Don't forget to keep your hands and fingers from contacting your leg or other body parts as it'll read thru that shortcut.
So basically this is an ad generating machine right? Sounds like they've got it all figured out. I went with the Nuvomed device as it requires no subs.
When you're doing the single lead. Should have the phone above the device, sidways where the top of your phone is above left hand and bottom of phone is on the right hand
How does emf and wifi affect a body and an EKG?
I did test mine while grounded on this earthing sheet I’ve been testing and it seemed to really smooth out and normalize contractions but I’ve yet to test near Wi-Fi and stronger emfs.
How can this be a 6 lead test with 2 thumbs? Looks like a Scientology E-Meter scam!
Yeah, that is pure BS right there on that thing.
A 6-lead or 12-lead literally has leads (wires) connected to very specific areas of the body in order to pick up signals that the HEART PRODUCES in those areas.
Those DIFFERENT signals are not sent to the fingers or at least, the signal sensed would be, at best, a mix of signals that the heart produces.
I've seen some review of these by doctors who say that they love them.
I am VERY SUSPICIOUS of those "Doctors" when I see them rave at the waveform produced by these finger type devices.
If you compare the waveforms to a real ECG machine, you can instantly see how the waveform on these finger things is very crude and not accurate at all.
The real ECG machines product a very sharp waveform that is very accurate.

Waste of money. I can determine those rhythms by checking a pulse.
By checking pulse, you can calculate heart rate and feel if there's any arrhythmia.
However, you CAN NOT detect what's causing the arrhythmia, i.e. PVC, PAC, A-Fib, etc.
Only electrical triggers and some good mathematical algorithms can present that.
And let me tell you, the math is intensive!
The algorithm(s) will have coding for at least 2 filters:
- Chebyshev
- Butterworth
Inside an ECG device, the signals can be messy if directly sent to a display.
The filters are used to filter out "noise" and focus on certain frequency ranges.
There's also filtering to remove "ripple" that may present in the signal, using low pass filtering. i.e. 60 cycle hum (that low frequency buzzing sound).
Then, to detect PVC, for example, the code has to detect the specific lower frequency this cases, analyze the timing of the bits of the waveform to show PVC or PAC or A-Fib, etc.
With Tachycardia and Bradycardia, there's algorithms for that too. This math has to analyze if the beats are in fact T or B, by analyzing their length and repetition (among other things).
There's a lot more in the coding, but I just go down this road to clarify that even if someone THINKS that they can detect heart conditions just by taking a pulse, they are wrong!
Sorry..... not sorry.
You may ask, how do I know this stuff? That's because I've designed my own ECG device and I'm often tweaking the code and algorithms to produce the most accurate, NOISE-FREE waveforms that I can.
In a future revision of my device, I want to add SpO2 monitoring. I'm contemplating also adding BP functionality!
@BlondieSL 100 = Tachycardia, Regularly irregular = pvc/pjc/pac (usually), Irregularly irregular = afib (usually)
I can even determine your heart rate within about 4bpm without counting or timing it.
I've been a paramedic for about 30 years.
Not sorry, not sorry.
As for the rest of your post...good luck. If you're just thinking of adding SpO2 and NIBP, I must ask...who are you making this monitor for? Hospital and prehospital settings have no use for a stand-alone monitor.
Did you think about adding SpCO, ETCO2, defib, pacing, 12 lead or 15 lead capability?
