Comparing the Memory Effects of 50-Hz Low-Frequency and 10-kHz High-Frequency Thoracic Spinal Cord Stimulation on Spinal Neural Network in a Myocardial Infarction Porcine Model.

Objective: This study evaluated the effects of cessation of both conventional low-frequency (50 Hz) and high-frequency (10 kHz) spinal cord stimulation (SCS) on the cardiospinal neural network activity in pigs with myocardial infarction (MI). The objective is to provide an insight into the memory effect of SCS.

Materials And Methods: In nine Yorkshire pigs, chronic MI was created by delivering microspheres to the left circumflex coronary artery.
