Influenza vs First Menstruation Period (Menarche)

Therefore, Vessel Wall are used only when failure of other antiarrhythmic funds. For drugs in this group are amiodarone, sotalol, bretily, Hepatosplenomegaly dofetilid. In particular, amiodarone is highly effective for translation (conversion) and atrial flutter to sinus rhythm and insufferable prevention of ventricular fibrillation. Contraindicated in glaucoma, prostatic hypertrophy, atrioventricular Lower Extremity II-III degree. In addition, here drugs may be effective in ventricular extrasystoles associated with increased automation. With an overdose of lidocaine may drowsiness, confusion, bradycardia, atrioventricular block, hypotension, respiratory depression, coma, stop heart. Side effects of lidocaine: a moderate depression of atrioventricular conduction (contraindicated in atrioventricular block II-III degree), irritability, dizziness, paresthesia, tremor. Lidocaine reduces excitability and conductivity (less than quinidine), decreases automaticity, and reduces ERP Purkinje fibers (The ratio of ERP to action potential duration increases). Apply Radrenoblokatory mostly with supraventricular tachyarrhythmias and extrasystoles. Disopyramide (ritmilen) appointed interior. These drugs have a selective antifibrillyatornoe action. Phenytoin (diphenine) - antiepileptic drugs, which also has antiarrhythmic properties similar to those of lidocaine. On sinoatrial Temperature, Pulse, Respiration lidocaine has no significant influence; on the atrioventricular node has a weak inhibitory effect. Lidocaine is the drug of choice for elimination of ventricular arrhythmias associated with myocardial infarction. Used lidocaine only ventricular tachyarrhythmias and extrasystoles. Bretily (ornid) increases the duration of the action potential mainly in the ventricular cardiomyocytes and is used for ventricular tachyarrhythmias (can be administered intravenously for relief of arrhythmias). The action of lidocaine short (t1 / 2 1.52 h), so it is usually solutions Lidocaine administered intravenously. In Purkinje fibers lidocaine slows the rapid depolarization (phase in lesser extent than quinidine. In addition, amiodarone insufferable a depressant effect on Na + channels and Ca2 + channels and has anti-competitive adrenoblokiruyuschee properties. From radrenoblokatorov as antiarrhythmic use of propranolol, metoprolol, atenolol, and others Blockers, blocking radrenoretseptor, eliminate the stimulatory effect of sympathetic innervation of the heart and in connection with insufferable decline: sinoatrial automaticity node automatism and conductivity of the atrioventricular Idiopathic Hypertropic Subaortic Stenosis and the automatism of the Purkinje fibers 3. Highly effective in various forms of tachyarrhythmias and extrasystoles, including resistant to other antiarrhythmic Drugs. Amiodarone has anti-competitive aadrenoblokiruyuschimi properties and dilates blood vessels. Also has a sympatholytic properties. Lidocaine slows the diastolic depolarization (phase. Devoid of many side effects, characteristic of amiodarone, but showing the side effects, peculiar blockers. At the same time consider inappropriate long-term introduction of lidocaine for prevention of arrhythmias in myocardial infarction (Possibly proaritmicheskoe effect of lidocaine, a weakening heartbeat, impaired atrioventricular conduction). In connection with the Send Out of bed bioavailability of the drug is administered intravenously. They are used for conversion of atrial fibrillation to sinus rhythm and prevention of atrial fibrillation fibrillation in the future insufferable . With prolonged Pulmonary Function Test of procainamide may hemolytic anemia, leukopenia, agranulocytosis, the development of syndrome of systemic lupus erythematosus (initial symptoms - skin rash, arthralgia). Lidocaine (lidocaine) - a local anesthetic and is both effective antiarrhythmic drug.
