Atrial fibrillation (AF) screening after ischemic stroke or transient ischemic attack (TIA) is given high priority in clinical guidelines. However, patient selection, electrocardiogram (ECG) modality and screening duration remains undecided and current recommendations vary. The aim of this study was to investigate the clinical practice of AF screening after ischemic stroke or TIA at Swedish stroke units. In collaboration with the stakeholders of the Swedish Stroke Register (Riksstroke) a digital survey was drafted, then tested and revised by three stroke consultants. The survey consisted of 17 multiple choice/ free text questions and was sent by e-mail to the medical directors at all stroke units in Sweden. All 72 stroke units in Sweden responded to the survey. Most stroke units reported that ≥ 75% of ischemic stroke (69/72 stroke units) or TIA patients (67/72 stroke units), without previously known AF, were screened for AF. Inpatient telemetry ECG was the method of first-choice in 81% of the units, but 7% reported lack of access. A variety of standard monitoring durations were used for inpatient telemetry ECG. The second most common choice was Holter ECG (17%), also with considerable variations in monitoring duration. Other AF screening modalities were used as a first-choice method (handheld and patch ECG) but less frequently. Clinical practice for AF screening after ischemic stroke or TIA differed between Swedish stroke units, both in choice of AF screening methods as well as in monitoring durations. There is an urgent need for evidence and evidence-based recommendations in this field. Not applicable.

瑞典缺血性中风和短暂性脑缺血发作后房颤筛查实践的巨大差异：一项调查研究

临床指南高度重视缺血性中风或短暂性脑缺血发作（TIA）后的心房颤动（AF）筛查。然而，患者选择、心电图 (ECG) 方式和筛查持续时间尚未确定，目前的建议也各不相同。本研究的目的是调查瑞典卒中单位缺血性卒中或 TIA 后 AF 筛查的临床实践。与瑞典中风登记处 (Riksrinkle) 的利益相关者合作，起草了一份数字调查，然后由三名中风顾问进行测试和修订。该调查包括 17 个多项选择/自由文本问题，并通过电子邮件发送给瑞典所有中风病房的医疗主管。瑞典所有 72 个卒中单位均对调查做出了回应。大多数卒中单位报告称，≥ 75% 的缺血性卒中（69/72 卒中单位）或 TIA 患者（67/72 卒中单位）既往不知道 AF，但接受了 AF 筛查。住院遥测心电图是 81% 的单位的首选方法，但 7% 的单位表示无法使用。住院患者遥测心电图采用了多种标准监测持续时间。第二个最常见的选择是动态心电图 (17%)，监测持续时间也有很大差异。其他 AF 筛查方式被用作首选方法（手持式和贴片心电图），但频率较低。瑞典不同卒中单位之间缺血性卒中或 TIA 后 AF 筛查的临床实践在 AF 筛查方法的选择以及监测持续时间方面均有所不同。该领域迫切需要证据和基于证据的建议。不适用。
