Relias Dysrhythmia Basic A with 55 questions and answers

Normal sinus rhythm - Regular Rate: 60- P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Bradycardia - Regular Rate: < P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Tachycardia - Regular Rate: 100- P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Premature Atrial Contraction - IRREGULAR Rate: depends on underlying rhythm P wave: Present or hidden in T wave PR Interval: 0.12-0.20 sec QRS: <0.12 sec

Atrial Fibrillation - IRREGULAR Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: <0.12 sec A fib RVR - IRREGULAR Ventricular rate: 100- P wave: unable to see PR Interval: N/A QRS <0.12 sec Atrial Flutter - Usually REGULAR can be irregular Atrial rate: 250- Ventricular rate: variable BUT < atrial rate P Wave: Flutter PR Interval: N/A QRS: <0.12 sec Supraventricular Tachycardia - Regular Rate: 150- P wave: Hidden in QRS or T wave PR: unable to determine

Ventricular Tachycardia - Regular Rate: > P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE, >0.12 sec Ventricular Fibrillation - Chaotic Coarse: big waves Fine: small waves Rate: unmeasurable P Wave: NONE PR Interval: N/A QRS: N/A Idioventricular - Regular Rate: 20- P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec Accelerated Idoventricular Rhythm - Regular Rate: 50- P wave: NONE PR Interval: N/A

QRS: WIDE, >0.12 sec 1st Degree AV Block - Regular Rate: 60- P Wave: Present, upright PR interval: >0.20 sec CONSISTENTLY LONG QRS: <0.12 sec Husband stays late till 9 consistently 2nd Degree AV Block Type I Mobitz, Wenckebach - IRREGULAR Rate: 60- P wave: Present, upright PR Interval: Progressively longer until drop (PR interval longer and longer until drop) QRS: <0.12 sec Husband stays late till 9, then 11, then 1, then doesn't come home at all 2nd Degree AV Block Type II - Irregular or regular Rate: < 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

1 Small Box - 0.04 sec 1 Big Box - 0.20 sec Junctional Rhythms - SA Node DID NOT FIRE AV Node fired NO P WAVE bc SA node didn't fire Narrow QRS P Wave - Amplitude 0.5-2.5 mm Will be shorter than T wave Shows firing of SA node QRS - 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 - 1500/ # boxes R-R Calculate Irregular Rate - # of Rs in 6 sec strip X 10 Unifocal PVCs - Only 1 shape PVC

Bigeminy - PVC occurs every OTHER beat Trigeminy - PVC occurs every THIRD beat Couplet - 2 PVCs together Triplet - 3 PVCs together Multifocal - Multiple shapes Monomorphic V Tach - Same Shapes V Tach Polymorphic V Tach - Different Shapes V tach Coarse V Fib - Chopy but not as high as polymorphic V tach Fine V Fib - Fine and fibrillatory Idioventricular Rhythms - Only purkinje fibers firing WIDE QRS always Atrially Paced - Spike comes before P Ventricularly Paced - Spike comes before QRS and QRS will be wide

Only Purkinje Fibers Firing Rhythms (Everything else has failed) - Fires normally @ 20-50

• -Junctional rhythm 40-
• -Accelerated junctional rhythm 60-
• -Junctional tachycardia 100-
• -Idioventricular 20-
• -Accelerated idioventricular 50-
