The WashU School of Medicine Heart Rate Variability Laboratory provides expertise is all aspects of heart rate variability data collection, study design, analysis and interpretation of results. Heart rate variability analysis provides insights in to the functioning of the autonomic nervous system and has proven utility in risk stratitication in different populations and 24-hour or longer recordings can provide information about sleep and sleep disorders. Heart rate variability can be assessed from any continuous ECG recordings in human or animals including Holter recordings, polysomnograms and ICU monitors. Provides validation for heart rate recordings from commercial self-monitoring devices. The lab provides technical support for data collection, Holter scanning, calculation of multiple measures of heart rate variability, graphical analysis and assistance with data analysis, grant writing and manuscript preparation. Large datasets of scanned Holter recordings, digitized Holter ECGs, polysomnograms and scanned polysomnogram ECGs are also available for novel collaborative applications. The lab also provides training opportunities for volunteer research assistants, including non-resident medical students, work study students, participants in the STARS program for high school student and WashU students doing a research thesis. Intensive and supervised training in HRV methods is also available on a paid basis. Currently all activities are virtual , including trainings, but data collection for ongoing human studies is accomplished by providing a small MyPatch Holter recorder to subjects and instructing them on how to hook themselves up. The recorder can store up to 5 days of continuous ECGs on 3 channels. Patients remove the recorder and return it via overnight delivery and the signal is uploaded to Box where it can be accessed for analysis.
