Further study details as provided by LivaNova:

Primary Outcome Measures:
  • Percentage of patient with inappropriate shock [ Time Frame: 1 year ]
    device based data

Secondary Outcome Measures:
  • Appropriate shock [ Time Frame: 1 year ]
    device based data

Enrollment: 1013
Study Start Date: October 2011
Study Completion Date: February 2016
Primary Completion Date: August 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
ICD or CRT-D with PARAD+
only 1 arm is the study: all patients implanted with ICD or CRT-D with PARAD+ enabled, no comparator
Device: PARADYM DR model 8550; PARADYM CRT model 8750; PARADYM RF DR model 9550; PARADYM RF CRT model 9750; PARADYM RF CRT SonR model 9770
PARADYM ICD and CRT-d with PARAD+ algorithm available

Detailed Description:
The primary endpoint is to demonstrate that 95% of patients implanted with PARAD+ algorithm are free from inapproporiate shock compared to 92.5% in general ICD population.
