If a patient has an accelerated heart rate after surgery, this is a relatively normal phenomenon, and a person may experience an accelerated heart rate under stressful conditions. If necessary, patients are advised to take oral sympathetic excitatory drugs to slow down the heart rate, for example, patients are advised to take drugs like betalac or bisoprolol, which can help to lower the heart rate and improve the symptoms of panic and palpitations. Patients are also advised to relax more and gradually this rapid heart rate will improve. If the patient is currently in atrial fibrillation, he should be treated with a combination of amiodarone to reset the sinus rhythm, in addition to oral betalocort to further control the heart rate.
