Which defect for the priority is to assess for findings of heart conduction disturbance?

Ventricular septal defect. While assessments for conduction disturbance should be included following repair of any defect, it is a priority for this condition. Aventricular septal defect is an abnormal opening between the right and left ventricles. The atrioventricular bundle (bundle of his), a part of the electrical conduction system of the heart, extends from the atrioventricular node along each side of the interventricular septum and then divides into right and left bundle branches. Surgical repair of a ventricular septal defect consists of a purse-string approach or a patch sewn over the opening. Either method involves manipulation of the ventricular septum, thereby increasing risk of interrupting the conduction pathway. Consequently, postoperative complications include conduction disturbances.
