Caught quite a number of premature junctional complexes but no PVCs (I have a lot of both now as I am uploading this video). I thought it should be fun to have all three - visual throbbing, ECG and sound in one video. As a result, neither is of decent quality. But anyway, enjoy!
Not really a cardiophile myself but I think the sound made by a heart is so special, more than words can express. It’s like a signature, signed only for that special someone. Soothing, calming, way better than sedative.
Could not agree more, whenever I’m having a hard time sleeping I pull out my headphones or my steth and I’m out like a light
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.
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.
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).
