"abstract": "In this paper, algorithm estimating the blood pressure\r\nwas proposed using the pulse transit time (PTT) as a more convenient\r\nmethod of measuring the blood pressure. After measuring ECG and\r\npressure pulse, and photoplethysmography, the PTT was calculated\r\nfrom the acquired signals. Thereafter, the system to indirectly measure\r\nthe systolic pressure and the diastolic pressure was composed using\r\nthe statistic method. In comparison between the blood pressure\r\nindirectly measured by proposed algorithm estimating the blood\r\npressure and real blood pressure measured by conventional\r\nsphygmomanometer, the systolic pressure indicates the mean error of\r\n\u00b13.24mmHg and the standard deviation of 2.53mmHg, while the\r\ndiastolic pressure indicates the satisfactory result, that is, the mean\r\nerror of \u00b11.80mmHg and the standard deviation of 1.39mmHg. These\r\nresults are satisfied with the regulation of ANSI\/AAMI for\r\ncertification of sphygmomanometer that real measurement error value\r\nshould be within the mean error of \u00b15mmHg and the standard\r\ndeviation of 8mmHg. These results are suggest the possibility of\r\napplying to portable and long time blood pressure monitoring system\r\nhereafter.",
