Abstract

An electrocardiogram (ECG) is the recording of the electrical activity from the cardiac tissue during the heartbeat cycle. ECG monitors are used in many healthcare environments such as hospitals and ambulances where monitoring a patient’s vital organs are necessary. The current issue with many ECG monitors in use today is the number of wires that must be connected from the monitor to the patient’s body. A standard 12-lead ECG will have 10 wires connected between the monitor and the patient. When this is combined with any intravenous therapies or other vital monitors (pulse oximeter, blood pressure, etc.) a complicated network of tubes and wires can be created which can limit the ability of the medical professionals. To solve this issue, I have designed the framework for a wireless ECG monitor specifically for surgical applications so that the number of contact points on the patient is minimized. To stand out from other wireless ECG monitors, I will not rely on Bluetooth protocol for data transmission and my device will have the capability for use of up to 10 electrodes if needed. After the electrical potential is sampled by an electrode, a printed circuit board will both amplify and filter the raw signal which will be sent to a Digi XBee® 3 Pro which digitizes the signal and wirelessly transmits the data. A second Digi XBee® 3 Pro receives the data and sends it to an Arduino Nano which displays the incoming signal in real time. This design will eliminate any constraints between the patient and hardware which will ensure a safer experience for the patient and an easier experience for the professional.
