15.5 years. RESULTS In our study group, th...

Based on randomized controlled studies, cardiac resynchronization therapy (CRT) is currently indicated in patients with systolic heart failure of New York Heart Association (NYHA) functional class III and IV, left ventricular ejection fraction <35% and wide QRS (>120 ms). Most of the enrolled patients were in sinus rhythm, were not previously paced and had mainly LBBB. Thus, there are uncertain...

curs routinely in patients after open-heart surgery for tetralogy of Fallot (TF). To determine the etiology of the RBBB pattern, 14 patients with TF, seven with ventricular septal defects (VSD), and one with pulmonary stenosis (PS) were studied during and after cardiac surgery. Bipolar electrograms from 10 selected right ventricular epicardial sites were recorded simultaneously with an ECG. Rec...

introduction brugada syndrome (brs) is an autosomal-dominant inherited cardiac arrhythmia that occurs due to sodium channelopathy and increases sudden cardiac death due to episodes of polymorphic ventricular tachyarrhythmia. it is characterized by st-segment elevation in the right precordial leads and right bundle branch block (rbbb) pattern. we herewith present a case of brugada syndrome with ...

Objectives: To report a case with dynamic ST segment elevation suggestive of anteroseptal acute myocardial infarction (AMI) that proved to be bilateral pulmonary thromboembolism (PTE). Clinical Presentation and Intervention: A 50-year-old woman with syncope was transferred to the emergency department. Findings from the admission electrocardiogram were suggestive of anteroseptal AMI; however, co...

After long-term exploration, it has been well established for the mechanisms of electrocardiogram (ECG) in health monitoring of cardiovascular system. Within the frame of an intelligent home healthcare system, our research group is devoted to researching/developing various mobile health monitoring systems, including the smart ECG interpreter. Hence, in this paper, we introduce a fuzzy classifie...

Submit Manuscript | http://medcraveonline.com in 1992 by the Brugada brothers [1,2]. In 1992 it has originally been described as an autosomal-dominant inherited arrhythmic disorder defined by ST elevation with successive negative T wave without structural cardiac abnormalities in the right precordial leads [3]. In 1996, in the description of the cellular basis for the J-wave of the ECG by Yan a...

A case of a 51-year old male is presented. A left bundle branch block inferior axis tachycardia was manifest. At electrophysiological study this tachycardia was inducible and was ablated in the septal right ventricular outflow tract (RVOT). Two other tachycardias were identified both with right bundle branch block (RBBB) morphology raising the suspicion of diffuse pathology. Arrythmogenic right...
