Given below is the ECG of a normal human. Which one of its components is human, which one of its components is correctly interpreted below?
complex QRS - One complete pulse
Peak T - Initiation of total cardiac contraction
peak P and peak R together - systolic and diastolic blood pressures
peak P -Initiation of left atrial contraction only
C.
peak P and peak R together - systolic and diastolic blood pressures
Each peak in the ECG is identified with a letter from P to T that corresponds to a specific electrical activity of the heart peak P cause diastolic phase in ventricle while peak R cause systole in the ventricle. Thus, peak P and Peak R together represent diastolic and systolic blood pressures.
