[Energy balance of the myocardium and its correction using antiarrhythmics].

Changes in energetic balance (chi) during the transition of myocardium from norm to hypoxia and under antiarrhythmics effect were analysed on a mathematical model of the heart ventricle band. (chi-useful work/consumed energy ratio. Orciprenalin was shown to increase chi in the state close to the norm; quinidine, bretilium, procainamide, propranalol increase chi only under hypoxia; varapamile, as well as lidocain when it improves conduction ought to be effective for each initial (before therapy) state of the myocardium.
