About

INTRINSIC RV is a two-armed randomized trial that will compare the effects of innovative dual-chamber pacing with AV Search Hysteresis to standard VVI among ICD patients.

Full description

The purpose of study is to assess whether AVSH will provide benefits of a dual-chamber ICD without the deleterious effects of unnecessary RV pacing. This study will aim to demonstrate that DDDR-AVSH is equal to VVI with respect to mortality and HF hospitalizations.
