Could breathlessness be related to the heart?
Breathlessness can have several explanations. Its timing, triggers and associated symptoms help guide a careful assessment.
There is more than one possible cause
Breathlessness may be related to the heart, lungs, fitness, anaemia, anxiety or other factors. A clinical assessment considers the symptom alongside your history rather than assuming a single explanation.
Questions a cardiologist may ask
It is useful to know whether breathlessness occurs during exercise, at rest or when lying down; whether it developed suddenly or gradually; and whether there is chest discomfort, swelling, palpitations or fainting.
Deciding whether tests are needed
The next step depends on the individual. Examination and basic observations may be followed by tests such as an ECG or echocardiogram when clinically appropriate.
