EXAM STUDY GUIDE AND TEST BANK 2025-2026
Q1: Which lead is considered the standard for monitoring heart rhythm?
A: Lead II – provides clear view of P waves and QRS complexes. ■
Q2: What is the normal duration of a P wave on an ECG?
A: 0.08–0.12 seconds – indicates normal atrial depolarization. ■
Q3: Which interval represents atrioventricular conduction time?
A: PR interval – measures conduction from atria to ventricles. ■
Q4: What is the normal duration of the PR interval?
A: 0.12–0.20 seconds – indicates normal AV node conduction. ■
Q5: Which wave represents ventricular depolarization?
A: QRS complex – indicates ventricular contraction. ■

Q6: What is the normal duration of the QRS complex?
A: 0.06–0.10 seconds – reflects normal ventricular conduction. ■
Q7: Which interval represents total ventricular depolarization and repolarization?
A: QT interval – important for assessing risk of arrhythmias. ■
Q8: What factors can prolong the QT interval?
A: Electrolyte disturbances, medications, and congenital conditions – increases arrhythmia risk. ■
Q9: Which ECG finding indicates atrial fibrillation?
A: Irregularly irregular rhythm with absent P waves – hallmark of AFib. ■
Q10: Which ECG finding indicates atrial flutter?
A: Sawtooth flutter waves, usually at 250–350 bpm – indicates atrial reentrant circuit. ■
