A minimum heart rate of 35 beats per minute is common in severe sinus bradycardia, sick sinus node syndrome, and high degree of atrioventricular block, and treatments include medications such as the use of drugs like atropine and isoproterenol, and surgical treatments such as implantation of a pacemaker.
Patients with sinus bradycardia, sick sinus node syndrome, and high atrioventricular block experience severe bradycardia, which can lead to symptoms such as fainting, and sudden death can occur if not treated correctly and in a timely manner. Drugs such as atropine or isoproterenol can be applied to increase the heart rate, but the long-term effects of the application are uncertain, and are prone to serious side effects, so cardiac pacemaker therapy is recommended.
Permanent pacemakers are the fundamental treatment for slow heart rate. Pacemakers are used to treat arrhythmia by issuing certain forms of electrical impulses to stimulate the heart to agitate and contract, mimicking the formation and conduction of impulses in a normal heart.
With a minimum heart rate of 35 beats, patients are advised to seek medical attention as much as possible to clarify the cause and actively diagnose and treat the condition.
