Across
- 3. when the heart can not be stimulated to depolarize
- 6. propagate the electrical impulse
- 8. ventricular repolarization
- 10. 60-100bpm normal pacemaker
- 11. outermost protective sac of the heart
- 13. determined by preload, contractility, and afterload
- 14. 2nd and contraction phase ventricular emptying
Down
- 1. tropy, strength of cardiac muscle contraction
- 2. tropy, rate of nervous impulse contraction
- 4. 1st and relaxation phase allows for ventricular filling
- 5. positive deflection representing atrial depolarization
- 7. complex, represents ventricular depolarization
- 9. 40-60bpm
- 10. the more the myocardial muscle is stretched the greater the contraction
- 12. tropy, increases or decreases heart rate.
- 14. heart sound of the atrioventricular valves closing
