The hypothesis is that transcutaneous spinal cord stimulation at thoracic level may correct hypotensive episodes during tilt testing in subjects with blood pressure drops.~Eligible patients will sign an informed consent form before the procedure. Non-invasive transcutaneous electrical stimulation of the spinal cord will be applied using modulated electrical impulses through external adhesive electrode patches connected to a neural stimulator device. The study protocol includes analysis of the following parameters: heart rate; 12-lead electrocardiogram; continuous beat-to-beat blood pressure recordings (measured noninvasively by plethysmography) before stimulation, during stimulation and after spinal cord stimulation. All registered data will be analyzed at the end of the procedure.
This is a prospective single-center randomized crossover control study that aims to evaluate the effects of non-invasive transcutaneous spinal cord stimulation in patients with known or suspected orthostatic hypotension.
