About

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.

Full description

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.

Enrollment: 50 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• age >=18 years old;
• postcardiotomy
• placement of temportary pacemaker during the surgery
• dependence of pacemaker (abscence of autonomic cardiac rhythm）

Exclusion criteria

• hemodynamic unstable （high dose of vasoactive drugs）
• fingers ischemia, cannot monitor the peripheral perfusion index

Trial design

50 participants in 1 patient group

pacemaker dependent patients after cardiac surgery

Description:

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.
