Brief Summary
This is a prospective single-center study that aims to evaluate the effects of non-invasive transcutaneous spinal cord stimulation on systemic and pulmonary hemodynamics, assessed during right heart catheterization in patients with heart failure and persistent or transient hypotension subjected to be included into the heart transplantation waiting list.

Outcome Measures
Primary Outcomes (1)
Systolic blood pressure elevation
It is suggested that spinal cord stimulation will elevate averaged systolic blood pressure by \>5 mmHg within 10 minutes, as compared to tilt testing without stimulation, and as measured invasively through a vascular catheter. Number of participants with increase in systolic blood pressure by more than 5 mmHg within 10 minutes will be counted. The achievement of the primary outcome will be considered if \>50% of patients will have an increase in systolic blood pressure.

Spinal cord stimulation in heart failure patients with hypotension
EXPERIMENTALAdhesive patches are applied to subjects' back skin. Single stimuli are delivered in order to define the stimulation threshold under the guidance of neuromyography. Vascular access is performed (jugular or subclavian) according to conventional preparation to right heart catheterization. Invasive hemodynamic measures are performed as usual. High-frequency spinal cord stimulation at T5 level is initiated, and repeated hemodynamic measures performed within 2 minutes. Stimulation lasts for 5-10 minutes, and then ceased. Following a 5-minutes waiting period, repeat hemodynamic measures are performed. The same sequence of steps applies for stimulation levels T7-8 and a combination of T5 and T7-8. Then the procedure is completed and data are analysed.
Interventions
High-frequency stimulation with modulated current via skin patches captures posterior horns of the spinal cord and this activation leads to blood pressure elevation.
