DYSRHYTHMIA AND ORAL SURGERY; II: JUNCTIONAL RHYTHMS

Abstract
Twenty-one patients have been monitored using oesophageal electrocardiography to determine the site of origin of eaopic rhythms occurring during oral surgery. It has been confirmed that in twelve patients these arose in the junctional system of the heart. One patient developed a bidirectional junctional tachycardia which is considered to be a dangerous dysrhythmia. The role of the cardiac sympathetic nerve supply in the production of these rhythms is discussed.
