Exclusion criteria
Exclusion criteria: patients with: - persistent atrial arrhythmias within the past three months; - unstable angina or acure MI within the past 3 months; - already included in another clinical study that could confound the results of this study - pregnancy; - vulnerable subjects as defined in ISO 14155:2011; - unavailability for scheduled follow-up or refusal to cooperate
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint of the study is to investigate any relationship between changes in the SonR1 augmentation and a change in the exercise capacity of CRT patients as assessed by the 6MWTbetween follow-ups | — |
Secondary
| Measure | Time frame |
|---|---|
| - Assess that for 10 out of the 15 first patients enrolled the data stored in the SonR histograms can be used to generate an estimate of the SonR augmentation from rest to exercise; - Observe, qualitatively, whether the changes in the SonR1 augmentation curve can be attributed to other measures of functional exercise capacity or cardiac pathologies; - Investigate the relationship between SonR1 amplitude, heart rate, respiratory rate/amplitude and activity level during patients* daily activities; - Observe, qualitatively, any differences in the change of SonR features with heart rate between the ischemic and non-ischemic patients; - Compare the SonR augmentation calculated from the histogram data and that measured from the raw SonR data; - Assess the quality of the MV signal recorded using different lead reference, in different filtering conditions; - Report all the serious adverse events. | — |
