Electrocardiographic manifestations: electrolyte abnormalities.
Because myocyte depolarization and repolarization depend on intra- and extracellular shifts in ion gradients, abnormal serum electrolyte levels can have profound effects on cardiac conduction and the electrocardiogram (EKG). Changes in extracellular potassium, calcium, and magnesium levels can change myocyte membrane potential gradients and alter the cardiac action potential. These changes can ...
متن کاملElectrocardiographic abnormalities in cerebrovascular accidents.
In order to assess the relationship of electrocardiographic (ECG) changes in acute cerebrovascular accidents (CVA) to the locations of the cerebral lesions, ECG records and brain computerized tomographic (CT) scans which were taken within 48 hours of CVA onset were examined in 39 patients without heart disease and/or treatment with cardiovascular drugs. The ECG was normal in 25% (3/12) of basal...
متن کاملEmetine toxicity with electrocardiographic abnormalities.
Seven case histories are presented illustrating various aspects of the noxious effects of emetine on the heart. T-wave changes, S-T segment deviations, and partial heart block are demonstrated. A case of frank myocardial infarction in a young man occurring during the administration of emetine is described. Finally, both persistence and lability of emetine-induced changes are illustrated. T OXIC...
متن کاملElectrocardiographic abnormalities in neurological diseases.
OBJECTIVE To evaluate electrocardiographic abnormalities in patients with neurologic diseases. METHODS We studied 161 patients with neurologic disorders by analyzing the 12-lead electrocardiogram during the pathological process. An expert who did not know anything about the patients evaluated the traces. RESULTS Neurological process included brain tumor (41%), stroke (27.3%), cerebral aneur...
متن کاملElectrocardiographic abnormalities in epidemic hepatitis.
Myocarditis has been reported in patients dying with viral hepatitis. With the increasing incidence of the disease, recognition of myocardial involvement is apparently important. The nature of the abnormalities suggested several factors including ischemia and local electrolyte disturbance of myo-cardium. The incidence of abnormalities was greater in the outpatients and in those with tachy-cardi...
