Original Title: Monitor cardiaco implantable para síncope de causa desconocida
Authors' recomendations: Low-quality evidence suggests that the use of implantable cardiac monitors in patients with recurrent syncope, which could not be diagnosed by standard assessment, might increase the rate of arrhythmic syncope diagnosis in a small percentage of patients. This applies to syncopes resulting from bradyarrhythmia, not detecting syncopes of potential ventricular etiology. Low-quality evidence did not show that the use of these monitors might reduce mortality at long-term, due to the high heterogeneity of the studies published. Clinical practice guidelines from the United States, Europe and Argentina, as well as different health funders, recommend and consider its use, mainly in those patients with recurrent syncope of uncertain etiology, with high-risk criteria (severe coronary artery or structural disease, syncope after effort, family history of sudden death, non-sustained ventricular tachycardia, bifascicular block, pre-excited QRS complexes) highly likely to recur during the study period, or in those at high risk after conducting a comprehensive assessment that could not determine its cause or a specific treatment. This technology is not covered by the Latin American funders and is not included in the Argentina’s Medical Mandatory Program. No economic evaluations of the cost-effectiveness or budget impact of this technology are available in Argentina.
