Indicates autonomic imbalance during AMI exercise/recovery; hypothesis-generating for prognostic monitoring.
Does acute myocardial infarction alter autonomic modulation during exercise and recovery compared to healthy controls?
Patients with recent acute myocardial infarction exhibit altered autonomic modulation during early exercise and recovery, suggesting impaired parasympathetic withdrawal and sympathetic activation dynamics.
Chae et al. (1993) studied this question.
