WebJan 21, 2024 · Abstract. Diverse electrophysiological studies, including evoked potential, electromyography, and nerve conduction studies, are currently used in the operating room to spare the function of the spinal cord during surgery. Here, we dealt with the basic principles, advantages, and limitations of each electrophysiological study. WebHF-1b, an SP1-related transcription factor, is preferentially expressed in the cardiac conduction system and ventricular myocytes in the heart. Mice deficient for HF-1b survive to term and exhibit normal cardiac structure and function but display sudden cardiac death and a complete penetrance of conduction system defects, including spontaneous …
