Heart rate variability (HRV) biofeedback is an emerging treatment for many health conditions involving dysregulation of the autonomic nervous system including hypertension, gastric pain, anxiety, and depression. Hiccups are frequently considered an annoyance. However, when intractable (lasting over 1 month), they can become debilitating, with some patients resorting to invasive treatments that often involve the phrenic nerve. Theoretically, HRV biofeedback should also provide a means to stimulate the phrenic nerve and could be an alternative option. We report the successful treatment of a 5 year-long case of intractable hiccups with one session of HRV biofeedback training. These results suggest that biofeedback may be a useful, non-invasive means of relieving intractable hiccups. No clear causality can be inferred from a single case, and further study is needed to determine if this finding has wider applicability.
心率变异性（HRV）生物反馈是一种新兴的治疗方法，可用于治疗许多涉及自主神经系统失调的健康状况，包括高血压、胃痛、焦虑和抑郁。呃逆通常被认为是一种烦人的现象。然而，当呃逆变得无法控制（持续超过 1 个月）时，它可能会使人衰弱，有些患者会诉诸于侵入性治疗，这些治疗通常涉及膈神经。从理论上讲，HRV 生物反馈也应该提供一种刺激膈神经的方法，并且可能是一种替代选择。我们报告了一例成功治疗长达 5 年的难治性呃逆病例，该病例仅接受了一次 HRV 生物反馈训练。这些结果表明，生物反馈可能是一种有用的、非侵入性的缓解难治性呃逆的方法。由于这只是一个单一病例，不能从中推断出明确的因果关系，因此需要进一步研究以确定这一发现是否具有更广泛的适用性。
