Across
- 3. this has a depolarization of 15-40bpm
- 5. the trigger for myocardial contraction
- 7. electrical gradient just before excitation
- 8. the membrane returns to the normal resting potential
Down
- 1. depolarizes before the LA
- 2. a rapid change in membrane potential
- 4. this has a intrinsic depolarization rate of 60-100bpm
- 6. the direction and magnitude of an electrical current within the heart
