In addition to asthma attack, wheezing and breath-holding symptoms can also occur in chronic bronchitis, emphysema, chronic obstructive pulmonary disease, pulmonary heart disease, respiratory failure, bronchopulmonary cancer, cardiogenic asthma, etc. Based on the past medical history, other symptoms and signs, pulmonary function, blood routine, blood gas analysis, chest X-ray, CT or fiberoptic bronchoscopy, electrocardiogram or echocardiogram, and other physical and chemical examinations, the doctor will guide you to find out if you have asthma.
