Prepare for your EKG/ECG Technician certification exam with these practice questions and answers. This guide covers cardiac anatomy, rhythm interpretation, lead placement, arrhythmia recognition, and troubleshooting.
Q: normal sinus rhythm
Answer: R-Rs varymore than 3 small box of variation
Q: sinus bradycardia
Answer: pause not equal to R-R
Q: sinus tachycardia
Answer: pause equal to R-R
Q: sinus rhythm with sinus arrhythmia
Answer: 60-100premature beat occurs before the next normally expected beat
Q: sinus rhythm with sinus arrest
Answer: 60-100at least 3 different P waves
Q: sinus rhythm with sinoatrial block
Answer: 101-150at least 3 different P waves
Q: premature atrial complexes (PACs)
Answer: 150-250unable to see P wavesP wave hidden in T wavesQRS<0.12
Q: wandering atrial pacemaker
Answer: 350-400fibrillatory wavesP waves replaced with wavy baseline
Q: multifocal atrial tachycardia
Answer: 250-350P waves replaced with sawtoothed futter wavers
Q: supraventricular tachycardia
Answer: PR <0.1240-60no P wave
Q: atrial fibrillation
Answer: PR <0.1261-100
Q: atrial flutter
Answer: PR <0.12101-180
Q: junctional escape rhythm
Answer: PAC with short QRS
Q: accelrated junctional rhythm
Answer: PR >0.20
Q: junctional tachycardia
Answer: PR interval progressively gets longer until QRS drops
Q: premature junctional contraction
Answer: PR interval is constantdrops QRS randomlynot 1:1, more PS than QRS
Q: 1st degree sinus rhythm
Answer: PR interval is random
Q: 2nd degree type 1
Answer: QRS >0.12
Q: 2nd degree type II
Answer: NSR w ventricular escape beat following a pause converting back to NSR
Q: 3rd degree heart block
Answer: QRS >0.12
Q: premature ventricular complexes (PVCs)
Answer: 20-40not 1:1, no P wavesQRS wide and bizarre
Q: venticular escape beat
Answer: not 1:1 no P wavesQRS wide and bizarre
Q: interventricular conduction delay
Answer: absent rhythmnot 1:1, no Ps or QRSs
