May warrant permanent pacing in AMI with RBBB, left-axis deviation, and transient heart block; leaves open confirmation by randomized trials.
Does permanent pacing prevent late sudden death in patients with acute myocardial infarction complicated by transient complete heart block, right-bundle-branch block, and left-axis deviation?
Transient complete heart block in AMI patients with right-bundle-branch block and left-axis deviation carries a high risk of late sudden death, which may be prevented by permanent pacing.
Atkins et al. (1973) studied this question.
