Everything Hertz: methodological issues in short-term frequency-domain HRV
Frequency analysis of the electrocardiographic RR interval is a common method of quantifying autonomic outflow by measuring the beat-to-beat modulation of the heart (heart rate variability; HRV). This review identifies a series of problems with the methods of doing so-the interpretation of low-frequency spectral power, the multiple use of equivalent normalized low frequency (LFnu), high frequen...
متن کاملShort-term heart rate variability (HRV) in healthy dogs.
Heart rate variability (HRV) is a well established mortality risk factor in both healthy dogs and those with heart failure. While the standards for short-term HRV analysis have been developed in humans, only reference values for HRV parameters determined from 24-hour ECG have been proposed in dogs. The aim of this study was to develop the reference values for short-term HRV parameters in a grou...
متن کاملHeart Rate Variability (HRV) of two short-term photoplethysmogram (PPG)
Heart rate variability (HRV) is often analyzed using short-term studies: 5-min and 2-min heart rate datasets. The correlation between the two data segments in HRV analysis has not been well understood. This paper reports a statistical comparison of the results of HRV spectral analysis for the 5-minute versus 2-minute short-term studies using photoplethysmogram (PPG). Twenty repeat measurements ...
متن کاملBehavioral and Methodological Issues in Motor Short-Term Memory and its Basic Experimental Paradigm
We examined in this study the basic behavioral correlates of motor short-term memory and several methodological issues with respect to the investigative paradigm. We first reviewed pioneering studies on motor short-term memory and then addressed methodological issues including dependent measures, directional biasing effects, and separation of movement cues. Finally, we examined the methodologic...
متن کاملA feasibility study of methodological issues and short-term outcomes in seriously injured older adults.
BACKGROUND For any given traumatic injury, older adults experience a longer hospitalization, more complications, and higher mortality than do younger patients. OBJECTIVES To prospectively identify problems in designing follow-up studies in seriously injured older adults without head injury and to examine outcomes after serious trauma in older adults who were sent to a level I trauma center. ...
