Heart arrythmia is very big on the initial Chinese medical. They usually give you several EEGs to see if you get one which is normal. If the arrythmia continues you most likely won't pass. After the initial ie just a recurrent and something non-normal is detected on the EEG they will do a color ultrasound and a 24 hour Holter monitor to see the extent of your arrythmia. If they determine you have any other abnormalities you probably won't pass a recurrent. If it is something slight they might pass you with a waiver and an hours restriction usually 60 hours per month. You will do these tests every 6 months if you are on a waiver until eventually they fail you. If you have more than 15 prestarts in a 24 hour period you will fail. Many people have over 1000 prestarts and simply getting up off the couch to walk into the kitchen can cause a prestart so you need to limit your mobility during a Holter monitor test ie become a recluse on the couch.
