Clinically, there is no such thing as the best way not to have a pacemaker. Whether or not a pacemaker is needed depends on the patient’s specific condition. A pacemaker is an artificial device that can mimic the formation and conduction of normal heart impulses. It is capable of delivering certain electrical impulses to stimulate the heart to beat in order to treat cardiac dysfunction caused by certain arrhythmias, and is one of the most important interventional treatments for cardiac arrhythmias. Indications include: symptomatic cardiac chronotropic insufficiency, pathological sinus node syndrome or atrioventricular block with clear symptoms, ventricular rate less than 50 beats/min, chronic two- or three-branch block with second-degree type II, high or intermittent third-degree atrioventricular block, irreversible high or third-degree atrioventricular block after cardiac surgery, and high or third-degree atrioventricular block caused by neuromuscular disease. Cardiac pacemakers can be used to prevent and treat malignant arrhythmias caused by long QT interval syndrome, assist in the treatment of hypertrophic cardiomyopathy, dilated cardiomyopathy, intractable heart failure and so on. Temporary pacemakers can also be used in some patients with acute infarction combined with atrioventricular block. Cardiac pacing therapy is a very important means of treatment for many heart diseases, patients who meet the indications should be used as soon as possible under the condition of no contraindications, do not easily certain claims without scientific basis, so as not to delay the condition, specific can consult a professional physician’s opinion.
