Which EMC (electromagnetic compatibility) devices are helpful for defibrillator design and modification?

The core of defibrillator EMC design is isolation and suppression. High-voltage charging and discharging circuits must be completely enclosed in a metal shield and strictly spatially and electrically isolated from the low-voltage control circuitry. Cables connecting the defibrillator electrode plates should use high-performance shielded cables, with the shield grounded at the device end. The low-voltage ECG monitoring front-end circuitry must be isolated from the high-voltage section using an isolation amplifier, and its input protection circuitry should be able to withstand the residual voltage after defibrillation discharge; high-voltage withstand protection components can be selected. The device's power input port must be equipped with a high-energy surge protector (SPD) or a high-current TVS (e.g., the 15KP series) to handle transients that may be introduced from the power line.
