Precise determination of cardiac arrhythmias during open heart surgery by monitoring of myocardial electrograms

Monitoring and analysis of the cardiac rhythm during open heart surgery by the recording of multiple-lead epicardial electrograms is presented. The cardiac rhythm, the time relation between atrial and ventricular activation and the presence or absence of A-V conduction disturbances is always clearly...

Zusammenfassung:Monitoring and analysis of the cardiac rhythm during open heart surgery by the recording of multiple-lead epicardial electrograms is presented. The cardiac rhythm, the time relation between atrial and ventricular activation and the presence or absence of A-V conduction disturbances is always clearly delineated by the electrograms but frequently not by standard electrocardiographic tracings. The use of epicardial electrogram recordings offers an additional and highly accurate method for analysis of complex cardiac arrhythmias and determination of the functional state of the A-V conducting system. Further utilization of this technic should provide greater insight into arrhythmia analysis and allow a more physiologic approach to the treatment of disturbances of cardiac rhythm.
