ECG HOLTER MONITOR DESIGN

Hello Bill,

I am currently working on a layout design for this ADI solution.

I have a few questions regarding the circuit presented here:

1. From the biomedical point of view, what are the minimum distances between the RL–RA–LA electrodes?
2. From the schematics provided, it is clear how the ADC processing and wireless transfer is accomplished. However, there is no mention for the battery power circuit. Do you have any recommendations regarding power distribution?
3. Do you know of a supplier for ESD Defib protection Devices?
4. For now, I am trying to follow the iRythm or the NUVANT MCT System design for my prototype. If I am going in a totally wrong direction please let me know. I am just starting to learn about ECG monitoring.

Thanks in advance for your help!
