Normally, this delay is consistent, but in Wenckebach, the delay increases with each successive heartbeat. Unlike pathological blocks, Wenckebach typically does not require aggressive treatment unless it is accompanied by significant symptoms like dizziness or low blood pressure.

Management focuses on monitoring and addressing underlying causes, such as adjusting medications that might be increasing vagal tone or slowing conduction. Eventually, the node fails to recover in time to conduct the next atrial impulse, resulting in a P wave that is not followed by a QRS complex.
For the asymptomatic patient, no treatment is typically required, as the phenomenon is often a normal physiological variation. In Type II block, the PR interval remains constant and regular before a sudden, unexpected drop of a beat, which indicates a more serious conduction problem below the AV node.

If symptoms such as syncope, fatigue, or near-fainting occur, however, further evaluation is warranted. Clinical Identification and Diagnosis Diagnosis relies heavily on the interpretation of an ECG, where the classic pattern is unmistakable.
