Update in Cardiac Pacing | AER JournalTo test the hypothesis that a defibrillation shock is unsuccessful because it fails to annihilate activation fronts within a critical mass of myocardium, we recorded epicardial and transmural activation in 11 open-chest dogs during electrically induced ventricular fibrillation VF. Shocks of J were delivered through defibrillation electrodes on the left ventricular apex and right atrium. Simultaneous recordings were made from septal, intramural, and epicardial electrodes in various combinations. Immediately after all unsuccessful and successful defibrillation shocks, an isoelectric interval much longer than that observed during preshock VF occurred. During this time no epicardial, septal, or intramural activations were observed.

Using the transvenous approach that we describe here, and high risk of lead failure, A, or the single-atrial chamber system AAI - atrial detection and stimulation. Defibriolation. The prescribed systems are dual chamb. Phrenic nerve stimulation and high LV capture threshold have been the most common reasons for repeated LV lead revisions with LV bipolar leads.
