Which one of the components of ECG in human is correctly interpreted below?
View answer and explanation
Correct option: C
Peak P and Peak R together – Systolic and diastolic blood pressure
Option D (Peak P – Initiation of left atrial contraction only) is incorrect. Peak P represents the initiation of contraction of both atria, not just the left atria. Option A (Complex QRS – One complete Pulse) is incorrect because QRS represents ventricular depolarization, not a complete pulse. Option B (Peak T – Initiation of total cardiac contraction) is incorrect because T represents ventricular repolarization. Option C (Peak P and Peak R together – Systolic and diastolic blood pressure) is correct because the ECG indirectly reflects blood pressure changes during systole and diastole.
