Correct Answer-Regular Rate: >100 P Wave: NONE or INVERTED PR Interval: None or <0.12 QRS: <0.12 sec Premature Ventricular Contraction - Correct Answer-IRREGULAR Rate: refer to underlying rhythm P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE , >0.12 sec Ventricular Tachycardia - Correct Answer-Regular Rate: >100 P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE, >0.12 sec Ventricular Fibrillation - Correct Answer-Chaotic Coarse: big waves Fine: small waves Rate: unmeasurable P Wave: NONE PR Interval: N/A QRS: N/A Idioventricular - Correct Answer-Regular Rate: 20-50 P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec Accelerated Idoventricular Rhythm - Correct Answer-Regular Rate: 50-100 P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec 1st Degree AV Block - Correct Answer-Regular Rate: 60-100 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 - Correct Answer-IRREGULAR Rate: 60-100 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 - Correct 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 - Correct 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 - Correct Answer-1st 60-100 AV Node - Correct Answer-2nd 40-60 Bundle of His - Correct Answer-3rd 40-45 Right and Left Bundle Branches - Correct Answer-4th 40-45 Purkinje Fibers - Correct Answer-5th 20-50 1 Small Box - Correct Answer-0.04 sec 1 Big Box - Correct Answer-0.20 sec Junctional Rhythms - Correct Answer-SA Node DID NOT FIRE AV Node fired NO P WAVE bc SA node didn't fire Narrow QRS P Wave - Correct Answer-Amplitude 0.5-2.5 mm Will be shorter than T wave Shows firing of SA node QRS - Correct 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 - Correct Answer-1500/ # boxes R-R Calculate Irregular Rate - Correct Answer-# of Rs in 6 sec strip X 10 Unifocal PVCs - Correct Answer-Only 1 shape PVC Bigeminy - Correct Answer-PVC occurs every OTHER beat Trigeminy - Correct Answer-PVC occurs every THIRD beat Couplet - Correct Answer-2 PVCs together Triplet - Correct Answer-3 PVCs together Multifocal - Correct Answer-Multiple shapes Monomorphic V Tach - Correct Answer-Same Shapes V Tach Polymorphic V Tach - Correct Answer-Different Shapes V tach Coarse V Fib - Correct Answer-Chopy but not as high as polymorphic V tach Fine V Fib - Correct Answer-Fine and fibrillatory Idioventricular Rhythms - Correct Answer-Only purkinje fibers firing WIDE QRS always Atrially Paced - Correct Answer-Spike comes before P Ventricularly Paced - Correct Answer-Spike comes before QRS and QRS will be wide AV Paced - Correct Answer-Spike before P and before QR Failure to Capture - Correct Answer-Spikes with no QRS Failure to Sense - Correct Answer-Spikes happen regardless of QRS on their own How to determine the rhythm - Correct Answer-Regular or irregular?
