Excerpt

Chronotropic incompetence (CI) is defined as the inability to reach 85% maximum predicted heart rate (MPHR) at maximal exercise in the absence of negative chronotropic agents.1 This finding has been reported as an adverse prognostic indicator in patients with and without known coronary artery disease.2 We present two patients presenting with chest pain symptoms who had severe CI as a manifestation of ischemia during exercise that subsequently reversed with revascularization. …
