Intraoperative mapping is a method to document the surgical anatomy of cardiac tissues with electrophysiologic importance cartographically at time of surgery. The presented communication gives a survey of the present status of the technique of electrophysiologic mapping and its essential clinical applications. Special attention in this regard is directed to the intraoperative identification of the specialized AV conduction system in congenital cardiac malformations with unpredictable location of His bundle, to the detection of accessory AV bundles in patients with the Wolff-Parkinson-White syndrome and to the intraoperative morphological study of ventricular reentry tachycardias. Suitable technical equipment for "clinical" intraoperative electrophysiologic mapping is described in detail.

UI MeSH Term Description Entries
D007430 Intraoperative Care Patient care procedures performed during the operation that are ancillary to the actual surgery. It includes monitoring, fluid therapy, medication, transfusion, anesthesia, radiography, and laboratory tests. Care, Intraoperative
D011183 Postoperative Complications Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery. Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D004594 Electrophysiology The study of the generation and behavior of electrical charges in living organisms particularly the nervous system and the effects of electricity on living organisms.
D006327 Heart Block Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.

D006329 Heart Conduction System An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.

D013610 Tachycardia Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia. Tachyarrhythmia,Tachyarrhythmias,Tachycardias
D014927 Wolff-Parkinson-White Syndrome A form of ventricular pre-excitation characterized by a short PR interval and a long QRS interval with a delta wave. In this syndrome, atrial impulses are abnormally conducted to the HEART VENTRICLES via an ACCESSORY CONDUCTING PATHWAY that is located between the wall of the right or left atria and the ventricles, also known as a BUNDLE OF KENT. The inherited form can be caused by mutation of PRKAG2 gene encoding a gamma-2 regulatory subunit of AMP-activated protein kinase.
