Heart ablation is moving beyond heat and cold, and the medtech race is getting much bigger

Pulsed field ablation is changing atrial fibrillation treatment by using extremely short electrical pulses to disrupt targeted cardiac cells instead of relying primarily on heat or freezing. Boston Scientific, Medtronic, Abbott Laboratories and Johnson & Johnson now compete across multiple FDA-approved PFA platforms, while new trials are pushing the technology into persistent atrial fibrillation, broader lesion sets and potentially earlier treatment.
