[Clinical investigation of temporary heart pacemaker for emergency treatment of patients with acute and severe cardiovascular diseases].

ABSTRACT

Objective: To investigate the clinical efficacy and safety of temporary heart pacemaker for emergency treatment of patients with acute and severe cardiovascular diseases. Methods: The clinical data of 147 patients with cardiac arrest or bradyarrhythmia from August 2007 to December 2015, was analyzed retrospectively in Department of internal and Emergency Medicine, People's Hospital of Henan. Based on the rescue methods, all patients were divided into two groups observation group (80 cases, among whom, 49 cases with cardiac arrest and 31 cases with bradyarrhythmia) and control group (67 cases, among whom 39 cases with cardiac arrest and 28 cases with bradyarrhythmia). Patients in observation group received temporary heart pacemaker, and patients in control group received traditional cardio-pulmonary resuscitation and drug treatment. The rate of rescue and complications were analyzed and compared in two groups. Results: The total rescue rate in observation group was 96.3%, which was significantly higher than that in control group (44.8 %) (P<0.05). Further analysis showed that the rescue rate of patients with cardiac arrest in observation group was significantly higher than that in control group (95.1% vs 45.1%) (P<0.05), and the rescue rate of patients with bradyarrhythmia in observation group was significantly higher than that in control group (97.4% vs 44.4%) (P<0.05). Complications were observed in 4 patients pericardial effusion (1 case ), ventricular fibrillation (1 cases) and catheter dislocation (2 cases). Conclusion: Temporary heart pacemaker was safe and effective in the treatment of patients with acute and severe cardiovascular diseases with improved rescue rate.
