Abstract
ObjectiveThis study sought to evaluate the effectiveness of diltiazem at achieving a targeted heart rate (HR) of ≤75 bpm in orthotopic heart transplant patients during coronary computed tomography (CT) angiography. MethodsBaseline heart rates were compared to heart rates after diltiazem administration in 25 adult orthotopic heart transplant subjects being monitored by electrocardiogram (ECG) gaiting on a multidetector CT scanner. ResultsThe mean baseline HR of the group was 84.28 ± 11.305 bpm. After diltiazem administration, the mean heart rate of the group at the time of the coronary CT angiography study was 75.32 ± 9.49 bpm. Heart rates decreased in 23 subjects (92%) and the targeted heart rate of ≤75 bpm was observed in 13 subjects (52%). ConclusionDiltiazem administration was associated with a decrease in heart rate, yet reaching the targeted heart rate was limited. Further study regarding diltiazem dosing and its impact is warranted.
