Insertable Cardiac Monitor

Insertable cardiac monitors detected atrial fibrillation much more often than standard of care over three years in the STROKE AF trial. The model assumed high device sensitivity and effectively perfect diagnostic specificity for atrial fibrillation detection. The model assumed an insertable cardiac monitor battery life of 4.5 years, after which detection rates returned to standard-of-care levels. Insertable cardiac monitoring carried modeled risks of explantation and infection. Insertable cardiac monitoring was evaluated as a strategy to detect atrial fibrillation after ischemic stroke attributed to large-artery atherosclerotic disease or small-vessel occlusive disease.
