My dh was diagnosed with Atrial Fibrillation about nine months ago. He has been hospitalised (overnight) on 3 or 4 occasions in the past nine months due to this. Would this be considered a disability? He is a hard worker but I am concerned that his work and stress levels are compounding the AF. My SIL feels that this is a disability and we could get some help (which is much needed due to Dh being the only driver in the house/ only worker/ breadwinner).
