A)RSR configuration in V₁.
B)tall,pointy P waves.
C)symptoms of decreased cardiac output.
D)more P waves than QRS complexes.

Question

Quizplus · Accepted Answer

RBBB usually shows an RSR' pattern in V1, with a wide S wave in V6. This is due to delayed depolarization of the right ventricle, leading to a delayed R wave in V1 and a wider S wave in V6. Tall, pointy P waves may indicate left atrial enlargement, not RBBB. While decreased cardiac output is possible with any block or arrhythmia, it is not a characteristic feature of RBBB. Finally, RBBB should have the same number of P waves as QRS complexes, as the atrial and ventricular rates should match.
