EKG Exam 100+ Questions & Answers (2026) – Cardiac Rhythm Interpretation, Arrhythmias, Heart Blocks (CVT101) – AdventHealth University

This document provides a comprehensive collection of over 100 EKG exam questions with detailed and verified answers, focusing on cardiac rhythm interpretation and clinical cardiology concepts. It thoroughly covers key arrhythmias such as atrial fibrillation, atrial flutter, ventricular tachycardia, ventricular fibrillation, and asystole, along with heart blocks (1st, 2nd Type I & II, and 3rd degree), paced rhythms, and sinus rhythm variations. Each rhythm is explained using diagnostic criteria including rate, rhythm, P waves, PRI intervals, QRS duration, and clinical significance, making it highly effective for both understanding and application. In addition to rhythm identification, the document explores foundational concepts such as the cardiac conduction system (SA node, AV node, bundle branches), electrical impulse pathways, depolarization and repolarization, refractory periods, and ECG waveform interpretation. It also includes treatment approaches for stable and unstable patients, practical exam tips like rhythm differentiation shortcuts (e.g., TGIF for heart blocks), and recognition of life-threatening conditions such as ventricular fibrillation and pulseless electrical activity. This makes it a complete, high-yield study resource for mastering ECG interpretation. This material is ideal for students enrolled in Cardiovascular Technology (CVT101), Nursing (BSN), Emergency Medical Services (EMS), Paramedic Science, and Medical Assisting programs. It is particularly relevant for students at AdventHealth University and similar health science institutions, as well as professionals preparing for telemetry certification, EKG exams, or clinical competency assessments in cardiology and emergency care. The content aligns closely with widely used textbooks such as Rapid Interpretation of EKG’s by Dale Dubin and ECG Workout: Exercises in Arrhythmia Interpretation by Jane Huff, making it an excellent complementary study guide for reinforcing theoretical knowledge and improving rhythm recognition skills.
