Devices, systems and methods are provided for treating target tissue with pulsed electric field energy in a manner that does not induce cardiac arrhythmias such as fibrillation of the heart and therefore negates any need for cardiac synchronization of energy delivery. Cardiac synchronization is typically employed to avoid delivering energy during portions of the cardiac cycle that are vulnerable to inducing fibrillation. Thus, herein parameters are manipulated to reduce the probability of inducing an arrhythmia. Typically, high voltage energy can trigger a premature action potential within the cardiac muscle as the delivered energy increases the cardiac muscle cell membrane permeability allowing ion transport, which can induce cardiac arrhythmias, especially ventricular fibrillation. However, both shorter pulse durations (i.e. higher frequencies such as 100-600 kHz) and biphasic waveform shapes theoretically and practically reduce the probability of inducing an arrhythmia.
