    Do you have any better power supply that is suitable for a radio system?

    It depends on what sort of radio you're talking about.

    I do not answer private messages asking for help because no one else can: benefit from advice I may give or correct me if I'm wrong.

    Please ask on the open forum if you have a question and I'll be happy to help,
    if I know the answer.

    I do not know medical isolation requirements but I bet the insulation must be double-insulated.

    Find out the law in your country about isolation for medical electronic equipment and design a circuit that conforms to the law.
    I have never made an isolated ECG circuit.
