Abstract
Barotrauma from arc induced shock waves may result in dangerous sequelae during ablatian of arrhythmogenic foci. In this report, maximum pulse amplitude and pulse width determinations were made to assess, avoidance of shock‐wave generation using rectangular constant current pulses. Energy delivery appears to be optimal between 80–100 microseconds. If higher energies are required, multiple pulses will be needed to avoid barotrauma.Keywords
