Pulsed field displaces thermal energy in atrial fibrillation
Pulsed field ablation delivers high-voltage microsecond pulses that kill cardiac myocytes by electroporation while largely sparing oesophagus, phrenic nerve, and pulmonary vein tissue. Boston Scientific's Farapulse, Medtronic's PulseSelect and Sphere-9, Johnson & Johnson's Varipulse, and Abbott's Volt have all reached commercial launch in the United States or Europe. Conversion has been unusually fast for medical devices: centres that adopted early moved most of their atrial fibrillation volume across within four quarters. Thermal radiofrequency retains complex atrial and ventricular work, where point-by-point lesion control still matters more than speed. That division of labour looks reasonably durable.
