TY - CHAP M1 - Book, Section TI - Mechanisms of Arrhythmias A1 - Zimmerman, Franklin H. PY - 2023 T2 - ECG Core Curriculum AB - It’s now time to begin our discussion of arrhythmias, one of the most important aspects of clinical electrocardiography. In the last chapter, we reviewed the fate of the normal sinus depolarization, using either a simple or expanded laddergram to illustrate passage of the impulse through the AV node and the remainder of the specialized conduction system until activating the ventricles (Figure 13-1). A cardiac arrhythmia may be defined as any disruption or aberration of this normal electrical sequence from start to finish.
