fast pacing

A term defined in the context of implantable pacemakers for the delivery—e.g., atrial burst pacing—of rapid, multiple electrical pulses, to pace the heart faster than its intrinsic rate. Fast pacing is used for ventricular tachycardia, to try to break the tachycardia before it progresses to ventricular fibrillation.

The magnet usage with implantable cardioverter-defibrillators (ICD) excludes detection and therapy of ventricular arrhythmias (anti-tachycardia pacing and shocks), whereas the use of magnet does not affect anti-bradycardia pacing.
Various mechanisms could explain the tachycardia; to us a plausible one is an ectopic automatic focus in the left side of the ventricular septum with the anti-tachycardia pacing changing the depolarization pathway of the ventricular tachycardia by concealed conduction into the pathway(s).
Additionally, the advanced sensing technology designed to avoid sensing unwanted signals (T-waves) and offer more anti-tachycardia pacing options, which can convert many fast ventricular arrhythmias painlessly and avoid the need for high voltage shocks.
Potentially life-threatening ventricular tachyarrhythmias were appropriately aborted, either by anti-tachycardia pacing or ICD shock, after a median follow-up of 36 months in patients with implanted devices for secondary prevention (10, 11).
reported that the all-cause mortality of patients in the MADIT II trial who received appropriate and inappropriate shocks (but not anti-tachycardia pacing [ATP]) was 4 times higher than for those without shock therapy.
The device is fully programmable for treating ventricular tachyarrhythmias with shock therapy, but does not provide anti-tachycardia pacing, Mr.
With a view to interrupting the arrhythmia, the ICD can fire a burst of pulses at a frequency that is faster than the spontaneous heart rate, in order to "capture" the tachycardia and stop it (the "anti-tachycardia pacing" ATP).
