Diy ekg

Has anyone ever built a home made EKG machine? I see there are many plans online, so I was wondering if anyone had any experience with any of them.

They don't seem complicated. It looks like if you can solder, you can build one. If you can't solder you could build one on what they call a bread board.

Any experience?

I've seen little circuit boards on eBay that use the AD8232 chip and already designed and tested IMO, they are far more likely to be safe than something home brew Many cost under $20.. less than the cost of parts.

Some years ago, i bought one to use for EMG… monitoring the muscles around my anus as I retained an enema and then pood. Every time the urge increased and I clenched to resist, the muscle activity increased and as I relaxed to poo, the activity lessened. Interesting, but completely useless information.
