This episode of Intermediate Med-Surg takes on Chapter 39 from Lewis’s Medical-Surgical Nursing, covering the essentials of dysrhythmias. We’ll walk through the cardiac conduction system, ECG interpretation, and how to recognize and respond to common heart rhythms like atrial fibrillation, ventricular tachycardia, and complete heart block. You’ll also get a breakdown of emergency interventions like cardioversion, defibrillation, pacemakers, and ablation therapy. This episode is a solid resource for understanding how abnormal rhythms affect perfusion and what nurses must do when every second counts.
