15. Ventricular Arrhythmias

Show Summary Details

Preview

We considered 51 patients with St. Jude Medical Implantable Cardioverter Defibrillators (ICDs) in secondary prevention. The average follow-up was 25 months. 34 subjects had coronary artery disease (CAD group), average ejection fraction (EF) = 35%; 17 had dilated cardiomyopathy (DCM group), average EF = 32%.

Results

35 patients did not have sustained ventricular tachyarrhythmias (VTs), while 16 of them had 79 spontaneous VTs: 7 from CAD group (21%) had 19 VTs, and 9 from DCM group (53%) had 60 VTs. We observed 3 modes of VT onset: (i) premature ventricular contraction consisting of 13 episodes from CAD group and 35 from DCM group; (ii) PVC preceded by a short-long-short cycle with 5 VTs from CAD group and 15 from DCM group; (iii) paced beats immediately after PVC pause with 1 VT from CAD group and 10 from DCM group. Finally 4 patients, all of them from DCM group, had more than 1 mode of VT onset.

Conclusions

DCM patients present more VTs, and CAD patients have more homogeneous modes of onset.
