10 sec None: Absent Beginning of R wave to end of T wave Varies with HR. Normal: Less than half the R-R interval Occur in AV blocks. Occur in sinus arrest. 26 Copyright © 2005 F. A. Davis. 27 Component Pause QRS Complex grouping Notes: BASICS Characteristic Compensatory: Complete pause following a premature atrial contraction (PAC), premature junctional contraction (PJC), or premature ventricular contraction (PVC) Noncompensatory: Incomplete pause following a PAC, PJC, or PVC Bigeminy: Repeating pattern of normal complex followed by a premature complex Trigeminy: Repeating pattern of 2 normal complexes followed by a premature complex Quadrigeminy: Repeating pattern of 3 normal complexes followed by a premature complex Couplets: 2 Consecutive premature complexes Triplets: 3 Consecutive premature complexes Sinoatrial (SA) Node Arrhythmias Note: All ECG strips in this tab were recorded in lead II.

A. Davis. 35 ■ This form of WAP is associated with a ventricular response of Ͼ100 bpm. ■ MAT may be confused with atrial fibrillation (A-fib); however, MAT has a visible P wave. Premature Atrial Contraction (PAC) ■ A single complex occurs earlier than the next expected sinus complex. ■ After the PAC, sinus rhythm usually resumes. PAC ECGs Copyright © 2005 F. A. Davis. 10 sec) ♥ Clinical Tip: In patients with heart disease, frequent PACs may precede paroxysmal supraventricular tachycardia (PSVT), A-fib, or A-flutter.

After the dropped beat, cycles continue on time. 10 sec) ♥ Clinical Tip: Cardiac output may decrease, causing syncope or dizziness. ECGs Copyright © 2005 F. A. Davis. 33 Dropped beat X Atrial Arrhythmias ■ P Waves differ in appearance from sinus P waves. ■ QRS Complexes are of normal duration. Wandering Atrial Pacemaker (WAP) ECGs Copyright © 2005 F. A. Davis. 34 ■ Pacemaker site transfers from the SA node to other latent pacemaker sites in the atria and the AV junction and then moves back to the SA node.
