Question

which deflection wave or segment on an ecg would correlate with the closing of the semilunar valve?

p - q segment
end of t wave
qrs complex
p wave

Explanation:

The end of the T - wave on an ECG represents the end of ventricular repolarization and the closing of the semilunar valves. The P - Q segment is related to the delay at the AV node before ventricular depolarization. The QRS complex represents ventricular depolarization. The P wave represents atrial depolarization.

Answer:

end of T wave
