We describe a 66-year-old woman who had an alternating bundle branch block consisting of coexisting occurrence of right bundle branch block (RBBB) and left bundle branch block (LBBB) combined with Mobitz type II atrioventricular block (AVB). A prolonged PQ interval was associated with the RBBB pattern whereas it was not apparent in the LBBB pattern. Electrophysiologic study revealed that the LB...

Electrophysiological studies (His bundle recordings and atrial stimulation) were performed in nine patients who manifested periods of both right and left bundle branch block (RBBB and LBBB). In seven of the patients, alternating bundle branch block appeared to reflect intermittent or chronic bundle branch block superimposed on incomplete (but electrocardiographically complete) block of the cont...

Zygapophyseal (z) joints (or facet joints) are a potential source of pain in nearly 15-45% of patients suffering from chronic spinal pain. There are no clinical features or imaging techniques pathognomonic for z-joint pain. Blockade of the medial branch of the spinal nerve primary posterior ramus, using fluoroscopic guidance to ensure positioning of the needle tip and low volumes of local anest...

The management of patients with acute myocardial infarction complicated by bundle branch block is a significant clinical problem and represents 8% to 13% of patients with acute infarction. This study reviews the records of 606 patients with myocardial infarction admitted to our coronary care unit. Forty-seven (8%) had complete bundle branch block. The risk of developing high-degree AV block in ...

Branch Interventions for Facet Joint Syndrome: Potential Problems and Proposal of a Pericapsular Infiltration Technique Low back pain is a major health problem. Like any structure of the spine and its adjacent musculature, the facet joints can be a source of pain. It has been proposed that in 15%–52% of patients with chronic low back pain, the facet joints are involved, but isolated facet joint...

Electrocardiograms of 2500 consecutive patients who died in hospital were reviewed in order to study the relation ofcomplete left bundle-branch block to pathological determinants ofanatomical left ventricular hypertrophy. Of these, 43 patients demonstrated complete left bundle-branch block and all but two had anatomical left ventricular hypertrophy at necropsy. -Mean values of total heart weigh...

right bundle branch block (rbbb) is considered as an important predictor of poor outcome in patients with acute myocardial infarction, but the prognostic implication of rbbb in patients with suspected coronary artery disease (cad) is unclear. furthermore, the association between rbbb and incidence of cad also its influence on the severity of stenosis in coronary arteries has not been establishe...
