Case of Heart-block.

Hyperkalemia-induced complete heart block

Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...

Complete congenital heart block: A case of multilevel block

Introduction Congenital heart block (CHB) has long been associated with maternal anti-SSA/Ro antibodies. Injury to the conduction system is presumed to be a consequence of the transplacental passage of maternal IgG autoantibodies into the fetal circulation. Within the heart, a spectrum of phenotypes has been described, including structural defects, functional abnormalities, and electrical distu...

Case of Heart Block Following Coronary Thrombosis

MODERN graphic methods, more especially the portable electrocardiograph, have brought into prominenice the comparative frequency of coronary thrornbosis. The majority of cases have occurred in people over fifty, many of them having had a previous history of some cardiovascular change, especially a change associated with high blood-pressure. This age inci(lence is shown in a series of 145 cases ...

A Case of Incipient Heart-Block

Heart block following propofol: a case report.

We report two cases of ventricular arrest with persisting atrial activity in association with propofol anaesthesia. In both cases, anticholinergic agents corrected the arrhythmia. It is recommended that anticholinergic drugs be given routinely when propofol is used in association with vagal stimulants.
