Quizplus · Accepted Answer

The rhythm in Figure 7 is a sinus rhythm as evidenced by the uniform P-wave morphology and PR interval. However, there is a non-conducted P wave indicated by the presence of a P-wave without a corresponding QRS complex. This suggests that the impulse did not make it through the AV node and did not initiate a ventricular contraction. This type of rhythm is referred to as a sinus rhythm with non-conducted PAC. There is no evidence of sinus arrest or junctional escape beat, sinus arrhythmia, or wandering atrial pacemaker.
