Abstract | BACKGROUND: HYPOTHESIS: This study investigated the mechanisms and outcome of VT associated with cardiac sarcoidosis. METHODS: The study included eight consecutive patients (five men, three women, aged 54 +/- 19 years) who had sustained monomorphic VT associated with cardiac sarcoidosis in our hospital. RESULTS: The average ejection fraction was 43 +/- 11%. Twenty-two VTs were observed in these patients, and mean heart rate during VT was 192 +/- 29 beats/min (range 144-259). The phenomenon of transient entrainment was documented in 10 of 22 (45%) VTs by ventricular pacing (eight in the active phase). Another five (23%) VTs could not be entrained, but could be initiated by programmed stimulation and terminated by rapid pacing, reproducibly. In 3 of the 22 (14%) VTs, cardioversion was required urgently because of the fast rate, while the remaining 4 (18%) could be induced during electrophysiologic study. CONCLUSIONS:
