Life threatening ventricular dysrhythmias:
نویسنده
چکیده
Cardiac arrhythmias following acute myocardial infarction are often fatal. Although commonly used antiarrhythmics are usually effective, some patients develop dysrhythmias that are refractory to these medications. This article discusses the use and contraindications of bretylium tosylate, a relatively new antiarrhythmic drug that has been shown to be effective in reversing dysrhythmias that were refractory to other drugs.

Sudden severe dysrhythmias during anaesthesia can be life- threatening for the patient. We describe a case in which ventricular dysrhythmias and severe bradycardia occurred during dissection and mobilization of the deep lobe of the parotid gland during total parotidectomy under general anaesthesia. We believe that these dysrhythmias were caused by a trigemino- vagal reflex similar to the oculoc...

Experimental evidence suggests a number of pathologic and electrophysiologic mechanisms that may help initiate ventricular arrhythmias accompanying myocardial ischemia and infarction. Early and late phase events are associated with reentry or an enhancement of focal mechanisms, or both. These can initiate ventricular tachycardia (VT) or ventricular fibrillation (VF), or both. The presence of di...
