A Percutaneous Catheter‐Based System for the Measurement of Potential Gradients Applicable to the Study of Transthoracic Defibrillation

Background: The local electric (E) field or potential gradient produced by a shock reliably predicts VF termination. In this study we evaluated a multiple electrode, catheter‐based device for closed‐chest 3D measurements of E field from transthoracic defibrillation shocks.
