Can I get an arrhythmia health certificate if I work in a factory?

From the perspective of infectious diseases, any arrhythmia is not contagious, and you can apply for a health certificate.

But not necessarily from a health point of view. If it is sinus arrhythmia, you can get a health certificate. Normal people can have sinus arrhythmia, and it doesn't matter if they take the bus. Some serious arrhythmias are not suitable for work and need rest.
