Inexpensive EKG with capability to download recorded data, anyone?

I want an image of an ECG strip of my heart with multiple PVCs on it as my banner picture. I wonder what would the the most convoluted way to obtain one?..

Suggestions to get any monitor and photograph the screen are a no. I want better resolution and a longer strip. Can someone recommend an inexpensive monitor with USB and/or BLE interface? (Preferably without a requirement to use propitiatory software in order to get the data.)

It would seem that PC 80A fits the requirements? (Though it is only single channel, with ability to switch input between leads.) Anyone tried to download recordings to the computer? Maybe such person could share a sample of raw data with me, so I could judge how suitable it is for me?

I can suggest you the Contec ECG90A...it works well and it is not so expensive (I paid it 199 $)...you can connect to the PC trough a USB cable  or print the ecg strip directly from the device (you choice from one to three channel  per strip).

I attach ebay link for more detail

Re: Inexpensive EKG with capability to download recorded data, anyone?

Thanks! It's about €350 on average though... And I've already got a shitty one-channel recorder from HealForce. It records the signal as a series of 30 second (4500 sample) uncompressed files in (almost standard) ISO 11073-91064:2009 format. And can transmit in realtime over BLE, though I did not yet check how easy is it to use this functionality.

Just curious how you're supposed to do a 12-lead ECG when there's only 10 leads included. :P

Sucks to have to buy two more when I don't think a two-pack exists.

Re: Inexpensive EKG with capability to download recorded data, anyone?

@patthedrummer if that was a joke then yeah!

If it was not, 12 lead recorder actually uses 8 channels. Three limb leads need 2 channels to record (the third lead is obviously just a sum of the the two); "augmented" leads are, again, produced by averaging pairs. Remaining 6 precordial leads are "real" in a sense that one channel is used per one wire. Remaining right leg wire is not strictly necessary, it is used to get "better averaged" base level.

That said, not all recorders have 8 channels. Some have less, that are connected to different groups of wires at different times.

Yeah, I was joking. But I also clearly don't understand how the wiring of an ECG works. :lol:
