2. Description of the Related Art Many antiarrhythmic agents for stopping and preventing arrhythmias have already been marketed. However, the falcainide and encainide CAST (Cardiac Arrhythmia Suppression Tria) were performed to demonstrate that suppression of ventricular arrhythmias could lead to lower patient mortality.
l), SWORD (Survival With O) by d-sotalol
Large-scale clinical trials such as rald-Sotalol Trial) resulted in worse prognosis compared to the placebo group. As a cause of such worsening of the prognosis of life, antiarrhythmic drugs suppress cardiac function and the occurrence of new arrhythmias due to the action of drugs, so-called proarrhythmic actions are considered. In addition, the effective rate of existing antiarrhythmic drugs was not satisfactory due to dose limitation due to side effects, and was not satisfactory. (Medicine
And Drug Journal, Vol. 30, No. 9, 24-81 (1994)) Therefore, the development of a new antiarrhythmic agent having both safety and efficacy has been awaited.

Pharmacological Test Example 2 Measurement of Action Potential Change of Canine Purkinje Fiber (Test Method) A Purkinje fiber specimen cut out from the free wall of the right ventricle of a dog was perfused with a normal Tyrode solution, and the fundamental cycle was 1 Hz.
It was driven and used by electrical stimulation. Using a standard glass microelectrode to record the action potential, measure the maximum rise rate (Vmax) of the action potential and the action potential duration (APD50, APD75, APD90) until 50%, 75%, and 90% repolarization. The same measurement was performed on the Tyrode solution to which the test compound was added under perfusion. (Results) The change rate of the action potential parameter of the Purkinje fibers at a concentration of 10 μM of the test compounds of Examples 1 to 52 (each used as a hydrochloride) was 5% or less, and hardly affected. On the other hand, flecainide, a typical antiarrhythmic agent, suppressed Vmax by 30% even at 3 μM, and showed class I

General symptoms were observed and the survival rate was determined 48 hours later. (Test compound) All the anilide derivatives of Production Examples Nos. 1 to 52 were used as hydrochlorides. In addition, representative existing antiarrhythmic agents flecainide and pilsicainide were evaluated as comparative examples. (Results) No deaths occurred with the anilide derivative of the present invention, and no particular change was observed in general symptom observation. on the other hand,
