静息心率对急性心肌梗死患者心功能的影响及护理

The effect and nursing of resting heart rate for heart function of acute myocardial infarction patients

目的探讨静息心率(resting heart rate,RHR)对急性心肌梗死(acute myocardial infarction,AMI)患者心功能的影响及护理方法。方法选择住院确诊的AMI患者60例,根据RHR分为心率正常组RHR1(RHR<80次/分)19例和心率增快组RHR2(RHR≥80次/分)41例。所有患者入院后均应用倍他乐克控制心率。结果入院时未应用倍他乐克治疗前,RHR1组的心功能好于RHR2组(P<0.05);应用倍他乐克后,RHR1组的19例患者及RHR2组的41例患者的心功能均较前明显好转(P<0.05)。结论降低静息心率对急性心肌梗死患者的心功能有保护作用,可改善心肌供血,提高患者生活质量。

Objective： To discuss the effect and nursing of resting heart rate for heart function of acute myocardial infarction patients.Methods： 60 patients with AMI were divided into two groups according to RHR,19 patients of normal heart rate RHR1（RHR80 bpm）were in one group and 41 patients of rapid heart rate RHR2（RHR≥80 bpm） were in another group.Betaloc was applied to control heart rate for all patients after being admitted to hospital.Results： The heart function of the patients of RHR1 was superior to those of RHR2 before applying Betaloc（P0.05）.However the heart function of RHR1 and RHR2 was significantly improved after Betaloc（P0.05）.Conclusion：For acute myocardial infarction patients,reducing resting heart rate can protect the heart function,improve myocardial blood supply and increase the living quality.
