Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Determine whether pacing is safe and feasible and demonstrate symptom reduction by measuring data from classic cardiologic exams (HRV on Holter-Ecg, Echocardiogram, Pulmonary Function Test) and measurement of quality of life (Minnesota scale ) and functional class (NYHA) and 6-minute walk test in Heart Failure. Through a comparative study of measurements found before stimulation and measurements found after 4 weeks of stimulation of the vagus-ENV nerve, at the auricular and transcutaneous levels. | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate through a comparative test between the diabetic neuropathy group and the standard intervention group; if there were additional or reduced benefits in terms of symptoms, data from classic cardiologic exams (holter -ecg, echocardiogram and pulmonary function proca), quality of life and functional class in heart failure. | — |
