Postpacing T-wave changes may indicate ischemia in VVI patients; hypothesis-generating and requires prospective confirmation before practice change.
Are postpacing T wave changes associated with myocardial ischemia in patients with ventricular demand pacemakers compared to normal controls?
Postpacing T wave changes in patients with ventricular demand pacemakers are closely associated with myocardial ischemia as evidenced by thallium perfusion defects.
Hamada et al. (1995) studied this question.
