Correct Answers: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 Answers: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 Answers: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 Answers: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 Answers:1st 60-100 AV Node - Correct Answers:2nd 40-60 Bundle of His - Correct Answers:3rd 40-45 Right and Left Bundle Branches - Correct Answers:4th 40-45 Purkinje Fibers - Correct Answers:5th 20-50 1 Small Box - Correct Answers:0.04 sec 1 Big Box - Correct Answers:0.20 sec Junctional Rhythms - Correct Answers:SA Node DID NOT FIRE AV Node fired NO P WAVE bc SA node didn't fire Narrow QRS P Wave - Correct Answers:Amplitude 0.5-2.5 mm Will be shorter than T wave Shows firing of SA node QRS - Correct Answers: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 Answers:1500/ # boxes R-R Calculate Irregular Rate - Correct Answers:# of Rs in 6 sec strip X 10 Unifocal PVCs - Correct Answers:Only 1 shape PVC Bigeminy - Correct Answers:PVC occurs every OTHER beat Trigeminy - Correct Answers:PVC occurs every THIRD beat Couplet - Correct Answers:2 PVCs together Triplet - Correct Answers:3 PVCs together Multifocal - Correct Answers:Multiple shapes Monomorphic V Tach - Correct Answers:Same Shapes V Tach Polymorphic V Tach - Correct Answers:Different Shapes V tach Coarse V Fib - Correct Answers:Chopy but not as high as polymorphic V tach Fine V Fib - Correct Answers:Fine and fibrillatory Idioventricular Rhythms - Correct Answers:Only purkinje fibers firing WIDE QRS always Atrially Paced - Correct Answers:Spike comes before P Ventricularly Paced - Correct Answers:Spike comes before QRS and QRS will be wide AV Paced - Correct Answers:Spike before P and before QR Failure to Capture - Correct Answers:Spikes with no QRS Failure to Sense - Correct Answers:Spikes happen regardless of QRS on their own How to determine the rhythm - Correct Answers:Regular or irregular? Rate? P before every QRS? QRS for every P? QRS wide or narrow?
