a. What information does the ECG provide about heart function?
b. Describe the function of the areas of the heart usually supplied by the left coronary artery.
c. Describe the effect if the atria were to contract at the same time as the ventricles, or if the ventricles contracted slightly before the atria.
d. Predict three basic ways that cardiac function could be impaired.
d. Discuss the importance of collateral circulation and explain how collateral circulation can be maximized.
e. Why is there a pause after the atrial contraction and before the ventricular contraction?
f. Predict the outcome if more blood is pumped into the pulmonary circulation than into the systemic circulation during each cardiac cycle.
