Chamber Enlargement, and it is useful to be familiar with the terms applied to chamber enlargement on the EKG so that when these terms are used, either in written or verbal communication, the appearance of the tracing is accurately described and understood.

Axis, of the electrical event in question, which is atrial depolarization (P waves), ventricular depolarization (QRS complexes), and ventricular repolarization (T waves). Axis is not a vector—axis only has direction, while a vector has both direction and amplitude. The normal direction of all the axes is

Atrioventricular (AV) Block, of the PR interval beyond 0.2 s. The essential element of both second- and third-degree AV block is a “dropped beat,” in this case meaning an atrial depolarization (P wave) not followed by a ventricular depolarization (QRS complex). Second-degree AV block is subdivided into Mobitz I (or Wenckebach)

Chamber Enlargement,ctive value of the findings is disappointing. In spite of these limitations, the findings, when present, raise the possibility of chamber enlargement, and it is useful to be familiar with the terms applied to chamber enlargement on the EKG so that when these terms are used, either in written or verb

Pacemakers,ate atrial or ventricular depolarization. Timely pacemaker firing and successful initiation of the depolarization arc the sensing and capture functions to be assessed whenever a pacemaker is detected in an EKG.
