What is hypernatremia?
- Too much sodium in the bloodstream
- Inhibits calcium entry into the cell
- Depresses overall heart activity and becomes flaccid (negative inotropy)
What is hypercalcemia?
- Too much calcium in the bloodstream
- Negative chronotropic and increased ionotropy (-, +)
- Increased heart irritability
- More calcium into the cytoplasm
What is hyperkalemia?
- Too much potassium in the bloodstream
- Peaked T waves
- Tented T waves
What is hyponatremia?
- Depolarization delay
- Decreased heart rate
What is hypocalcemia?
- Increased chronotropy and decreased ionotropy (+, - )
- Less heart contractility
What is hypokalemia?
- Lowers RMP (makes it more negative)
- Decreases heart rate
- U waves
