A Prospective Study on Clinical Profile and the Utility of 72-h Holter Monitoring in Acute Ischaemic Stroke and Transient Ischaemic Attack (TIA) Patients

72-hour Holter monitoring demonstrated high clinical utility in detecting AF and other clinically significant arrhythmias in acute ischaemic stroke and TIA patients, with direct therapeutic impact through timely initiation of anticoagulation. Importantly, the identification of SVT in 12.5% of patients, particularly those with a higher arrhythmic burden, highlights a potential preclinical substrate of atrial cardiopathy that may precede overt AF. These findings support the incorporation of extended Holter monitoring into post-stroke evaluation, especially for high-risk groups, both to optimise etiological classification and to enable personalised secondary prevention strategies that reduce the risk of recurrent cerebrovascular events.
