Therefore, when Cordarone therapy is initiated, a baseline chest X-ray and pulmonary-function tests, including diffusion capacity, should be performed.
Because of its life-threatening side effects and the substantial management difficulties associated with its use see below Cordarone is indicated only for the treatment of the following documented, life-threatening recurrent ventricular arrhythmias when these have not responded to documented adequate doses of other available antiarrhythmics or when alternative agents could not be tolerated.

Even in patients at high risk of arrhythmic death, in whom the toxicity of Cordarone is an acceptable risk, Cordarone poses major management problems that could be life-threatening in a population at risk of sudden death, so that every effort should be made to utilize alternative agents first.
