The preferred therapeutic agent for supraventricular arrhythmias is a calcium channel blocker, and the application of verapamil for intravenous pushing can be considered. In addition, if the patient has significant supraventricular arrhythmias with frequent episodes, they can be controlled by controlling the triggers, and if they remain symptomatic after elimination of the triggers, they can be controlled by applying verapamil or by applying beta-blockers such as betalactam. If the patient has recurrent and frequent supraventricular arrhythmias, they can be controlled by surgical treatment with radiofrequency ablation. Alternatively, oral medications can be used to prevent thromboembolism. If patients have paroxysmal supraventricular arrhythmias, the preferred medication remains the calcium channel blocker verapamil, or, if this is not effective, amiodarone and lidocaine can be used as adjunctive therapy.
