Overview
Common risk factors associated atioventricular block include older age, male sex, history of myocardial infarction, history of congestive heart disease, high systolic blood pressure, increased fasting blood glucose level.
Risk Factors
- Common risk factors associated with atioventricular block include:[1]
- Older age
- Male sex
- History of myocardial infarction
- History of congestive heart disease
- High systolic blood pressure
- Increased fasting blood glucose level
- Common risk factors associated with atrioventricular block after cardiac surgery include:[2]
- Older age
- Atrial fibrillation
- Prior surgery
- Preoperative renal failure
- Active endocarditis
- Common risk factor associated with intraoperative bradycardia and hypotension in patients undergoing non-cardiac surgery include:[3]
- Age (>60-65 years of age)
- Comorbidities
- Lower heart rates (<60 bpm) or blood pressure (<110/60 mm Hg) at baseline
- Use of concomitant drugs such as beta-blockers, renin-angiotensin system blockers
- Preoperative RBBB
- Multivalve surgery , especially tricuspid valve
- Preoperative LBBB
- Preoperative PR interval >200 ms
- Prior valve surgery
- Age >70 years
- Reoperations
- Longer times of cross-clamp
- Absence of preoperative sinus rhythm
