Sleep Apnea Monitoring - SAM™

Proactive management of comorbidities. Early detection, long-term risk reduction. 1–6

Healthcare Professionals Cardiac Rhythm Management Sleep Apnea Monitoring

Sleep apnea + cardiovascular comorbidities

= a dangerous combination

Severe sleep apnea is strongly associated with and has a negative impact on cardiovascular comorbidities:

  • 58% higher risk of heart failure2
  • Risk of atrial fibrillation is 4-times higher3
  • More Resistance to pharmacological treatment4
  • More recurrence of atrial fibrillation after ablation or cardioversion5,6

Sleep apnea is highly prevalent, yet underdiagnosed.7–9

  • Severe Sleep Apnea burden (RDI >20) was identified in 31.1 % of patients of an unselected pacemaker population9
  • 50-90% of patients are undiagnosed and therefore, untreated8

Protect patients with SAM

SAM is a unique Sleep Apnea Monitoring tool which has been validated against the gold standard Apnea Hypopnea Index determined by polysomnography.1

A reliable screening tool, SAM has a high specificity of 85% and a high sensitivity of 89%.

Quick and efficient follow-up

SAM detects and reports severe sleep apnea allowing for quick and efficient follow-up to manage this dangerous disorder.1
