"Is It Normal to Not Have a Sinus Rhythm?"

Non-sinus rhythm is typically abnormal, with causes including medication factors, organic diseases, and more. Non-sinus rhythms encompass premature beats and tachycardia, among others. Treatment typically varies based on the underlying cause. Normal heart rate is sinus rhythm; when sinus node dysfunction arises from various reasons, the heart rate of other pacemakers becomes ectopic and is considered abnormal. Causes encompass both medication factors and organic diseases. Medication factors include the use of digitalis drugs, quinidine, and others. Organic diseases include acute myocardial infarction, dilated cardiomyopathy, myocarditis, and so on. Non-sinus heart rates include atrial premature beats, ventricular premature beats, atrial fibrillation, supraventricular tachycardia, atrial flutter, and more. Clinically, antiarrhythmic medications such as metoprolol, lidocaine, propafenone, and amiodarone are selected based on the patient's specific condition. Radiofrequency ablation may also be considered depending on the condition. Upon experiencing arrhythmia, immediate consultation with a cardiologist and completion of auxiliary examinations for targeted treatment is crucial.
