干预措施:

择日行脊髓神经电刺激治疗,一期置入刺激电极及延长导线,Tonic 刺激模式完成测试(术中测试电极触点刺激范围覆盖心绞痛疼痛区域),二期(一周左右后)置入永久刺激器。给予持续 Burst 模式电刺激(刺激参数:Burst 刺激频率 500Hz,脉宽50us,电流 0.05mA,每分钟爆发刺激 40 次)。观察 1 个月、3 个月、6 个月、12 个月、24 个月患者心绞痛症状及相关临床指标的变化。 术后第 3 个月,如患者中重度心绞痛(VAS>4)发作次数减少 50%,患者可根据自身感受,选择继续 Burst 刺激模式,或调整为 Tonic 刺激模式(医生设置好参数后,可由患者使用患者程控仪自行切换调控)。

干预措施代码:

Intervention:

Spinal cord nerve stimulation therapy was performed on the selected day, the first stage was implanted with stimulation electrodes and extension leads, the Tonic stimulation mode was completed (the intraoperative electrode contact stimulation range covered the angina pain area), and the second stage (about a week later) was implanted with a permanent stimulator. Continuous Burst mode electrical stimulation was administered (stimulation parameters: Burst stimulation frequency 500Hz, pulse width 50us, current 0.05mA, 40 burst stimulation per minute). The changes in angina symptoms and related clinical indicators in patients at 1 month, 3 months, 6 months, 12 months, and 24 months were observed. In the 3rd month after surgery, if the number of episodes of moderate to severe angina pectoris (VAS>4) is reduced by 50%, the patient can choose to continue the Burst stimulation mode or adjust to the Tonic stimulation mode according to his or her own feelings (after the doctor sets the parameters, the patient can switch the control by using the patient's program controller).
