Abstract
Intravenous metoprolol was found to be significantly more effective than placebo in preventing head-up tilt-table induced neurally mediated syncope. The reproducibility of acute tilt-table testing is only 63% and suggests caution in the interpretation of acute drug testing during tilt-table studies.
摘要
研究发现，静脉注射美托洛尔在预防头高位倾斜试验诱发的神经介导性晕厥方面显著优于安慰剂。急性倾斜试验的可重复性仅为63%，这提示在倾斜试验研究中对急性药物试验结果的解读需谨慎。
