Breathlessness
Shortness of breath can be an incapacitating symptom that requires diagnostic tests, including blood tests, chest X-ray, ECG, and echocardiogram (ultrasound scan of the heart), to determine the cause. The problem can be due to deconditioning, natural ageing or unhealthy weight, but it can also be caused by cardiac conditions, such as heart failure, coronary artery disease or arrhythmias.
