Variability of ACMs of ventricular depolarization between different beats was evaluated in 20 adult men without documented cardiovascular diseases. Comparison of maps using the correlation coefficient showed, that in principle, almost all correlation coefficients were higher than 0.900, that means a high degree of similarity between maps. From our results follows that we can select an ACM from any arbitrary beat for the next evaluation, for example, construction of etalons or comparison with maps of patients with cardiovascular diseases.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130857231","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}

These tests include a local heating of surface tissues, forced occlusion of extremity vessels, forced control of respiration rate using a metronome, breath holding, etc. The original hardware and software measuring complex are worked out. It includes an infrared camera, some other original diagnostic instruments and allows for measurement of the physiological parameters as follows: a) breathing rate, b) temperature of the extremities (both a) and b) are determined using focal plane array-based infrared thermography), c) ECG and heart rate, d) pulse wave velocity in the radial artery, e) core temperature, etc. A diagram illustrating the interconnection of synchronously measured responses of the human's cardiovascular and respiratory systems is presented.

This effectively removes the target tissue directly by breaking the molecular bonds and expunging the decomposed fragments. Excimer lasers in pulse mode emit photons carrying enough energy to break the bonds. To analyze the profile of ablation craters and their depth, a new method using CT imaging was developed and verified. Values of depth determined through this method were compared with values obtained by other methods. The aim of our experiments was to determine the ablation threshold for interaction between excimer laser and different types of tissue. Experimentally obtained values of all measured variables are in accordance with values available in current publications.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116735640","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}
