Quiz zum Vortrag
Which of the following is not likely to be seen on an ECG in LVH?
- Shallow R waves in aVL
- Deep S waves in V1
- QRS widening
- Left-axis deviation
- ST-T changes
Which of the following can be used to diagnose LVH?
- S wave in V1–V2 plus R wave in V5–V6 > 35 mm if age > 30 years
- S wave in V1–V2 plus R wave in V5–V6 if age < 30 years
- R wave in V1–V2 plus S wave in V5–V6 > 35 mm if age > 30 years
- S wave in V1–V2 plus R wave in V5–V6 > 15 mm if age > 30 years
- R wave in V1–V2 plus S wave in V5–V6 > 20 mm if age > 30 years
If LVH is suspected, an inverted T wave in V5 indicates which of the following?
- Marked LVH and a worse prognosis
- Acute MI due to blockage of the left anterior descending artery
- Better prognosis with minimal LVH
- Nothing, because T waves are always inverted in V5
- Marked LVH with better prognosis
Which of the following ECG changes is least likely attributable to RVH?
- QRS widening
- Tall R waves in V1
- Deep S waves in lateral leads
- Right-axis deviation
- Tall peaked P waves (> 2 mm)
An axis of what amount would be considered right-axis deviation?
- Greater than 90°
- Less than –45°
- Less than –60°
- Greater than 45°
- Between –30° and 90°
Which of the following findings would be indicative of both left and right ventricular enlargement?
- High voltages in leads V4, V5, and V6 as well as a prominent R wave in V1
- Tall R waves in V1, deep S waves in 1 and aVL, and right-axis deviation
- If patient > 30 years old, S wave in V1–V2 plus R wave in V5–6 > 35 mm
- QRS widening, left-axis deviation, and ST-T changes
- ST elevations in leads II, III, and aVF
