Method and system for using multiple intravascular sensing devices to detect electrical activity

摘要

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 such as a catheter or guidewire having a plurality of sensing electrodes on a distal portion thereof which is disposed within one location of the patient's coronary vasculature and a second intravascular device such as a catheter or guidewire having a plurality of sensing electrodes on a distal portion thereof which is disposed within a second location of the patient's coronary vasculature to facilitate mapping the electrical activity of the patient's heart. Once the electrical activity has been mapped, therapeutic procedures can be initiated.
