Abstract
A defibrillator connected by catheters (7) to the heart (6) has an external circuit (2, 12) connected to a passive implanted circuit (5) by transdermal induction via voils (3, 4). For atrial defibrillation, pulses of 3–4 J can be transmitted at about 7 MHz without damage, using an implanted coil (4) of 20 mm diameter.
