- 2Electrocardiogram (ECG)a graph showing the change in potential difference produced by the heart, used to monitor heart action.

- 4Pulse oximetera device that uses LEDs and light detectors to measure the amount of oxygen in the blood.
- 5Pacemakera device that is used to help the heat beat properly by detecting the action potentials and applying electrical signals to regulate the heart action.
