Normal sinus rhythm ANSWER : Regular Rate: 60- 100 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Bradycardia ANSWER : Regular Rate: < P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Sinus Tachycardia ANSWER : Regular Rate: 100- 150 P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec Premature Atrial Contraction ANSWER : 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 ANSWER : IRREGULAR Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: <0.12 sec A fib RVR ANSWER : IRREGULAR Ventricular rate: 100- 175 P wave: unable to see PR Interval: N/A QRS <0.12 sec Atrial Flutter ANSWER : 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
P Wave: NONE or INVERTED PR Interval: None or <0. QRS: <0.12 sec Premature Ventricular Contraction ANSWER : IRREGULAR Rate: refer to underlying rhythm P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE , >0.12 sec Ventricular Tachycardia ANSWER : Regular Rate: > P Wave: NONE PR Interval: N/A QRS: WIDE and BIZARRE, >0.12 sec Ventricular Fibrillation ANSWER : Chaotic Coarse: big waves Fine: small waves Rate: unmeasurable P Wave: NONE PR Interval: N/A QRS: N/A
Idioventricular ANSWER : Regular Rate: 20- 50 P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec Accelerated Idoventricular Rhythm ANSWER : Regular Rate: 50- 100 P wave: NONE PR Interval: N/A QRS: WIDE, >0.12 sec 1st Degree AV Block ANSWER : Regular Rate: 60- 100 P Wave: Present, upright PR interval: >0.20 sec CONSISTENTLY LONG QRS: <0.12 sec
3rd Degree AV Block 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 ANSWER : 1st 60 - 100 AV Node ANSWER : 2nd 40 - 60 Bundle of His ANSWER : 3rd 40 - 45
Right and Left Bundle Branches ANSWER : 4th 40 - 45 Purkinje Fibers ANSWER : 5th 20 - 50 1 Small Box ANSWER : 0.04 sec 1 Big Box ANSWER : 0.20 sec Junctional Rhythms ANSWER : SA Node DID NOT FIRE AV Node fired NO P WAVE bc SA node didn't fire Narrow QRS P Wave ANSWER : Amplitude 0.5-2.5 mm Will be shorter than T wave Shows firing of SA node QRS 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 ANSWER : 1500/ # boxes R-R Calculate Irregular Rate ANSWER : # of Rs in 6 sec strip X 10 Unifocal PVCs ANSWER : Only 1 shape PVC
Coarse V Fib ANSWER : Chopy but not as high as polymorphic V tach Fine V Fib ANSWER : Fine and fibrillatory Idioventricular Rhythms ANSWER : Only purkinje fibers firing WIDE QRS always Atrially Paced ANSWER : Spike comes before P
Ventricularly Paced ANSWER : Spike comes before QRS and QRS will be wide AV Paced ANSWER : Spike before P and before QR Failure to Capture ANSWER : Spikes with no QRS Failure to Sense ANSWER : Spikes happen regardless of QRS on their own How to determine the rhythm ANSWER : Regular or irregular? Rate? P before every QRS? QRS for every P? QRS wide or narrow? QT Interval ANSWER : 0.34-0. P Wave ANSWER : 0.06-0.12 sec
