A false positive ischemia result in a stress test occurs when the test indicates the presence of ischemia (reduced blood flow to the heart) despite there being no actual coronary artery disease. This can happen due to factors such as abnormal heart rhythms, technical errors, or individual variations in heart response to stress. Conditions like left bundle branch block or prior myocardial infarction can also lead to misleading results. Clinicians often corroborate stress test findings with further imaging or diagnostic procedures to confirm the presence of ischemia.
