In four pigs, pressure and volume were simultaneously recorded by using the thin single segment pressure and conductance catheter. Measurements were done under varied cardiac conditions: at baseline, during preload reduction and afterload increase. Volumes were calibrated with intracardiac ultrasound measurements. During preload reduction the pressure and volume decreased as expected. A cautious afterload increase resulted in a corresponding pressure and volume increase, the maximum of the pressure curve changed from early to late. Both SV and EDV increased. The very few arrhythmias were mainly caused by surgical interference. The present study demonstrates that our thin single segment conductance catheter for the simultaneous measurement of LV volume and pressure has a performance that warrants further development with the goal of making the method available for human use. In particular, the catheter did not cause any arrhythmias.","PeriodicalId":386546,"journal":{"name":"2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"58 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123389464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By doing so, one notes that standing still is described by different mechanisms following the frequency. Previous studies exhibit the existence of a control mechanism which stabilizes the upright position at a large enough time scale (from 0.3 s to 1.2 s depending on the method and on the authors) or equivalently at low frequencies. The different mechanisms are separated by a critical time scale or equivalently a critical frequency. This critical frequency is fundamental to understand the control mechanism of upright position: only physiological phenomenon at frequencies larger than this critical frequency could contribute to the task of maintaining equilibrium. A new statistical method is introduced based on recent progress in signal processing: the wavelet analysis. The algorithm is entirely automatic. Seventeen healthy young subjects were studied under quiet-standing conditions, the mean value of critical frequency is 1.8 Hz corresponding to a mean critical time scale 0.68 s. The algorithm is entirely automatic.","PeriodicalId":386546,"journal":{"name":"2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114341118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
