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...

The prophylactic value of parenterally administered bretylium tosylate against the onset of dysrhythmias after acute myocardial infarction has been assessed by a controlled trial in 101 male patients. Bretylium significantly reduced the incidence of supraventricular dysrhythmias but was without significant effect on the incidence of ventricular dysrhythmias. The only serious side-effect of the ...

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 wer...

An epidemiological study of filariasis in three villages along the coast at Matara has shown a prevalence of microfilaraemia of 4.4% and a geometric mean microfilaraemia density of 20.6 microfilariae/60ul of fingerprick blood. These are higher than previous values for the area. Prevalence is lower in females compared to males, and also in males under 20 years compared to the older males. Clinic...

Background Cardiac MRI (CMR) is increasingly being used clinically to assess patients with ventricular dysrhythmias. Structural heart disease such as non-compaction is associated with dysrhythmic risk. Recent literature has characterized the regional thickness of the compacted and trabeculated layers of the left ventricle (LV) in normal subjects but not in patients with ventricular dysrhythmias...
