Incomplete intraatrial block

Intra-atrial block is referred to as intra-atrial block. It refers to the prolongation or interruption of the impulses from the sinoatrial node in the atrium, which are divided into incomplete and complete conduction blocks. Incomplete atrial conduction block is caused by impulsive ectopic activation in the atrium, which invades the sinoatrial node during depolarization, making it impossible to pass down or delay the excitement.
