The duration of treatment depends on the form of arrhythmia, the effectiveness of the preparation, and its tolerability. Side effects Cardiovascular system: AV block, intraventricular conduction disturbances, right bundle branch block, decreased myocardial contractility, decreased coronary blood flow. Arrhythmogenic effect develops rarely. CNS: dizziness, accommodation disturbances. Gastrointestinal tract: nausea. Contraindications Hypersensitivity to the preparation and its components Cardiac conduction disturbances: sinoatrial block of II degree, atrioventricular block (AV) of II and III degree, severe intraventricular conduction disturbances Arterial hypotension Severe forms of heart failure Liver and kidney dysfunction Pregnancy and lactation When prescribing the preparation during pregnancy or lactation, the potential benefit to the mother and the expected risk to the fetus should be considered.
