Abstract

A method and system for detecting electrical activity within a patient's heart, particularly the electrical activity which causes arrhythmia, which includes a first intravascular device (40) such as a catheter or guidewire having a plurality of sensing electrodes (15) on a distal portion (14) thereof which is disposed within one location of the patient's coronary vasculature and a second intravascular device (11) such as a catheter or guidewire having a plurality of sensing electrodes (17) on a distal portion (16) thereof which is disposed within a second location of the patient's coronary vasculature to facilitate mapping the electrical activity of die patient's heart. Once the electrical activity has been mapped, therapeutic procedures can be initiated.
