A Case-Based Classification of Respiratory Sinus Arrhythmia
نویسندگان
چکیده
Respiratory Sinus Arrhythmia has until now been analysed manually by reviewing long time series of heart rate measurements. Patterns are identified in the analysis of the measurements. We propose a design for a classification system of Respiratory Sinus Arrhythmia by time series analysis of heart and respiration measurements. The classification uses Case-Based Reasoning and Rule-Based Reasoning in a Multi-Modal architecture. The system is in use as a research tool in psychophysiological medicine, and will be available as a decision support system for treatment personnel.

Building a Case-Base for Stress Diagnosis: An Analysis of Classified Respiratory Sinus Arrhythmia Sequences
Building upon previous work on pattern classification of Respiratory Sinus Arrhythmia (RSA) used in stress disorder treatments, this paper presents an extended approach to analyze the implications of sequences of classified RSA. Through a combination of consulting with field experts and clustering of RSA sequences, each coupled to a particular patient session, session stereotype cases are creat...
متن کاملA case of respiratory sinus arrhythmia and vasovagal attacks: use of cosinor analysis for diagnosis and for monitoring treatment.
An 18 year old girl presented with frequent vasovagal attacks and sinus arrhythmia. The amplitude of respiratory sinus arrhythmia assessed by cosinor analysis was 20%; the predicted value for a normal girl of this age is 4% and the 95% confidence interval is 0-8%. Treatment with propantheline, in a dose sufficient to reduce the amplitude of sinus arrhythmia to normal, abolished her symptoms.
متن کاملA Case-Based Approach for Classification of Physiological Time-Series
Complex measurement classification is often difficult, as in the medical domain, and it usually takes a long time to fully master all aspects involved. An automated measurement classification system would ease the diagnostic process for treatment personnel, especially for less experienced clinicians. This thesis contains results from research in the field of Artificial Intelligence (AI) applied...
متن کاملRespiratory sinus arrhythmia in freely moving and anesthetized rats.
Heart rate increases during inspiration and slows during postinspiration; this respiratory sinus arrhythmia helps match pulmonary blood flow to lung inflation and maintain an appropriate diffusion gradient of oxygen in the lungs. This cardiorespiratory pattern is found in neonatal and adult humans, baboons, dogs, rabbits, and seals. Respiratory sinus arrhythmia occurs mainly due to inhibition o...
متن کاملDoes respiratory sinus arrhythmia serve a buffering role for diastolic pressure fluctuations?
Though many consider the magnitude of respiratory sinus arrhythmia as an index of cardiac vagal control, its physiological origins remain unclear. One influential model postulates that the systolic pressure rise within a given beat stimulates the baroreflex arc to adjust the following heart period such that diastolic pressure is "stabilized" and hence displays lesser fluctuation. Accordingly, t...
