Which ECG interval measures the combined duration of ventricular depolarization and repolarization?
Answer: QT interval from QRS onset to the end of the T wave
The QT interval spans from the start of the QRS to the end of the T wave, encompassing total ventricular electrical activity.
Why is documenting a patient's current medications on the ECG requisition clinically important?
Answer: Medications such as antiarrhythmics and digoxin can alter rate, intervals, and waveform morphology
Many cardiac and non-cardiac drugs alter heart rate, conduction intervals, and waveform morphology in ways that affect interpretation.
What does a delta wave on an ECG indicate?
Answer: Pre-excitation pattern associated with Wolff-Parkinson-White syndrome
A delta wave is a slurred initial upstroke on the QRS caused by accessory pathway conduction in WPW syndrome.
Which ECG finding requires the technician to immediately notify clinical staff?
Answer: Ventricular fibrillation on the monitor
Ventricular fibrillation is a life-threatening arrhythmia requiring immediate emergency response from clinical staff.
What does the term 'axis deviation' refer to in ECG documentation?
Answer: The mean direction of ventricular depolarization in the frontal plane
Axis deviation reflects an abnormal direction of the heart's electrical activation, often indicating hypertrophy or conduction abnormalities.
How should an ECG technician handle a tracing with persistent artifact that cannot be eliminated?
Answer: Submit the tracing with a written note explaining the artifact and its likely cause
Submitting an artifact-affected tracing with documentation provides the physician context needed for the best possible interpretation.
