[Applications of retrospective electrocardiogram editing in dual-source computed tomography coronary angiography in patients with arrhythmia].

Objective: To evaluate the clinical value of retrospective electrocardiogram (ECG) -editing technique in dual-source computed tomography (CT) coronary angiography in patients with arrhythmia.

Methods: Totally 73 patients with arrhythmia during dual-source CT coronary angiography were included into this study. A retrospective gating technique and ECG-editing technique (Insert Sync; Disable Sync; Delete Sync; Shift R-peak) were used in patients who needed ECG-editing.
