RELIAS ADVANCED DYSRHYTHMIA EXAM A QUESTIONS AND
ANSWERS LATEST UPDATE 2025|ALREADY GRADED A+
"Junctional Rhythms - CORRECT ANSWER=> SA Node DID NOT FIRE
AV Node fired NO P WAVE bc SA node didn't fire Narrow QRS"
"P Wave - CORRECT ANSWER=> Amplitude 0.5-2.5 mm
Will be shorter than T wave Shows firing of SA node"
"QRS - CORRECT 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 - CORRECT ANSWER=> 1500/ # boxes R-R"
"Calculate Irregular Rate - CORRECT ANSWER=> # of Rs in 6 sec strip X 10"
"Unifocal PVCs - CORRECT ANSWER=> Only 1 shape PVC"
"Bigeminy - CORRECT ANSWER=> PVC occurs every OTHER beat"
"Trigeminy - CORRECT ANSWER=> PVC occurs every THIRD beat"
"Couplet - CORRECT ANSWER=> 2 PVCs together"
"Triplet - CORRECT ANSWER=> 3 PVCs together"
"Multifocal - CORRECT ANSWER=> Multiple shapes"
"Monomorphic V Tach - CORRECT ANSWER=> Same Shapes V Tach"
"Polymorphic V Tach - CORRECT ANSWER=> Different Shapes V tach"
"Coarse V Fib - CORRECT ANSWER=> Chopy but not as high as polymorphic V tach"
"Fine V Fib - CORRECT ANSWER=> Fine and fibrillatory"
"Idioventricular Rhythms - CORRECT ANSWER=> Only purkinje fibers firing
WIDE QRS always"
"Atrially Paced - CORRECT ANSWER=> Spike comes before P"
"Atrial Fibrillation - CORRECT ANSWER=> IRREGULAR
Atrial rate: UNMEASURABLE Ventricular rate: variable P wave: unable to see PR Interval: N/A QRS: <0.12 sec"
"A fib RVR - CORRECT ANSWER=> IRREGULAR
Ventricular rate: 100- P wave: unable to see PR Interval: N/A QRS <0.12 sec"
"Atrial Flutter - CORRECT ANSWER=> 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 - CORRECT ANSWER=> Regular
Rate: 150- P wave: Hidden in QRS or T wave PR: unable to determine QRS: <0.12 sec"
"Junctional Rhythm - CORRECT ANSWER=> Regular
Rate: 40- P Wave: ABSENT or INVERTED PR Interval: None or <0. QRS: <0.12 sec"
"Accelerated Junctional Rhythm - CORRECT ANSWER=> Regular
Rate: 60- P Wave: NONE or INVERTED PR Interval: None or <0. QRS: <0.12 sec"
Husband stays late till 9 consistently"
"2nd Degree AV Block Type I Mobitz, Wenckebach - CORRECT ANSWER=> 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 - CORRECT ANSWER=> 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 - CORRECT 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 - CORRECT ANSWER=> 1st
"AV Node - CORRECT ANSWER=> 2nd
"Bundle of His - CORRECT ANSWER=> 3rd
"Right and Left Bundle Branches - CORRECT ANSWER=> 4th
"Purkinje Fibers - CORRECT ANSWER=> 5th
"1 Small Box - CORRECT ANSWER=> 0.04 sec"
"1 Big Box - CORRECT ANSWER=> 0.20 sec"
"Ventricularly Paced - CORRECT ANSWER=> Spike comes before QRS and QRS will be wide"
"AV Paced - CORRECT ANSWER=> Spike before P and before QR"
"Failure to Capture - CORRECT ANSWER=> Spikes with no QRS"
"Failure to Sense - CORRECT ANSWER=> Spikes happen regardless of QRS on their own"
"How to determine the rhythm - CORRECT ANSWER=> Regular or irregular?
Rate? P before every QRS? QRS for every P? QRS wide or narrow?"
"QT Interval - CORRECT ANSWER=> 0.34-0.43"
"P Wave - CORRECT ANSWER=> 0.06-0.12 sec"
"PR Interval - CORRECT ANSWER=> 0.12-0.20 sec"
"SA Node Firing Rhythms - CORRECT ANSWER=> Fires normally @ 60-100
-SR 60-
-SB <
-ST 100-
-SVT 150-350"
"AV Node Firing, SA Node Failed Rhythms - CORRECT ANSWER=> Fires normally @ 40-60
-Junctional rhythm 40- -Accelerated junctional rhythm 60- -Junctional tachycardia 100-150"
"Only Purkinje Fibers Firing Rhythms (Everything else has failed) - CORRECT ANSWER=> *Fires normally
-Idioventricular 20- -Accelerated idioventricular 50-100"
“Normal sinus rhythm - CORRECT ANSWER=> Regular
Rate: 60- P Wave: Present, upright PR Interval: 0.12-0.20 sec QRS: <0.12 sec"
