The exclusion criteria were: (1) AF on the initial 12-channel ECG (2) a history of paroxysmal or persistent AF (3) AF on 24-h Holter ECG registered during the present hospitalization period and (4) mechanical thrombectomy treatment for AIS. The inclusion criteria for the study group were as follows: (1) AIS patient (2) at least 18 years of age, who was able (3) to use the AliveCor KM ECG monitor (i.e., they were able to record at least one 30-s ECG) and (4) to provide informed consent. Ischemic stroke was diagnosed based on the neurological syndrome and results of head computed tomography examination.

All studied patients signed the offline consent form. The research team discussed the study with the patients, allowed them to read the informed consent, and answered all questions. The study was conducted in the Department of Neurology and Epileptology, Professor Orlowski’s Hospital, Warsaw, Poland. KM detected AF in the selected AIS patients with high specificity and sensitivity.Īpproval for the study by the local Ethics Committee of Centre of Postgraduate Medical Education was obtained before subject enrolment (Prot. (4) Conclusions: the results of this study suggest that it is feasible to use KM device to detect AF in the selected AIS patients (younger and in better neurological condition). Sensitivity and specificity of KM for AF was 100% and 98.3%, respectively.

Cardiologist confirmed the AF in 0.3% AIS patients. KM device detected AF in 2.8% of AIS patients and in 2.2% of ECG records. The withdrawal rate after the start of the intervention was 6%. The withdrawal rate before the start of the intervention was 26%. (3) Results: the recruitment rate among AIS patients was 26.3%. The feasibility was evaluated using operationalization criteria. Each KM ECG record was verified by a cardiologist. Thirty-second single-lead electrocardiogram (ECG) usages were recorded on demand for three days using KM portable device. (2) Methods: the AIS patients were recruited to the study. The aim of the study was to define the group of acute ischemic stroke (AIS) patients who can use the KM device and assess the diagnostic test accuracy. (1) Background: AliveCor KardiaMobile (KM) is a portable electrocardiography recorder for detection of atrial fibrillation (AF).
