SUMMARY

This discussion focuses on obtaining information and circuit diagrams for ECG machines, specifically for creating a simple wireless ECG using Bluetooth or RF technology. The user references HowStuffWorks for general information but finds it lacking in technical details. They recommend a specific academic paper titled "A Portable, Low-Power, Wireless Two-Lead EKG System" from Harvard University as a valuable resource for understanding the electrode circuit in ECG machines. Additionally, they mention a website that interprets EKG traces but does not provide insights into the machine's operational mechanics.

PREREQUISITES
  • Understanding of ECG machine components and functionality
  • Familiarity with Bluetooth and RF communication technologies
  • Basic knowledge of electronic circuit design
  • Ability to interpret academic research papers in biomedical engineering
NEXT STEPS
  • Research "Bluetooth Low Energy (BLE) for medical devices"
  • Study "ECG signal processing techniques"
  • Explore "Wireless ECG monitoring systems" in biomedical literature
  • Review "Electrode placement and configuration for ECG" guidelines
USEFUL FOR

Biomedical engineers, electronics hobbyists, and developers interested in creating wireless ECG monitoring solutions will benefit from this discussion.

I'm looking for info/help/cct diagrams on ECG machines, how they work etc etc. the full works. Looking to make a "simple" wireless ecg on bluetooth/rf.
any help? sites? thanks:)
 
Engineering news on Phys.org
I went to Howstuffworks.com and did a search. They don't have a direct explanation about how EKG machines work, but they did have a link to this interesting site:

http://themdsite.com/default.cfm

That site is more about interpreting the EKG trace, not about how the machine measures it.

Then I googled ekg machine electrode circuit and got lots of good hits. Here's the first one:

"A Portable, Low-Power, Wireless Two-Lead EKG System"

Hope that helps. -Mike-
