简要总结
Pacemakers are widely used in postcardiotomy patients to avoid severe arrhythmia. The peripheral perfusion index (PI) has been considered as an effective parameter evaluating the circulation. In this study, investigators aim to avaluate the ability of peripheral perfusion index to detect changes of hemodynamics in postcardiotomy patients with pacemakers.
详细描述
Pacemakers are widely used in postcardiotomy patients to avoid severe arrhythmia. The peripheral perfusion index (PI) has been considered as an effective parameter evaluating the circulation. In this study, investigators aim to evaluate the ability of peripheral perfusion index to detect changes of hemodynamics (cardiac output or storke volume,et al) in postcardiotomy patients with pacemakers.
