This semester in Dr. Chu’s Linear Circuit Lab, sophomore Electrical Engineering majors were able to build a simple circuit to measure EKG. Electrocardiography (EKG) is used to measure electrical activity of a heartbeat. EKGs are a widely used tool to diagnose cardiac diseases.
Students assembled the circuit by following a given circuit diagram. The circuit was attached to an oscilloscope, which is a device used to measure electronic waveforms. The students then attached two electrodes on the test patient’s chest. The oscilloscope displayed the EKG reading.
