Info/help/cct diagrams on ECG machines

[juming]

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:)

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-

Sure, I would be happy to provide some information on ECG machines and their diagrams. ECG machines, also known as electrocardiogram machines, are medical devices used to record the electrical activity of the heart. They are commonly used by healthcare professionals to diagnose and monitor heart conditions.

The basic components of an ECG machine include electrodes, which are attached to the patient's chest, arms, and legs, a cable that connects the electrodes to the machine, and the machine itself. The machine works by detecting the electrical signals produced by the heart and then amplifying and recording them on a graph paper or digital display.

As for circuit diagrams, there are various types of ECG machines with different circuit designs. However, the basic circuit consists of a series of amplifiers, filters, and a display unit. The electrodes act as input, and the electrical signals from the heart are amplified and filtered before being displayed on the graph paper or digital display.

If you are looking to make a wireless ECG machine using Bluetooth or RF technology, there are several resources available online that can guide you through the process. Some helpful sites include Instructables, Arduino Project Hub, and Hackster.io, where you can find step-by-step instructions, diagrams, and code for building your own wireless ECG machine.

I hope this information helps. Best of luck with your project!
