When I go to sleep at night, I suddenly can’t breathe and wake up. This is a situation that requires specific analysis of the problem. First, for young people, there is no organic disease, that is, usually relatively healthy, no bronchitis, bronchial dilation, and myocarditis and other organic diseases. If this situation occurs, the first thing to consider is the possibility of anxiety disorders. This disease usually electrocardiogram, cardiac ultrasound, and chest examination results are normal, you can take some oral nerve-regulating drugs for treatment. Secondly, for the elderly, if you suddenly can’t breathe and hold your breath, you need to consider the possibility of cardiac insufficiency, and you need to go to the cardiovascular medicine department of a regular hospital for a checkup, so that the doctor can determine whether the cardiac function is normal. Do an electrocardiogram, cardiac ultrasound, as well as laboratory tests for cardiac enzymes, brain natriuretic peptide and other such items.
