[Anesthesiological problems in cardiopathic patients. Clinical updating].

The activity of a drug is completely defined by experimentation and the results of clinical experiments. Specifically, the use of anaesthetic drugs in cardiopaths must meet certain requirements: no toxicity, no rises in cardiac rhythm. A slight hypotensive action can be tolerated because this is not related to cardiac hypoxia and thus places the myocardium in a more favourable situation.
