Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The incidence of patient intolerance to CLS (referring to the discontinuation of CLS due to worsening subjective symptoms such as dyspnea, palpitations, fatigue, or discomfort) occurring from the activation of the CLS function until the end of the observation period (Day 180). | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) The incidence and changes in subjective symptoms (dyspnea, palpitations, fatigue, and discomfort) from the activation of the CLS function until the end of the observation period (Day 180), compared to pre-implantation. 2) The total duration and longest duration of atrial high rate episode (AHRE) occurring from the activation of the CLS function until the end of the observation period (Day 180). | — |
