BACKGROUND: This study aims to compare the image quality of second generation versus first generation 320-computed tomography coronary angiography (CTCA) in patients with heart rate >/=65 bpm as it has not been specifically reported. METHODS: Consecutive patients who underwent CTCA using second-generation-320-detector-row-CT were prospectively enrolled. A total of 50 patients with elevated (>/=65 bpm) heart rate and 50 patients with controlled (/=65 bpm) compared to first generation CT scanner.
