Which lead configuration provides a view of the heart’s electrical activity in the frontal plane?
Answer: Standard limb and augmented leads
The standard limb leads (I, II, and III) and augmented leads (aVR, aVL, aVF) provide views of the heart's electrical activity in the frontal plane.
What does the P wave represent on an ECG?
Answer: Atrial depolarization
The P wave represents atrial depolarization, which is the electrical activation of the atria.
Which part of the ECG tracing corresponds to ventricular depolarization?
Answer: QRS complex
The QRS complex corresponds to the depolarization of the ventricles, which triggers ventricular contraction.
Which lead is typically used for rhythm monitoring in continuous ECG telemetry?
Answer: Lead II
Lead II is commonly used in telemetry because it provides a clear view of the P wave, QRS complex, and T wave.
What is the correct placement for the V3 precordial lead?
Answer: Midway between V2 and V4
The V3 lead is placed midway between V2 and V4 on the chest wall.
Which condition is indicated by a prolonged QT interval on an ECG?
Answer: Torsades de pointes
A prolonged QT interval can indicate an increased risk for torsades de pointes, a type of life-threatening ventricular tachycardia.
