Bayes Syndrome – Correct Answer:
- Third degree interatrial block with paroxysmal supraventricular arrhythmias
Various degrees of interatrial blocks are identified as follows:
First degree interatrial block: P wave duration more than 120 milliseconds
Third degree interatrial block: Longer P wave duration with biphasic P waves in inferior leads
Second degree interatrial block: These abnormalities are seen transiently in same ECG (atrial aberrancy)
It may be noted that these abnormalities may occur with or without associated atrial enlargement detectable by imaging modalities.
