5. An ECG reading with P waves present at regular intervals, but with the QRS interval absent, indicates the ________ are not depolarizing as they should. ventricles atria AV bundles neurons 6. Which of the following will not increase cardiac output? Increased heart rate Increased stroke volume Increased respiration None of the above 7. Atrial fibrillation indicates the ventricles are not depolarizing properly. True False 8. In an ECG, __________ are combinations of waves and segments. periods complexes patterns intervals

Which one of the following is responsible for generating the first heart sound? a) Opening of the atrioventricular (AV) valves b) Closing of the semilunar valves c) Closing of the atrioventricular (AV) valves d) Opening of the semilunar valves In the electrocardiogram (ECG) of a normal cardiac cycle, the wave called T corresponds to: a) Depolarization of the atria. b) Repolarization of the atria. c) Depolarization of the ventricles. d) Repolarization of the ventricles. e) More than one of the above The cardiac cycle has two phases: Diastole, in which the ventricles relax; and systole, in which the ventricles contract. Systole, in which the ventricles contract; and diastole, in which the ventricles relax. Systole, in which the atria contract; and diastole, in which the ventricles contract. Diastole, in which the atria relax; and systole, in which the ventricles relax. Systole, in which the atria relax; and diastole, in which the atria contract.
