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: <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 - ✔-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 - ✔-1st 60-100 AV Node - ✔-2nd 40-60 Bundle of His - ✔-3rd 40-45 Right and Left Bundle Branches - ✔-4th 40-45 Purkinje Fibers - ✔-5th 20-50

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 AV Paced - ✔-Spike before P and before QR Failure to Capture - ✔-Spikes with no QRS Failure to Sense - ✔-Spikes happen regardless of QRS on their own How to determine the rhythm - ✔-Regular or irregular?

Rate?

P before every QRS? QRS for every P? QRS wide or narrow?

QT Interval - ✔-0.34-0.43 P Wave - ✔-0.06-0.12 sec PR Interval - ✔-0.12-0.20 sec SA Node Firing Rhythms - ✔-*Fires normally @ 60-100* -SR 60-100 -SB <60 -ST 100-150 -SVT 150-350 AV Node Firing, SA Node Failed Rhythms - ✔-*Fires normally @ 40-60* -Junctional rhythm 40-60 -Accelerated junctional rhythm 60-100 -Junctional tachycardia 100-150 Only Purkinje Fibers Firing Rhythms (Everything else has failed) - ✔-*Fires normally @ 20-50* -Idioventricular 20-50 -Accelerated idioventricular 50-100
