A 55-year-old recipient of a Marquis VR single chamber ICD in the context of an old anterior myocardial infarction, 40% left ventricular ejection fraction (LVEF) and episode of VT at 200 bpm during electrical storms, was complaining of palpitations.
The PainFREE trials 1 and 2 confirmed the merit of programming a FVT (188 – 250 bpm) zone in ICD recipients. The ICD programming in this case was very similar to that recommended in these studies. It allows the use of ATP instead of shocks, which improves the quality of life.
VT, FVT via VF and VF detection zones with therapies were programmed. The combined counter detected 1 episode of FVT. This counter is used when the ventricular intervals straddle 2 detection zones, preventing delays in the detection of the episode. A burst of ATP terminated the tachycardia.
