Early identification of cardiogenic vertigo (CV) is necessary to prevent serious complications of cardiovascular diseases. However, the literature is limited to case reports without detailed clinical features or diagnostic criteria. The aim of this study was to define characteristics of CV and propose diagnostic criteria. This study included patients with CV diagnosed at Pusan National University and Keimyung University Hospitals. Demographic, clinical, laboratory, and treatment data were analyzed. Of 72 patients with clinically suspicious CV, 27 were finally included. The age ranged from 63 to 88 years (75.1 ± 7.2 years). Recurrent vertigo occurred without syncopal attacks in 52% [95% CI, 32–71], while it preceded (37% [19–58]) or followed (11% [2–29]) syncope. The patients with recurrent isolated vertigo had suffered from symptoms from 15 days to 5 years until final diagnosis (median 122 days). The vertigo lasted only for a few seconds (93% [76–99]) or a few minutes (7% [1–24]). Fourteen patients presented with spinning vertigo, and one of them showed spontaneous downbeat nystagmus during the attack. Accompanying symptoms including chest discomfort, palpitation, headache, arm twitching, and lightheadedness were found in 70% [50–86]. Between patients with and without syncope, there was no difference in clinical parameters and results of cardiac function tests. The most common cardiac abnormality during the attacks of vertigo was bradyarrhythmia (89% [71–98]). Cardiovascular diseases can develop recurrent isolated vertigo without or preceding syncope. Onset age, duration of vertigo, accompanying symptoms, and underlying cardiac diseases can aid in differentiation from other vestibular disorders. Early identification of CV would reduce morbidity and mortality associated with cardiac syncope.

早期识别心源性眩晕（CV）对于预防心血管疾病的严重并发症是必要的。但是，文献仅限于没有详细临床特征或诊断标准的病例报告。这项研究的目的是定义简历的特征并提出诊断标准。这项研究包括釜山国立大学和庆明大学医院诊断为CV的患者。人口统计学，临床，实验室和治疗数据进行了分析。在72位临床可疑的CV患者中，最终纳入了27位。年龄范围为63至88岁（75.1±7.2岁）。复发性眩晕在没有晕厥发作的情况下发生率为52％[95％CI，32-71]，而在晕厥发生之前（37％[19-58]）或之后（11％[2–29]）。复发性孤立性眩晕患者的症状持续15天至5年，直至最终诊断（中位122天）。眩晕仅持续几秒钟（93％[76–99]）或几分钟（7％[1-24]）。14名患者表现为旋转性眩晕，其中1名患者在发作期间表现出自发性的眼震震颤。70％的人出现伴随症状，包括胸部不适，心慌，头痛，手臂抽搐和头昏眼花[50-86]。在有和没有晕厥的患者之间，临床参数和心功能检查结果没有差异。眩晕发作期间最常见的心脏异常是心律失常（89％[71–98]）。心血管疾病可导致反复发作的孤立性眩晕，而无晕厥。发病年龄，眩晕持续时间，伴随症状，以及潜在的心脏病可以帮助区别于其他前庭疾病。尽早发现CV可降低心脏晕厥的发病率和死亡率。
