Hola BeatrizMuchas gracias por tu comentario =D. Durante el desarrollo del proyecto, en un principio pensaba hacer una simulación del circuito con el programa que uso habitualmente (Multisim). Pero recuerda que la señal del corazón es muy particular y no es posible obtener una "fuente de ecg" en el programa. Estuve revisando foros... y por ahí encontré una simulación de un ecg (para Multisim) simbolizado como una fuente de voltaje, la cual puedes procesarla como fuera, ya sea amplificarla, filtrarla o atenuarla. Pero te recuerdo que una señal analógica viene con ruido, así que probablemente los resultados que te de la simulación podrían ser diferentes a los reales en cuanto al procesado de la señ…

Sure! this LV interface is just a common signal visualizer supporting voltages coming out from the Arduino UNO (0- 5V), you can visualize whatever you wish with the LabView file =)

here in Mexico we call it "cable de bocina" (speaker cable), but try to get any cable with metallic shield. =)

Hola, la verdad no sé cómo obtener un pdf... la página me pide ser ususario premium :(

Sadly i don't have any diagram (if your asking for any pdf circuit diagram) .. that's why i uploaded pictures of every stage

Hello!Sorry for the late response. The coding was made entirely in LabView. You can see the block diagram in the last image. Today i uploaded the VI file for anyone so they can take a look.The Arduino board doesn't require any code to run. Just plug it in your computer and follow the LINX wizard, select your board and you're ready to go!

Thank you so much!!
Hi and thank you for your observation. Ceramic capacitors worked good for me when i was making this project. For the notch filter, i couldn't find any 100 nF film capacitors in stores, for this measure, most of them that i found were ceramics.When i was working in the notch filter phase, the circuit (that i found googling around) gave me the most minimal output voltage (compared to other stop-band circuits found) when giving it a 60 hz signal from the function generator. In an Improved version of the circuit, i put another notch filter at the output of the EKG and i replaced the offset stage by a PID stage that heped me to always get the heart signal.
