D)Asystolic tracing.

Question

Quizplus · Accepted Answer

Evidence of mechanical capture refers to the physical contraction of the heart in response to pacing. The presence of a pulse and blood pressure suggests that the heart is successfully contracting and pumping blood, indicating mechanical capture is present. The other options relate to electrical capture (A and B) or lack of capture (D), which are not indicators of mechanical capture.
