    A positive dromotropic effect would

    • Increase conduction velocity through AV node

    • Decrease conduction velocity through AV node

    • Increase heart rate

    • Decrease heart rate

    Correct Answer
    A. Increase conduction velocity through AV node
    Explanation
    Dromotropic effects are on conduction velocity, not heart rate.

    Rate this question:

  • 6. 

    The first heart sound (Lub) corresponds to

    • Opening of the AV valves

    • Closure of the Semilunar valves

    • Closure of the AV valves

    • Opening of the Semilunar valves

    Correct Answer
    A. Closure of the AV valves
    Explanation
    No sound is made with the opening of the AV valves, only the closing of them.

    Rate this question:

  • 7. 

    Which of the following would increase stroke volume? (Select 3)

    • Increased preload

    • Increased contractility of the heart

    • Increased afterload

    • Decreased afterload

    • Decreased preload

    Correct Answer(s)
    A. Increased preload
    A. Increased contractility of the heart
    A. Decreased afterload
    Explanation
    A higher afterload creates more pressure against the contraction of the heart resulting in a decreased stroke volume. Increased preload increases stroke volume because of the Frank-Starling Law of the heart (more muscle is stretched, the greater the force of contraction)

    Rate this question:

  • 8. 

    During isovolumetric contraction and isovolumetric relaxation

    • All valves are closed

    • All valves are open

    • AV valves are closed but semilunar are open

    • AV valves are open but semilunar are closed

    Correct Answer
    A. All valves are closed
    Explanation
    Isovolumetric - No change in volume, all valves must be closed.

    Rate this question:

  • 9. 

    The plateau of a cardiac action potential is due to 

    • Inward flow of calcium

    • Outward flow of calcium

    • Inward flow of potassium

    • Outward flow of potassium

    Correct Answer
    A. Inward flow of calcium
  • 10. 

    Atrial depolarization begins at the

    • SA node

    • AV node

    • Bundle of HIS

    • Purkinje Fibers

    Correct Answer
    A. SA node
  • 11. 

    The SA node's auto rhythmic rate of firing would give us a heart rate of 100 bpm. The reason the average resting heart rate is lower than this (around 72 bpm) is due to 

    • A positive dromotropic effect

    • A positive chronotropic effect

    • Increased Parasympathetic input

    • Increased Sympathetic input

    Correct Answer
    A. Increased Parasympathetic input
    Explanation
    Sympathetic input and Positive chronotropic effect increase heart rate. Positive dromotropic effect increases conduction velocity. Only parasympathetic input would reduce the heart rate.

    Rate this question:

  • 12. 

    A patients end diastolic volume (EDV) is 120 ml and their end systolic volume is 50 ml, what is the patients stroke volume (SV) and cardiac output (CO) if they have a heart rate of 65 bpm

    • SV = 70 ml, CO = 4.55 L/min

    • SV = 70ml, CO = 45.5 L/min

    • SV = 60 ml, CO = 6.5 L/min

    • SV = 50ml, CO = 3.25 L/min

    Correct Answer
    A. SV = 70 ml, CO = 4.55 L/min
    Explanation
    SV = EDV - ESV = 120 - 50 = 70ml.
    CO = SV x BPM (in liters) = 0.07 L x 65 BPM = 4.55 L/min........****SV is in ml, CO is in L/min

  • 13. 

    Out of the 6 precordial chest lead positions, only one of them is on the right side of the heart.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Slide 20

    Rate this question:

  • 14. 

    A lower ventricular end diastolic volume will create a greater stroke volume (all other things held constant)

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A higher ventricular end diastolic volume will create a greater stroke volume because of the increased stretching of the heart.

    Rate this question:

  • 15. 

    A cardiac ECG wave segment is the same as an interval

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Specifics are unknown....just know they are not the same thing.

    Rate this question:

  • 16. 

    Conduction velocity in the heart

    • Is fastest in AV node

    • Is faster in the Bundle of His than in the Purkinje Fibers

    • Is faster in the AV node than in the Bundle of His

    • Is faster in the Purkinje fiber system than in the AV node

    Correct Answer
    A. Is faster in the Purkinje fiber system than in the AV node
    Explanation
    Conduction velocity slows at the AV node (0.5 m/sec), then speeds up in the Bundle of His (2 m/sec), then speeds up again in the Purkinje fibers to (4 m/sec)

    Rate this question:

  • 17. 

    Ventricular depolarization spreads from ________ to _________ and would be located at the _____ segment of an ECG/EKG

    • Epicardial surface, endocardial surface, QRS complex

    • Endocardial surface, epicardial surface, QRS complex

    • Endocardial surface, epicardial surface, PR interval

    • Epicardial surface, endocardial surface, PR interval

    Correct Answer
    A. Endocardial surface, epicardial surface, QRS complex
    Explanation
    The heart depolarization occurs from inside to out-- from the endocardial surface (inside of the heart), through the wall, then to the epicardial surface (outer surface of the heart). REpolarization occurs in the opposite direction (epicardial --> endocardial)

    Rate this question:

  • 18. 

    A heart attack would best be detected at the _____ portion on an ECG

    • QRS complex

    • PR interval

    • ST segment

    • P segment

    Correct Answer
    A. ST segment
    Explanation
    Elevation of the ST segment is often indicative of heart injury or ischemia (inadequate blood supply to the heart). In a heart attack, the ST segment will lower over time closer to physiological norms.

  • 19. 

    A heart murmur heard in systole could be (Select 2)

    • Aortic Stenosis

    • Mitral Regurgitation

    • Mitral Stenosis

    • Aortic Regurgitation

    Correct Answer(s)
    A. Aortic Stenosis
    A. Mitral Regurgitation
  • 20. 

    An increase in NE will result in 

    • Larger ejection fraction

    • Smaller ejection fraction

    • Larger EDV (end diastolic volume)

    • Decreased myocardial contraction

    Correct Answer
    A. Larger ejection fraction
    Explanation
    NE is a positive Inotropic factor (and is sympathetic) so it will increase heart contractility, decrease EDV (because of increased heart rate reducing the diastolic filling time), and increase stroke volume.

    Rate this question:

  • 21. 

    If a doctor places his stethoscope at the level of the 2nd intercostal space (on both the right and left side of the sternum), what sound is he trying to hear most clearly?

    • Closure of the semilunar valves

    • Closure of the AV valves

    • Closure of the bicuspid valve

    • Opening of the semilunar valves

    Correct Answer
    A. Closure of the semilunar valves
    Explanation
    This location is ideal for hearing the closure of the semilunar valves. The closing of the semilunar valves would also be the second heart sound (dub).
