Summary: A new case study highlights the potential of Huxley Medical’s SANSA home monitoring platform to detect previously unrecognized sleep apnea and cardiac arrhythmias simultaneously, suggesting it could streamline diagnostics and enhance collaboration between sleep and cardiovascular specialties.
Key Takeaways:
- The SANSA platform can simultaneously assess sleep apnea, arrhythmias, and activity patterns in a single session.
- SANSA identified sleep apnea during daytime naps as well as overnight, revealing limitations of traditional overnight-only HSTs.
- Researchers emphasized SANSA’s potential to unify diagnostic workflows across cardiology, electrophysiology, and sleep medicine, reducing siloed care.
A recently published case study unveils promising investigational data from Huxley Medical’s SANSA home sleep test and monitoring platform, as well as its potential applications.
Published in the abstract book of the 2025 Heart Rhythm Society meeting, the observational study of a 67-year-old man evaluated the feasibility of SANSA to simultaneously assess sleep apnea, arrhythmia, and activity patterns for 24 hours.
The study highlights the high burden of unrecognized sleep apnea in electrophysiology populations and the breadth of insights the SANSA multi-sensing platform can generate from a single use. With continued development, researchers believe SANSA could simplify diagnostic workflows for complex patients and enhance cross-specialty collaboration between cardiology, electrophysiology, and sleep medicine.
Key findings from the SANSA case study include:
- Previously unrecognized sleep apnea was detected in 67% (20/30) of electrophysiology patients being monitored for arrhythmias.
- SANSA revealed sleep apnea during a daytime nap as well as overnight sleep, highlighting how typical overnight-only home sleep apnea testing may miss the full burden of disease and not capture valuable information about patients’ circadian sleep patterns.
- Simultaneous collection of ECG alongside oximetry, motion, and respiration provided valuable context to understand relationships between arrhythmia burden, sleep, and activity level.
The research team suggested that unifying the assessment of sleep-disordered breathing and cardiac arrhythmias could provide valuable insight into disease states and inform clinical management of complex patients.
Co-investigator Rohit Mehta, MD, FACC, FHRS, a cardiac electrophysiologist at the Sanger Heart and Vascular Institute and a professor of Medicine at Wake Forest University School of Medicine, says in a release, “A key unmet need in current diagnostic assessments is the ability to contextualize when disease occurs and to identify how different disease states influence one another. This is particularly true for frequently comorbid conditions like various arrhythmias and sleep apnea. A unified assessment could help tailor disease management for the patient and allow more specific and appropriate therapies to be provided. This study suggests promising potential for SANSA to help address this need and motivates continued clinical research and validation.”
Co-investigator Samuel Sears, PhD, ABPP, a professor of cardiovascular sciences and psychology at East Carolina University and division chief of innovation and research for the East Carolina Heart Institute, says in a release, “Keeping patients active and understanding how their heart responds to physical activity is one of the most critical things we can do for our cardiac patients. Devices like SANSA that provide this level of information alongside standard Holter data could become the standard.”
Researchers also highlighted the promise of SANSA to streamline workflows and strengthen how different clinical specialties work together to provide care. Co-investigator Douglas Kirsch, MD, FAAN, FAASM, medical director of Sleep Medicine at Atrium Health and a clinical professor of Neurology at Wake Forest University School of Medicine, says in a release, “Siloed workflows create complexity for patients and hamper inter-specialty collaboration. Devices with muti-diagnostic capabilities, like SANSA, may enable faster and more efficient approaches to patients where both sleep and cardiac disorders are suspected.”
