RCA lesions associate with chronotropic incompetence in ischemia; hypothesis-generating and should not yet change practice or testing interpretation.
Is chronotropic incompetence associated with specific wall motion abnormalities and coronary arterial lesions in patients with ischaemia?
Chronotropic incompetence in patients with ischaemia is associated with worse ventricular dysfunction during peak exercise and critical right coronary artery lesions.
Anjos-Andrade et al. (2010) studied this question.
