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...
متن کاملSteroid-induced T Wave Changes in Heart Block.
Giant T waves have previously been described by several observers. In most instances this electrocardiographic pattern has been associated either with acute myocardial infarction (Levine and Brown, 1929; Wood and Wolferth, 1934) or recent complete heart block (Ippolito, Blier, and Fox, 1954; Szilagyi and Solomon, 1959), and a slow ventricular rate is believed to be an important, but not invaria...
متن کاملElectro-Cardiographic Changes in Rheumatism
THE baneful influence of rheumatic processes oni cardiac functioni has always been recognize(l as of paramount importance. Cardiac pathology is intimately concerned with the group of disease maniifestationis labelled 'acute rheumatism' or 'rheumatic fever.' It is anl old observationi that the more clhronic varieties of rheumatism, comprising the groups of osteo-arthritis, chronic rheumatoid art...
متن کاملChanges in the electro-oculogram potential level.
THE eyeball may be regarded as a small battery, with a positive pole in the cornea and a negative pole in the retina. The work of Fenn and Hursh (1937), Frangois, Verriest, and de Rouck (1957), and others, suggests that the corneo-retinal potential is associated primarily with the retinal receptors; Brindley (1956) has suggested that the resting potential of the lens may contribute to it, and i...
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 ...
