Shortness of Breath
Alternate Names : Dyspnea, Trouble Breathing, Difficulty Breathing, SOB
How is the condition diagnosed?
Diagnosis of the cause of shortness of breath begins with a history and physical exam. This may be all that is needed. But usually more tests have to be done, and they are based on the suspected condition. Blood tests and chest x-rays are commonly performed. Other tests may include an ECG, or electrocardiogram, which measures the electrical activity in the heart. An ECG can often help diagnose heart conditions that may be causing shortness of breath. Other tests may be needed in some cases, such as special x-rays or breathing tests.
