Heart rate may confound intraoperative diastolic indices in cardiac surgery; leaves open whether serial LV measurements require rate standardization.
Does pericardial opening, atrial pacing, or increased heart rate alter left ventricular systolic and diastolic function measurements in patients undergoing coronary artery surgery?
Pericardial opening and atrial pacing do not alter intraoperative LV function measurements, but increased heart rate inconsistently affects diastolic indices, suggesting serial measurements should be performed at similar heart rates.
Royse et al. (2003) studied this question.
