Cardiac arrhythmias are heart rhythm abnormalities, where the heart beats too fast, too slow, or irregularly. Pharmacological therapy in patients with arrhythmias focuses on drug treatment to correct these heart rhythm disturbances. There are several medications that can be used to treat arrhythmias. They act on the heart’s various electrical channels to stop an irregular, extra electrical heart impulse or prevent abnormally fast electrical impulses from traveling along heart tissues. There are several classes of antiarrhythmics according to the ion channel they act on (Class I, sodium channel blockers; Class II, beta-blockers; Class III, potassium channel blockers; Class IV, nondihydropyridine calcium channel blockers). Each drug has its own benefits and risks, and the treatment prescribed will be based on the type of arrhythmia and the patient's general health. Close vigilance of the patient while receiving these drugs is necessary due to their potential toxicity.Up-to-date arrhythmia pharmacology is of paramount importance to physicians treating patients with heart diseases. Because there are numerous drugs available to treat arrhythmias, it is important for clinicians to understand the mechanisms of action, drug interactions, possible adverse reactions, and the appropriate indications for each drug's use. In addition, the Arrhythmia Pharmacology Update helps improve drug prescribing safely and effectively, while minimizing the risk of misdosing and harmful side effects. This could help reduce the incidence of cardiovascular adverse events and improve the quality of life of patients with arrhythmias. Finally, the update on the pharmacology of arrhythmias is essential to identify any new drugs in development or research, which could further improve the therapeutic efficacy and safety for patients suffering from these heart diseases.The scope of the Research Topic is to provide a practical update on the pharmacology of arrhythmias. Here are some examples of potential specific themes of interest: 1. Mechanisms of action of antiarrhythmic drugs 2. Side effects of antiarrhythmic drugs 3. Classification of antiarrhythmic drugs 4. Pharmacological therapy of supraventricular arrhythmias
