Key Learning Points
Action Potential
ECG Shape, Biphasic Page 6
- A wave that is termed biphasic(a) has an upward and downward deflection.
- If the depolarization wave is traveling at right angles(b) or perpendicular to the positive and negative electrodes the wave on the monitor will be biphasic.
Wave Amplitude Page 7
- The more cells that are depolarizing simultaneously the greater the amplitude of the displayed wave.
