Abstract
Paroxysmal atrial fibrillation and paroxysmal supraventricular tachycardia can be treated using several preparations. Author of this abstract has developed the new method of treatment for paroxysmal supraventricular tachyarrhythmia’s including such disorder of cardiac rhythm in patients with severe heart failure. In accordance with this method combination of preparations with antiarrhythmic action (allapinin + cardiac glycosides) is used.
Paroxysmal AFib are scenes of AFib that happen infrequently and for the most part stop suddenly. Scenes can last a couple of moments, hours or a couple of days before halting and coming back to typical sinus beat, which is the heart's ordinary mood.
A few people may have single scenes of AFib. Be that as it may, the condition may advance to the point that it's consistent, which is alluded to as interminable AFib.
There are three types of AFib:
• paroxysmal
• persistent
• chronic, or permanent
Persistent AFib is characterized by a scene that keeps going longer than 7 days. It doesn't stop without treatment. Typical rhythm might be accomplished with prescriptions or electric shock treatment.
Incessant, or changeless, AFib might be continuous for a long time. Typically, the choice has been made to not reestablish sinus beat, regardless of whether with prescription or with electric shock treatment.
Allapinin is the alkaloid of bromhydrate lappaconitine. This alkaloid was extracted from the perennial plant. It can be extracted from the wild plant of the aconite, which belongs to the group of buttercup plants. It is produced in tablets at 50 mg and in solution for intravenous or intramuscular administration: 1% solution in ampoules at 2 ml. Allapinin occupies the special place among antiarrhythmic agents of the 1st class according to Vaughan-Williams classification. It differs from agents of IA and IB subclass. Being different from quinidine, procainamide, gilurytmal and others agents of the 1st class of antiarrhythmic drugs allapinin in effective antiarrhythmic doses has small influence on the width of ventricular QRS complex, P-Q interval and Q-T interval. Allapinin in doses, which provide denominated antiarrhythmic effect, unlike the other antiarrhythmic drugs, does not lead to reduction of the system arterial pressure and to negative inotropic action in myocardium fibers.
Treatment for AFib includes the accompanying choices:
• resetting the heart's rythm from AFib back to a typical sinus musicality as opposed to controlling the pulse and leaving the individual in atrial fibrillation
• preventing blood clusters
In accordance with the new method of treatment of paroxysmal supraventricular tachyarrhythmias a cardiac glycoside – digoxin (lanoxin) in dose 0,25 mg or strophantin in dose 0,25 mg is administered intravenously. Then in 20-30 minutes after administration of cardiac glycoside allapinin is used intravenously in dose 30-40 mg
In case of suppression of paroxysmal tachyarrhythmia prophylactic treatment must be administered using the above preparations. Allapinin is administered orally in daily dose 75 mg (25 mg 3 times daily). In combination with allapinin digoxin is used orally in dose 0,25 mg (1 tab) 1-2 times daily. In case of positive result of therapy the daily dose of allapinin can be reduced to 50 mg (1 tablet 2 times a day) and digoxin - to the minimum effective one, which is 0,25 mg (1 tablet) once a day.
The criterion of such positive result of therapy is occurrence of the periods without paroxysms of tachyarrhythmia, which are greater than 1,5-2 periods. Such periods occurred earlier between paroxysms of tachyarrhythmia. Thus, this therapy provides prophylactic effect in respect to occurrence of tachyarrhythmia attack.
The significant advantage of this method is the possibility of using it for the patients with severe heart failure. Unlike the majority of other antiarrhythmic drugs of synthetic origin allapinin does not have any negative inotropic action in effective antiarrhythmic doses. For the patients with cardiac failure this cardiac glycoside leads to improving of metabolism in myocardial cells. Such improvement of myocardium metabolism contributes to the elimination of paroxysmal tachyarrhythmias
The most expressive impact of consolidated treatment is seen if there should arise an occurrence of intravenous organization of allapinin in single portion 30-40 mg and cardiovascular glycoside in 20-30 minutes subsequent to utilizing allapinin. Such blend of these specialists is molded by their pharmacodynamics. The start of antiarrhythmic impact happened uniquely in 10-15 minutes after its intravenous organization. The maximal impact of allapinin is accomplished in 20-40 minutes in the wake of utilizing this antiarrhythmic tranquilize. This property of allapinin is molded when of intravenous organization of heart glycoside. Such treatment was acknowledged with 37 patients having ischemic coronary illness and supraventricular paroxysmal tachyarrhythmias. They were remembered for the fundamental gathering of patients.
To control the viability of the joined treatment the monotherapy just utilizing intravenous organization of allapinin in single portion 40-50 mg was acknowledged with 38 patients having ischemic coronary illness and supraventricular paroxysmal tachyarrhythmias.
The utilization of cardiovascular glycoside builds the antiarrhythmic impact of allapinin. This joined treatment is increasingly productive in examination with the monotherapy with the assistance of just a single readiness (allapinin). Such joined utilization of these two medications adds to shortening of the time, which is required for concealment of tachyarrhythmia eruption. After the restore of the typical sinus beat the supporting treatment (oral organization of allapinin and cardiovascular glycosides) must be controlled in the most punctual conceivable period
