Observational (n=24)
Does echocardiography-guided pacemaker optimization improve cardiac output in adult patients following cardiac surgery?
Echocardiography-guided heart rate optimization significantly improves cardiac output compared to standard clinically derived pacing settings in the immediate postoperative period after cardiac surgery.
Answers are grounded in this paper and cite their sources.
May support echo-guided rate optimization to augment perioperative output; leaves open effects on clinical outcomes in cardiac surgery.

Tavazzi et al. (2017) conducted an observational in postoperative cardiac surgery (n=24). Echocardiography-guided heart rate optimization vs. Clinically derived pacing settings (clinician set RR interval) was evaluated on Cardiac output and cardiac index (p=<0.001). Echocardiography-guided heart rate optimization significantly increased cardiac output (by 2.21 L/min) and cardiac index in 79% of postoperative cardiac surgery patients (p<0.001).
