The invention provides a system for evaluating a patient featuring: 1) an ECG-measuring system connected to the patient and configured to sense ECG information from the patient 2) a data-acquisition system interfaced to a vital sign-monitoring system configured to sense vital sign information from the patient during an electro-physiology (EP) procedure and 3) an external software system interfaced to both systems. The external software system includes a first software interface that receives ECG information measured from the patient by the ECG-measuring system, and a second software interface that receives vital sign and EP-related information from the data-acquisition system measured from the patient during an EP procedure. A database stores physiological and EP-related information measured from the patient before, during, and after the EP procedure. And an algorithm interfaced with the database determines an efficacy of the EP procedure by collectively analyzing information measured during each of these phases.
