HEART BLOCK AND THE SIMULATION OF BUNDLE BLOCK IN DIPHTHERIA

Heart Block and the Simulation of Bundle Block in Diphtheria.

Cardiographic studies in diphtheria show that a wide variety of arrhythmias and abnormalities of pattern occur. Among these heart block is familiar, not so much because it is common, but because in its more severe forms it indicates a grave prognosis. Burkhardt, Eggleston, and Smith (1938) recorded 11 cases of A-V dissociation, all fatal; some presented a terminal ventricular tachycardia. They ...

Paroxysmal 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 ...

Recovery from complete heart block in diphtheria.

prevalence of left bundle branch block & congestive heart failure

background: many factors influence the prognosis of patients with (chf), among these; more attention has been focused on the role of left bundle branch block (lbbb).  the present study was performed to find out the prevalence of chf in lbbb patients. methods: in this cross-sectional study, 246 were diagnosed consecutive patients with lbbb pattern in ecg during july 2004 until october 2006 at im...

Heart Block After His-Bundle Ablation

To investigate the electrophysiological properties of ventricular impulse formation after His-bundle ablation in 11 patients, incremental ventricular overdrive stimulation studies were performed. The studies, which were spread over a follow-up period of up to 601 days, were carried out invasively with temporary leads as well as noninvasively with the implanted pacemakers and chest wall inhibiti...
