Cardiac Dysrhythmias Part 2 – 2025/2026 ACLS & ECG Mastery | 100+ Verified Q&A | Bradycardia, Tachycardia, VT/VF Arrest, Pacemakers, PEA, ACLS Algorithms, Torsades, Defibrillation

This premium-level study guide offers over 100 verified exam questions and expertly explained answers, based on the latest 2025/2026 ACLS treatment protocols, ideal for nursing, medical, and paramedic students mastering Cardiac Dysrhythmias – Part 2. Aligned with real-world Advanced Cardiovascular Life Support (ACLS) algorithms, this document breaks down critical cardiac rhythms, causes, treatments, and emergency interventions in clinical cardiac emergencies. Key coverage includes: Evaluation and treatment principles for dysrhythmias based on symptoms and cardiac output status Classification of rhythms: bradycardia, tachycardia (with/without pulse), pulseless arrest (VT/VF) Treatment strategies including oxygenation, ECG, pacing, vasopressors, antiarrhythmics (amiodarone, lidocaine), cardioversion, defibrillation Step-by-step management of stable and unstable tachycardia, with emphasis on wide vs. narrow QRS, SVT, and VT with a pulse Recognition and urgent treatment of Torsades de Pointes, including magnesium administration Deep dive into pacemakers: temporary, transcutaneous, epicardial, and permanent Pacemaker coding systems (e.g., VVIR, AAI, DDDR), failure modes (failure to sense/capture/pace), nursing management, and patient teaching Implantable cardioverter defibrillators (ICDs): indications, education, function, and safety precautions ACLS interventions for VF/VT, asystole, and PEA, including energy settings for shocks, medication dosages, airway management, and when to call for expert consultation Radiofrequency ablation, mapping, and post-procedural care for treating atrial dysrhythmias Recommended for: ACLS-certified providers (RNs, EMTs, Paramedics, ICU/ED clinicians) Nursing students (ADN/BSN/MSN) preparing for cardiac and advanced med-surg exams Cardiac step-down, telemetry, and critical care staff Medical students and residents in emergency or cardiology rotations Educators and clinical instructors developing ACLS-aligned materials Any healthcare provider requiring deep competency in rhythm interpretation and dysrhythmia management Packed with real-life clinical applications, evidence-based interventions, and tested ACLS knowledge, this is your go-to document for excelling in high-stakes cardiac care exams and scenarios.
