Arrest time: RR interval The number of arrests greater than 2000ms is 1; the longest RR interval: 2204, occurrence time: 09:26:26, 1. 2.What treatment plan should be taken? 3.Is the medication effective? According to the information you provided, the diagnosis of sinus syndrome is clear, and there is little change in the comparison of the two results. When to install a pacemaker is mainly based on the symptoms. If you have symptoms, you should operate as soon as possible, and if you do not have symptoms, you should pay attention to regular follow-up.
