ECG and Pacing Review Study Guide
1. 110–250
• Answer: vtach rate
• Rationale: Ventricular Tachycardia (V-tach) is characterized by a rapid heart rate
originating from the ventricles, typically ranging between 110 and 250 beats per minute
with wide QRS complexes.
2. 0.36–0.44
• Answer: normal QT interval
• Rationale: A normal QT interval represents the time from the start of the Q wave to the
end of the T wave. It typically lasts between 0.36 and 0.44 seconds (360–440
milliseconds) when corrected for heart rate.
3. 500
• Answer: QT high limit
• Rationale: A QT interval corrected (QTc) greater than 500 milliseconds is a critical
threshold. It significantly increases the risk of developing life-threatening ventricular
arrhythmias, specifically Torsades de Pointes.
4. QT interval
• Answer: represents the total duration of ventricular depolarization and
repolarization (Note: Fixed a typo in the original prompt from "depolarization of
phases")
• Rationale: The QT interval encompasses the entire electrical cycle of the ventricles,
including both the electrical activation (depolarization) and the subsequent recovery
phase (repolarization).
5. HR
• Answer: the higher the HR, the shorter the QT interval
• Rationale: The QT interval varies inversely with heart rate. As the heart beats faster, the
cardiac cycle compresses, shortening the time required for ventricular repolarization.
