1.6.5.2.2 Study Objectives
This clinical investigation was designed to collect information on
the performance and function of the Deikos A+/Kainox VDD ICD
system. The specific predefined objectives of the investigation
included the rate of inappropriate, i.e. unnecessary deliveries of
antitachycardia therapy due to supraventricular tachycardia
(SVT), the tachyarrhythmia conversion efficacy of the system with
activated SMART Detection™ algorithm, the rate of appropriate
atrial sensing and the morbidity rate.
1.6.5.2.3 Results
The mean implant
duration was 8.9 ± 4.4 months with a
cumulative implant duration of 732 months. No unanticipated
adverse events were reported during the study. There were two
deaths reported, which were unrelated to the implanted device. A
summary of the results obtained during the evaluation is provided
in Table 25
.

The investigator determined the appropriateness of atrial sensing. The rate is
determined by the number of appropriate atrial sensing evaluations divided by the
total number of evaluations.
2
Conversion data were collected in the clinical study for both induced and
spontaneous ventricular tachyarrhythmia episodes. Therefore, both types of
tachyarrhythmia episodes were included in the analysis.
