SEEQ & LINQ, frequent vs infrequent symptoms

The Syncope Challenge

  • Syncope accounts for 3-5% of ED visits and 1-3% of all hospital admissions1,2
  • Cardiac syncope carries a 6-month mortality rate of greater than 10%, and doubles the risk of death1
  • Syncope negatively impacts patient quality of life3,4
  • Diagnosing patients with infrequent symptoms using a conventional Holter monitor is unlikely, due to low symptom-ECG correlation1

Syncope's Impact on Quality of Life3,4


Survival Rates With and Without Syncope1


Unexplained Syncope Patient Selection Considerations

For syncope patients, the fainting frequency and severity of events should be considered when deciding between short-term monitoring with SEEQ MCT and long-term monitoring with Reveal LINQ ICM.
