ANSWERS.
Normal sinus rhythm - ✔✔✔Regular Rate: 60- 100 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- 150 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- 175 P wave: unable to see PR Interval: N/A QRS <0.12 sec Atrial Flutter - ✔✔✔Usually REGULAR can be irregular Atrial rate: 250- 350 Ventricular rate: variable BUT < atrial rate P Wave: Flutter PR Interval: N/A QRS: <0.12 sec Supraventricular Tachycardia - ✔✔✔Regular Rate: 150- 350 P wave: Hidden in QRS or T wave PR: unable to determine QRS: <0.12 sec Junctional Rhythm - ✔✔✔Regular Rate: 40- 60 P Wave: ABSENT or INVERTED PR Interval: None or <0. QRS: <0.12 sec Accelerated Junctional Rhythm - ✔✔✔Regular
Idioventricular - ✔✔✔Regular Rate: 20- 50 P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec Accelerated Idoventricular Rhythm - ✔✔✔Regular Rate: 50- 100 P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec 1st Degree AV Block - ✔✔✔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 - ✔✔✔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 - ✔✔✔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 - ✔✔✔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
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?
