Which dysrhythmia has premature P waves with a different configuration than other P waves in the cardiac cycle? A. Atrial flutter B. Premature atrial complex C. First-degree atrioventricular block D. Second-degree atrioventricular block, type II - ** VERIFIED ANSWERS ** ✔✔ B. Premature atrial complexes are ectopic beats that are initiated by an irritable atrial focus. P waves are present, but because the ectopic focus originates the impulse outside the sinoatrial node, the premature P waves have a different configuration. Atrial flutter causes no P waves, but it causes flutter waves in a sawtoothed pattern. First-degree atrioventricular block has a P wave for every QRS complex, but the PR interval is consistently prolonged. Second-degree atrioventricular block, type II, has one or more P waves for every QRS complex. In first-degree atrioventricular block and second-degree atrioventricular block, type II, the P wave configuration is consistent from P wave to P wave Nutmeg toxicity is likely to cause which finding?

Defibrillation is the nonsynchronous delivery of energy to the heart during any phase of the cardiac cycle. The intent of this energy delivery is to simultaneously depolarize all of the heart cells, interrupting the abnormal electrical rhythm and allowing the sinoatrial node to resume its normal pacemaker activity. In synchronized cardioversion, energy delivery is timed to correspond with the QRS complex to avoid shock delivery during the relative refractory period, which can induce ventricular fibrillation. Transcutaneous and transvenous pacemakers electrically stimulate a heartbeat when the heart's intrinsic electrical system cannot generate a rate that is adequate to support cardiac output.
