ABSTRACT

The interatrial block is an auricular conduction abnormality secondary to delay or block through the Bachmann's bundle. Dr. Antonio Bayés de Luna was the first who provided a clear description of atrial conduction block in 1979, classifying them into either inter- and -intra atrial. The interatrial block is expressed in the electrocardiogram (ECG) by the presence of P-wave duration that equals or exceeds 120 mseg and presents usually a bimodal morphology, especially in leads I, II, aVL and inferior leads. There are different types of interatrial block related to deterioration of conduction between the right and left atrium. It was demonstrated that this type of block is very frequently accompanied by paroxysmal atrial arrhythmia, especially atrial fibrillation. Current medical therapies included anti-arrythmic, anticoagulation and in special cases atrial resynchronization. The aim of this paper is to emphasize the importance of the evaluation of P wave and interatrial blocks in the perioperative period.
