OBJECTIVE Compare in-hospital outcome in patients with ST-elevation myocardial infarction with right versus left bundle branch block. METHODS RENASICA II, a national Mexican registry enrolled 8098 patients with final diagnosis of acute coronary syndrome secondary to ischemic heart disease. In 4555 STEMI patients, 545 had bundle branch block, 318 (58.3%) with right and 225 patients with left (...
OBJECTIVES To conduct an overview (review-of-reviews) on pharmacological interventions for neck pain. SEARCH STRATEGY Computerized databases and grey literature were searched from 2006 to 2012. SELECTION CRITERIA Systematic reviews of randomized controlled trials (RCT) in adults with acute to chronic neck pain reporting effects of pharmacological interventions including injections on pain, ...
OBJECTIVE To compare the different effects of right ventricular pacing and classic left bundle branch block on left ventricular function. DESIGN Retrospective and prospective study of 48 patients by electrocardiography, and M mode, cross sectional, and Doppler echocardiography. SETTING A tertiary cardiac referral centre. PATIENTS 48 patients (age range 21 to 89 years, 15 women), 24 with a...
Lyme disease may present with a variety of cardiac manifestations ranging from first degree to third degree heart block. Cardiac involvement with Lyme disease may be asymptomatic, or symptomatic. Atrioventrical conduction abnormalities are the most common manifestation of Lyme carditis. Less common, are alternating right bundle branch block (RBBB) and left bundle branch block (LBBB). We present...
Multipoint 1 recording apparatus has been used to study the pattern of ventricular excitation in experimental bundle-branch block. After block, the wave of activation spreads uniformly from the contralateral ventricle across the septum to the free wall of the homolateral ventricle. Septal activation consumes more time than in the normal. Changes occur in the site and extent of early endocardia!...
