Question
Which of the following corresponds to ventricular depolarisation?
Question 18
Answer
- a. P Wave
- b. QRS complex
- c. ST Segment
- d. T Wave
Solution
The ventricular depolarization corresponds to the QRS complex.
Here's a step-by-step explanation:
-
The P wave represents the depolarization of the atria (the two upper chambers of the heart). This is when the atria contract to pump blood into the ventricles.
-
The QRS complex represents the depolarization of the ventricles (the two lower chambers of the heart). This is when the ventricles contract to pump blood out of the heart. This is the strongest contraction and is often what is felt as the heartbeat.
-
The ST segment represents the period when the ventricles are depolarized.
-
The T wave represents the repolarization of the ventricles. This is when the ventricles relax and reset for the next heartbeat.
So, the answer to your question is b. QRS complex.
