Head-upright tilt table testing has emerged as an exciting technique for evaluating episodes of autonomically mediated syncope. It may be performed using gravity alone as the provocative stimulus or with the addition of isoproterenol. The classic neurocardiogenic response to the test is a sudden drop in blood pressure followed by a decrease in heart rate, but other abnormal response patterns have also been reported. Continuing investigations will improve understanding of autonomic disturbances that cause orthostatic intolerance and will help elaborate the role of tilt table testing in their evaluation and management.
头高位倾斜试验已成为一种用于评估自主神经介导性晕厥发作的令人兴奋的技术。它可以仅使用重力作为激发刺激来进行，也可以添加异丙肾上腺素。该测试的典型神经心源性反应是血压突然下降，随后心率降低，但也有其他异常反应模式的报道。持续的研究将增进对导致直立不耐受的自主神经紊乱的理解，并有助于阐明倾斜试验在其评估和管理中的作用。
