Images recorded by the ECG monitoring system in the intensive care unit within the first hour after the initial out-of-hospital episode of abortive sudden cardiac death. Ventricular fibrillation was recorded from patients, following admission to cardiac ICU.

The patient was resuscitated by her husband until the emergency services arrived when ventricular fibrillation (VF) was registered (Figure 1).
(A) Representative ECG from telemonitoring, single monomorphic ventricular ectopic complexes. (B) Representative ECG from telemonitoring. Unstable episodes of the monomorphic idioventricular rhythm with frequency of 81 bpm are observed.

Single monomorphic ventricular ectopic complexes (n = 3,185) were found mainly in the daytime, and 11 unstable episodes of the monomorphic idioventricular rhythm with an average frequency of 92 bpm were registered for the entire period of telemonitoring (Figures 2A,B).
Single monomorphic ventricular ectopic complexes during and at the peak of stress echocardiography.

Stress echocardiography performed several months later demonstrated high exercise tolerance and no myocardial ischemia, but at the peak of physical activity, single ectopic ventricular complexes were registered (Figure 3).
