摘要：
A method and system are provided for characterizing chamber specific function. The method and system comprise collecting cardiac signals associated with asynchronous timing between first and second chambers of the heart； collecting dynamic impedance (DI) data along a chamber-specific function (CSF) vector to form a DI data set, the DI data set collected during a collection window that is temporally aligned based on a timing feature of interest (FOI)； repeating the collection operations over multiple cardiac cycles (CC) to obtain an ensemble of DI data sets； and combining the ensemble of DI data sets to form a composite DI data set that is coupled to a chamber functional mechanic of interest (FMOI) associated with the first chamber and decoupled from functional mechanics associated with the second chamber； and analyzing the composite DI data set to obtain a CSF indicator associated with the chamber FMOI of the first chamber.
