Clinician-controlled modifiers that increase cardioversion success

Clinician-controlled modifiers of successProposed mechanism
Energy intensity (joules provided)Increased cardiac energy delivery
Form of energy (biphasic vs monophasic)Two vectors of current flow
Pad position (anterolateral vs anteroposterior)Increasing atrial energy delivery
Chest pressure (placed on the anterior pad)Decreased transthoracic impedance
