A method for selecting images for coronary analysis using time stamps to correlate cardiovascular images to corresponding physiological or hemodynamic monitoring, e.g., ECG, data. The method uses time stamps that are intrinsic to a distributed network clock synchronization protocol for correlation of images and data. A coronary analysis system is employed to correlate images with physiologic data, e.g., using time stamp data as well as offset data derived using the distributed network clock synchronization protocol.
