Every ablation energy does one job: push a volume of myocardium past an injury threshold, through the
whole wall, and stop short of what lies beyond. DC shock, RF, cryo and pulsed field differ only in what they deliver
and what holds them back.
One engine sits under every module: a slice through catheter, blood and wall, solved live. Set the power, the
contact, the flow or the freeze, and watch the lesion form. It starts with the defibrillator that began catheter
ablation and the four pieces of physics underneath every energy, works through the catheters themselves — their tips, curves and force sensors — and ends at the field that
kills without heat.
