PHIZ 206: ECG and Pulse || 100% Detailed Answers.
Comparing ECG and pulse signals correct answers Both signals are recorded at the skin.
Both signals are recorded using non-invasive techniques.
ECG correct answers periodic electrical signal
Pulse correct answers periodic mechanical signal
Each feature of both signals can be assigned to
__________________________________________________ of the cardiac cycle. correct
answers distinct phases
Why does the heart pump blood? correct answers Blood brings O2 and nutrients to organs while
retrieving CO2 and "waste".
How does the heart do it? correct answers By converting chemical energy (ATP) in to
mechanical energy (pressure).
Blood flow correct answers The flow (F) is equal to the difference in pressure (triangle P)
divided by the resistance (R).
Higher difference in pressure correct answers Higher flow
Lower difference in pressure correct answers Lower flow
Higher resistance correct answers Lower flow
Lower resistance correct answers Higher flow
