Cardiac Arrhythmias and Conduction Disorders: ECG Recognition and Emergency Management

In this episode, we explore the clinical identification and management of cardiac arrhythmias and conduction disturbances, equipping nurses with the skills needed to recognize rhythm changes and respond effectively. We’ll review how electrocardiogram (ECG) waveforms are used to distinguish normal sinus rhythms from potentially life-threatening conditions such as ventricular fibrillation. Treatment strategies are examined in depth, including antiarrhythmic medications, synchronized cardioversion, and rapid defibrillation during cardiac arrest. We’ll also discuss the function and nursing care associated with implantable devices, such as permanent pacemakers and implantable cardioverter defibrillators (ICDs). Throughout the episode, we emphasize the nurse’s role in maintaining hemodynamic stability, recognizing complications, managing device care, and initiating CPR when necessary. This episode provides a practical framework for protecting cardiac output and ensuring patient safety in both acute and chronic care settings.
