US Patent 7676266 Monitoring ventricular synchrony

An exemplary method includes providing a maximum right ventricular systolic pressure value and corresponding time during a cardiac cycle, providing a left ventricular displacement value for the corresponding time, determining a product of the maximum right ventricular systolic pressure value and the magnitude of the left ventricular displacement value and assessing ventricular synchrony for the cardiac cycle based at least in part on the product. Such a method may include adjusting one or more cardiac pacing parameters based at least in part on the product. Other exemplary methods, devices, systems, etc., are also disclosed.
