The value and accuracy of intracoronary electrocardiogram in the diagnosis of myocardial ischemia in coronary heart disease.

Background: Although intracoronary electrocardiography (IC-ECG) offers direct electrophysiological insights into myocardial ischemia caused by insufficient coronary blood supply, compared to common diagnostic methods like electrocardiography (ECG), it lacks widespread adoption and robust clinical research.

Objective: To analyze the value and accuracy of intracoronary electrocardiogram in myocardial ischemia diagnosis in coronary heart disease patients.

Methods: Three hundred patients treated at our hospital were included in the study.
