Easing the Heart Back to Normal Rhythm (3 of 8) (VIDEO)
Caption
Caption and credit information, second row, left to right: High frequency alternating current electric fields slows then terminates an arrhythmia in cardiac tissue. The top panel is a map of the electrical activity, and the bottom panel is the electrical activity at the site shown in the map. A rapid arrhythmia was initiated in cardiac tissue. After one second, a high frequency electric field is applied, and the strength of the field gradually increases with time. The arrhythmia gradually slows down, and then is eventually terminated. After the field is turned off, no electrical activity is present. This video relates to a paper that appeared in the Sept. 28, 2011, issue of Science Translational Medicine, published by AAAS. The paper, by Dr. Hari Tandri of Johns Hopkins University in Baltimore, MD and colleagues, was titled, “Reversible Cardiac Conduction Block and Defibrillation with High-Frequency Electric Field.”
