Question 2

Which step of impulse conduction is most conducive to atrial kick?

Accepted Answer

A)  The firing of the sinoatrial node, which results in atrial depolarization

Question 5

Why do many patients with very high heart rates frequently have chest pain and shortness of breath?

Accepted Answer

A)  Patients with heart disease frequently have an anxiety disorder as well. 
B)  The rapid pounding of the heart in the chest wall causes the physical pain. 
C)  The heart muscle gets tired from the increased work. 
D)  The decreased diastolic time decreases oxygen delivery to the myocardium.
