Hi I am new here and would like some advice. My husband had atrial fibrillation and an echogram showed thickening of the left ventricle. He has an appointment with a Cardiologist but not until the end of September. He is on bisoprolol, lisinopril and fuseomide. He has been getting breathless but more recently it has got worse to the point where any physical excretion leaves him gasping for breathe. Most of the time he is very sleepy and out of sorts. He went back to the GP on Monday, who said to double the fuseomide but this lowered his BP even more and is making him dizzy. He has an appointment next Tuesday with his GP. Any advice on what he should be asking. I am feeling quite helpless.
