Instructables a DIY (Do It Yourself) user generated instruction database, has detailed instructions on how to build a ECG Tester that will output the following:
- Sine Waves
- 1 mVpp4 @ 1 Hz, 5Hz, 10Hz, 50Hz
- Normal Sinus Rhythm Waveform
- Include P wave, QRS complex, T Wave
- 40, 70, 130, 210 bpm5
According to the instructable the device should cost less then $4 each in quantities of 500. Now, I’m pretty sure you don’t need 500 ECG Testers, but the cost shouldn’t be too much more to build just one.
