Quizplus · Accepted Answer

Evidence of electrical capture, while important, is less helpful in determining the effectiveness of transcutaneous pacing compared to the other options because it does not directly indicate that the heart's mechanical activity has improved. Mechanical capture, increased level of consciousness, and increased blood pressure are direct indicators of improved cardiac output and perfusion.
