- A. CT Scan
- B. ECG
- C. EEG
- D. Sphygmomanometer

What is the clinical significance of the 'QRS complex' in an ECG?
- A. It marks the start of atrial contraction
- B. It represents ventricular depolarization and signifies the onset of mechanical contraction
- C. It indicates the relaxation phase of the entire heart
- D. It reflects the electrical activity of the SA node only
Answer: B. It represents ventricular depolarization and signifies the onset of mechanical contraction
The QRS complex corresponds to the rapid depolarization of the ventricles, triggering contraction of the heart's main pumping chambers.
