Relias Dysrhythmia Basic B EXAM STUDY GUIDE 2026/2027 COMPLETE QUESTIONS WITH VERIFIED CORRECT ANSWERS || 100% GUARANTEED PASS NEWEST VERSION Ventricular Fibrillation - ANSWER Chaotic Coarse: big waves Fine: small waves Rate: unmeasurable P Wave: NONE PR Interval: N/A QRS: N/A Multifocal - ANSWER Multiple shapes Monomorphic V Tach - ANSWER Same Shapes V Tach Polymorphic V Tach - ANSWER Different Shapes V tach Coarse V Fib - ANSWER Chopy but not as high as polymorphic V tach Fine V Fib - ANSWER Fine and fibrillatory Idioventricular Rhythms - ANSWER Only purkinje fibers firing WIDE QRS always Atrially Paced - ANSWER Spike comes before P Idioventricular - ANSWER Regular Rate: 20-50 P wave: NONE PR Interval: N/A QRS: WIDE, 0.12 sec P Wave - ANSWER Amplitude 0.5-2.5 mm Will be shorter than T wave Shows firing of SA node QRS - ANSWER 0.06-0.10 sec SHOULD BE 0.12 sec Wide QRS: delay in ventricular contraction, delay of conduction through bundle branches or purkinje fibers BUNDLE BRANCH BLOCK or BLOCK IN PURKINJE FIBERS (idioventricular) Calculate Regular Rate - ANSWER 1500/ # boxes R-R Calculate Irregular Rate - ANSWER # of Rs in 6 sec strip X 10 2nd Degree AV Block Type II - ANSWER Irregular or regular Rate: 60 P wave: Present, upright PR Interval: PR interval consistently LONGER like type 1 but then a QRS will drop QRS: 0.12 sec Husband stays late till 9 consistently, then wife goes out and doesn't come home 3rd Degree AV Block - ANSWER Atrials and ventricles don't communicate Rate: regular atrial P wave: Present, upright No relationship between P waves and QRS PR Interval: VARIABLE QRS: variable P-P ad R-R consistent but NO correlation Husband and wife live separate lives and don't communicate SA Node - ANSWER 1st 60-100 Normal sinus rhythm - ANSWER Regular Rate: 60-100 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: 0.12 sec Ventricular Tachycardia - ANSWER Regular Rate: 100 P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE, 0.12 sec AV Node - ANSWER 2nd 40-60 Bundle of His - ANSWER 3rd 40-45 Right and Left Bundle Branches - ANSWER 4th 40-45 Purkinje Fibers - ANSWER 5th 20-50 1 Small Box - ANSWER 0.04 sec 1 Big Box - ANSWER 0.20 sec Junctional Rhythms - ANSWER SA Node DID NOT FIRE AV Node fired NO P WAVE bc SA node didn't fire Narrow QRS Ventricularly Paced - ANSWER Spike comes before QRS and QRS will be wide AV Paced - ANSWER Spike before P and before QR Failure to Capture - ANSWER Spikes with no QRS Failure to Sense - ANSWER Spikes happen regardless of QRS on their own How to determine the rhythm - ANSWER Regular or irregular? Rate?
