Electromechanical mapping of the heart

Electromechanical endocardial mapping of the heart using a nonfluoroscopic catheter-based system is a new imaging modality that has been studied recen tly in the experimental setting as well as in patients, Besides its origina l application in the diagnosis and treatment of various cardiac arrhythmias , it has also been used as an investigational tool for assessing left ventr icular function and viability. Finally, the mapping system may be a valuabl e platform for direct myocardial revascularization using either laser treat ment or injection of pharmacologic agents.
