Hey, I'm Daniel and new in the forum! I'm trying to build a circuit to preform ECG with DRL for a school project. I'm having problems with amplification and simulation. In the circuit I'm using the Wilson Central (Right Arm + Left Arm + Left Leg), one high pass filter (0.5 Hz), one low pass...

Hello AAC, I want to design a low pass filter with a cutoff frequency of 100Hz that would take a 150Hz input. The first photo is my simulation schematic, and the second has the bode plots from the AC sweep analysis. I didn't expect the roll-off to look like that, so I thought I might be doing...

Hello everyone, I'd like to request some help with an ECG Holter Receiver Board. This is my first time designing a MCU board. I am basing this design on this article from Analog Devices: https://www.analog.com/en/resources/analog-dialogue/articles/ecg-front-end-design-simplified.html As some...

I am trying to create a 2 stage Mutiple feedback bandpass filter for a band of Frequenz of 8 to 18hz for ECG Rpeak detection. The 1st stage has cut off frequency band of 4.5 to 13hz and 2nd stage have a band of 10 to 26hz. I am using OPA2338 and working voltage of +v=3.3v and -v=0v. Circuit is...

ECG leads generally see voltages in the range of -5mV to 5mV and a frequency range of .05Hz - 150Hz. We are peripherally stimulating the patients with up to 200v at a frequency of 1kHz elsewhere on the body for about 100mSec and it disrupts our front-end ECG chip. I need to protect the ECG leads...

Hi, I was working on a thesis project on a portable ECG device, I checked these CIRCUIT: https://raw.githubusercontent.com/gaodingpan/ECG-on-Teensy/master/CSE_EE%20474%20Lab%206_%20Analog%20Front%20End%20for%20an%20Electrocardiograph.jpg VIDEO...

Hello. Thank you for clicking on my article. I'm from Korea and a college student. I'd like to find a solution. My circuit simulation speed is too slow. So I want to speed up. I saw what other people did at Google and made it. I want to speed up the simulation. I'd appreciate your help.

Hi guys I am on a little project (ecg with an arduino) I followed all the topics , the diagrams to wiring , electrodes placement.... But never I can get an classic ECG GRAPHIC Please help Best regards AD8232 Gnd-gnd 3,3v -3,3 v Output -a0 Lo- dig 11 Lo+- dig 10 Sdn- none Code: Void setup() {...
