The Syncardia™ total artificial heart (TAH) is an option for patients as a bridge to transplant in those who are not candidates for left ventricular assist devices (LVAD) due to right ventricular failure. Postoperative course is highly dependent on volume status and aggressive diuresis is often necessary. One complication from aggressive diuresis is hypokalemia; however, in these patients we tolerate a lower potassium level because cardiac arrhythmias are not a concern. However, in two separate instances non-cardiac symptoms related to severe hypokalemia occurred. These symptoms included nystagmus in one patient and agitation, tremors, and having an "out-of-body" experience in the other patient. Both these patients had resolution of symptoms with potassium replacement.
Syncardia™ 全人工心脏（TAH）是那些因右心室衰竭而不适合使用左心室辅助装置（LVAD）的患者作为移植桥梁的一种选择。术后病程高度依赖于容量状态，积极利尿通常是必要的。积极利尿的一个并发症是低钾血症；然而，在这些患者中，我们可以耐受较低的钾水平，因为心律失常不是问题。 然而，在两个不同的病例中，出现了与严重低钾血症相关的非心脏症状。这些症状包括一名患者出现眼球震颤，另一名患者出现躁动、震颤和 “灵魂出窍” 的体验。这两名患者在补充钾后症状均得到缓解。
