IMPLANTABLE SUBCUTANEOUS MEDICAL DEVICE PROVIDING POST-EXTRA-SYSTOLIC POTENTIATION THERAPY

摘要

An ICD system adapted for subcutaneous implantation, the system comprising: a pair of electrodes adapted to deliver electrical stimulation to a heart; a set of low polarization electrodes for sensing a response to electrical potentiation pulses delivered from the first pair of electrodes; and a counter for logging a duration of fast VT and VF between high voltage shocks that restore normal sinus rhythm to the heart, the shocks delivered by the first pair of electrodes.
