Pulse amplitude shifts with ectopy may aid non-invasive LV timing estimates; leaves open prospective validation before clinical use.
Can peripheral pulse amplitude measured by photoplethysmography determine aortic valve opening time and left ventricular peak filling rate in patients with ectopic beats?
Photoplethysmography can non-invasively estimate aortic valve opening time and left ventricular peak filling rate by analyzing peripheral pulse amplitude changes during ectopic beats.
Zheng et al. (2008) studied this question.
