Question

Fill out the heart rate table in the sitting tab

Lab Notebook Standing Sitting After Exercise Cycle 2 ECG Component Cycle 1 Cycle 3 Mean Normal Duration Os 0.06-0.11 P wave P-R interval P-R segment Os 0.12-0.20 Os 0.08 Os <0.12 Os 0.36-0.44 QRS complex Q-T interval ST segment Os 0.12 Os 0.16 T wave Amplitude Omv <0.25 Stand P wave

Answer 1

Here are the normal physiological ecg values:

For the sitting column, fill the rows with close to normal or normal values

For standing, the QRS will be minimally shortened, R wave height will increase, Q wave height increases a little, segments remain more or less normal

NHeart rate			60 - 100 bpm
PR interval			0.12 - 0.20 s
QRS interval			≤ 0.12 s
QT interval			< half RR interval (males < 0.40 s; females < 0.44 s)
P wave amplitude (in lead II)			≤ 3 mV (mm)
P wave terminal negative deflection (in lead V1)			≤ 1 mV (mm)
Q wave			< 0.04 s (1 mm) and < 1/3 of R wave amplitude in the same lead
