Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

pacemaker dependent patients after cardiac surgery

Pacemakers are widely used in cardiotomy patients, while it's common that the patients happen to be pacemaker dependent. When the doctor decides to set the heart rate of the pacemaker, we record the hemodynamic parameters and peripheral perfusion index from 70-80-90-100-110 bpm.

No interventions assigned to this group
