Sudden cardiac death is often associated with arrhythmia, which affects over three million people each year in the United States. These patients are at increased risk of stroke, heart attack, heart failure, and sudden cardiac death. Risk of developing an arrhythmia can be determined through the identification of cardiac conduction abnormalities, but that method falls short of monitoring the health of the cardiac tissue itself.
Measuring the conduction velocity of electrical impulses through heart tissue determines the health of that tissue. A standard clinical loop catheter is used to extract longitudinal and transverse conduction velocities. These velocities are indicative of various disease states, providing clinicians with the exact location of diseased tissue to improve patient treatment plans. A map of where the diseased tissue resides in the heart is generated for reference during the procedures, enhancing the treatment of heart defects, such as atrial fibrillation.
