General Medicine
A patient was taken up for measurement of the electromechanical systole, QS2, left ventricular ejection time (LVET) and pre-ejection period. While doing the test, it is noted that the carotid transducer measuring pressure is not functioning. Which of the following cannot be measured?
1. QS2
2. LVET and PEP
3. QS2 and LVET
4. QS2 and PEP

📝 Explanation:

QS2 (electromechanical systole): Interval from the onset of the Q wave on ECG to the second heart sound (aortic valve closure).

Can be measured using ECG + phonocardiogram (no carotid pulse needed).

LVET (Left Ventricular Ejection Time): Duration of blood ejection from LV, measured from the upstroke to the dicrotic notch of the carotid pulse tracing.Requires carotid pulse recording.

PEP (Pre-ejection period): Interval from onset of ventricular depolarization (Q wave) to the beginning of LV ejection (upstroke of carotid pulse). Also requires carotid pulse recording.


If the carotid transducer is not functioning, you cannot measure:

LVET (needs carotid upstroke → dicrotic notch)

PEP (needs carotid upstroke relative to Q wave)

But you can still measure QS2 using ECG + phonocardiogram.
