ECG INTERPRETATION PRACTICE: HEART
RHYTHMS AND SEGMENT ANALYSIS 2026
LATEST GUIDE GRADED A+

What are the seven standard components evaluated in an
ECG practice strip?




Regularity, Rate, P Wave, PRI, QRS, QT, and ST segment.
What does the 'Regularity' component of an ECG strip
assess?
Whether the rhythm is regular or irregular.
What is the clinical interpretation of an ECG with regular
rhythm, 75 bpm, upright P waves, PRI of .20, QRS >.12, and
QT of .36?
AV paced with electrical capture.
What is the clinical interpretation of an ECG with regular
rhythm, 40 bpm, upright P waves, PRI of .16, QRS of .12, and
QT of .44?
Sinus Bradycardia.
What is the clinical interpretation of an ECG with irregular
rhythm, 140 bpm, no P waves, QRS of .06, and no PRI/QT?

, Atrial Fibrillation with uncontrolled rate.
What are the characteristic ECG findings for Atrial
Fibrillation?




Irregular rhythm, absent P waves, and no measurable PRI.
What does a QRS duration of >.12 seconds typically
indicate?




A wide QRS complex, often associated with bundle branch blocks
or ventricular rhythms.
How is Sinus Bradycardia defined by rate?
A heart rate below 60 beats per minute.
What does a 'chaotic' regularity and 0 rate on an ECG strip
represent?
Ventricular Fibrillation or asystole.
What is the normal range for a PR interval (PRI)?
