Where are the most common locations for measing a Lead II ECG - ANSWER ✔---R wrist R ankle L
ankle
P wave - ANSWER ✔---atrial depolarization, systole
QRS Complex - ANSWER ✔---ventricular depolarization, systole

Plethysmometer - ANSWER ✔---instrument to measure oxygen saturation
, What is the heartbeat if 1 cycle lasts 0.55 secs? - ANSWER ✔---60/0.55= 109
The ______ trANSWERducer is used to determine pulse amplitudes and rates - ANSWER ✔---pulse
What is the purpose of the null hypothesis? - ANSWER ✔---no statistical significance exists in a set
of given observations
