Normal sinus rhythm - ANSWERS-Regular Rate: 60- P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Bradycardia - ANSWERS-Regular Rate: < P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Tachycardia - ANSWERS-Regular Rate: 100- P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Premature Atrial Contraction - ANSWERS-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 - ANSWERS-IRREGULAR Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: <0.12 sec A fib RVR - ANSWERS-IRREGULAR Ventricular rate: 100- P wave: unable to see PR Interval: N/A QRS <0.12 sec Atrial Flutter - ANSWERS-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 - ANSWERS-Regular Rate: 150- P wave: Hidden in QRS or T wave PR: unable to determine QRS: <0.12 sec Junctional Rhythm - ANSWERS-Regular
QRS: WIDE and BIZARRE, >0.12 sec Ventricular Fibrillation - ANSWERS-Chaotic Coarse: big waves Fine: small waves Rate: unmeasurable P Wave: NONE PR Interval: N/A QRS: N/A Idioventricular - ANSWERS-Regular Rate: 20- P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec Accelerated Idoventricular Rhythm - ANSWERS-Regular Rate: 50- P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec 1st Degree AV Block - ANSWERS-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 - ANSWERS- 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 - ANSWERS-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 3rd Degree AV Block - ANSWERS-Atrials and ventricles don't communicate Rate: regular atrial P wave: Present, upright No relationship between P waves and QRS PR Interval: VARIABLE
NO P WAVE bc SA node didn't fire Narrow QRS P Wave - ANSWERS-Amplitude 0.5-2.5 mm Will be shorter than T wave Shows firing of SA node QRS - 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 - ANSWERS-1500/ # boxes R-R Calculate Irregular Rate - ANSWERS-# of Rs in 6 sec strip X 10 Unifocal PVCs - ANSWERS-Only 1 shape PVC Bigeminy - ANSWERS-PVC occurs every OTHER beat Trigeminy - ANSWERS-PVC occurs every THIRD beat Couplet - ANSWERS-2 PVCs together Triplet - ANSWERS-3 PVCs together
Multifocal - ANSWERS-Multiple shapes Monomorphic V Tach - ANSWERS-Same Shapes V Tach Polymorphic V Tach - ANSWERS-Different Shapes V tach Coarse V Fib - ANSWERS-Chopy but not as high as polymorphic V tach Fine V Fib - ANSWERS-Fine and fibrillatory Idioventricular Rhythms - ANSWERS-Only purkinje fibers firing WIDE QRS always Atrially Paced - ANSWERS-Spike comes before P Ventricularly Paced - ANSWERS-Spike comes before QRS and QRS will be wide AV Paced - ANSWERS-Spike before P and before QR Failure to Capture - ANSWERS-Spikes with no QRS Failure to Sense - ANSWERS-Spikes happen regardless of QRS on their own How to determine the rhythm - ANSWERS-Regular or irregular? Rate?
