Multicenter Study Observational Study
Noninvasive monitoring of stroke volume with resynchronization devices in patients with ischemic cardiomyopathy.
A novel method to estimate cardiac volumes based on impedance measurements using the leads of a resynchronization device has been developed. This study investigated the method in patients with ischemic cardiomyopathy and documented wall motion abnormalities. ⋯ In CRT patients with chronic infarction and wall motion abnormalities, impedance is a valid parameter to estimate stroke volume and to guide optimization of CRT timing.
