To cite the VU-AMS device and DAMS program you could use the first two journal publications describing the VU-AMS 4.6 device:
- De Geus, E. J., Willemsen, G. H., Klaver, C. H., & van Doornen, L. J. (1995). Ambulatory measurement of respiratory sinus arrhythmia and respiration rate. Biological psychology, 41(3), 205-227.
- Willemsen, G. H., DeGeus, E. J., Klaver, C. H., VanDoornen, L. J., & Carrofl, D. (1996). Ambulatory monitoring of the impedance cardiogram. Psychophysiology, 33(2), 184-193.
Or you may specifically reference papers that have a detailed description of heart rate and heart rate variability (HR, RMSSD, RSA) assessment or systolic time intervals and stroke volume assessments (PEP, LVET, SV).
HR, RMSSD, RSA:
- De Geus, E. J., Willemsen, G. H., Klaver, C. H., & van Doornen, L. J. (1995). Ambulatory measurement of respiratory sinus arrhythmia and respiration rate. Biological psychology, 41(3), 205-227.
- Goedhart, A. D., Van Der Sluis, S., Houtveen, J. H., Willemsen, G., & De Geus, E. J. (2007). Comparison of time and frequency domain measures of RSA in ambulatory recordings. Psychophysiology, 44(2), 203-215.
PEP, LVET, SV:
- Willemsen, G. H., DeGeus, E. J., Klaver, C. H., VanDoornen, L. J., & Carrofl, D. (1996). Ambulatory monitoring of the impedance cardiogram. Psychophysiology, 33(2), 184-193.
- Riese, H., Groot, P. F., van den Berg, M., Kupper, N. H., Magnee, E. H., Rohaan, E. J., … & de Geus, E. J. (2003). Large-scale ensemble averaging of ambulatory impedance cardiograms. Behavior Research Methods, Instruments, & Computers, 35(3), 467-477.
- Goedhart, A. D., Kupper, N., Willemsen, G., Boomsma, D. I., & de Geus, E. J. (2006). Temporal stability of ambulatory stroke volume and cardiac output measured by impedance cardiography. Biological Psychology, 72(1), 110-117.
A single publication that deals with ambulatory recording of both RSA and PEP and explains 24-hour recording labeling is:
- De Geus, E. J., & Van Doornen, L. J. (1996). Ambulatory assessment of parasympathetic/sympathetic balance by impedance cardiography. Ambulatory assessment: Computer-assisted psychological and psychophysiological methods in monitoring and field studies, 141-163.
