Interatrial Block: A Virtual Pandemic Requiring Attention

Interatrial block (IAB) denotes a conduction delay between the two atria (P-wave duration ≥110 ms). Depending on the severity of the block, IAB can be partial or advanced. Even though several studies have reported a high prevalence of IAB, it still remains a diagnosis many neglect without any follow-up. The crisis in IAB is undramatic until predictable complications appear. Nevertheless, the da...

A rare cause of Bachmann interatrial block.

The Long Journey to Interatrial Block Discovery

To begin, I feel it is important to point out that before our publications on interatrial block starting in the mid-1970s, a number of papers had already discussed, with isolated cases or short series, different aspects of so-called blocks at atrial levels and specifically of interatrial or intraatrial block (IAB) [1-8], that is the topic that we will comment in this paper. Although there is so...

Second-Degree Interatrial Block in Hemodialysis Patients

Interatrial conduction delays manifest as a prolonged P-wave duration on surface ECG and the term interatrial block (IAB) has been coined. They are usually fixed, but cases of intermittent IAB have been described, suggesting functional conduction block at the Bachmann bundle region. We report 2 cases of patients on chronic hemodialysis therapy presenting with intermittent IAB.
