Bilateral Bundle-Branch Block
The electrocardiograms and salient clinical features of seven patients with electrocardiographic evidence of various types of bilateral bundle-branch block (BBBB) have been presented. When the complexes change in form and the P-R interval varies, the mechanisms are usually best interpreted by using the concepts of first degree, second degree, and third degree bundle-branch block with or without...
متن کاملParoxysmal Heart Block in Bundle Branch Block.
When a patient is suspected of having Stokes-Adams disease the electrocardiogram is of critical importance, particularly in respect of the auriculo-ventricular (A-V) conduction time. Should this not be prolonged, the possibility of paroxysmal heart block remains, although the diagnosis of Stokes-Adams disease is uncertain without some degree of heart block recorded graphically. It is not known ...
متن کاملVentricular Arrhythmia and Stokes - Adams Syndrome
An unusual case of ventricular arrhythmia is reported with electrocardiograms showing complete attacks of ventricular tachycardia, ventricular flutter and ventricular fibrillation. The etiology is unknown. Large doses of quinidine, to the point of toxicity, seemed to halt the arrhythmia but did not prevent its recurrence. Ephedrine was given with resulting immediate improvement and no recurrenc...
متن کاملPrednisone in the Treatment of Adams-stokes Attacks.
Adams-Stokes attacks are seen most frequently in patients with heart block. They are usually due to a temporary cardiac arrest not infrequently occurring when an incomplete heart block becomes complete, although a number of other irregularities may precipitate unconsciousness in these patients (Parkinson, Papp, and Evans, 1941). They occasionally occur in patients with bradycardia from other ca...
متن کاملAdams-Stokes syndrome caused by paroxysmal third-degree atrioventricular block.
Among I70 patients with Adams-Stokes syndrome, the majority had sinus rhythm between attacks. Clinical and electrocardiographic features of 67 patients in whom syncope was caused by paroxysmal third-degree atrioventricular block are discussed. The patients had normal pulse rates between attacks, their cerebral symptoms were usually not accompanied by cardiac symptoms, and 25 per cent had no sym...
