Surge BP is effectively evaluated by our new BP monitoring device. To the best of our knowledge, we are the first to develop an algorithm for the automatic detection of surge BP from continuous \u201cbeat-by-beat\u201d (BbB) BP measurements. It enables clinicians to save significant time identifying surge BP in big data from their patients\u2019 continuous BbB BP measurements. A total of 94 subjects (74 males and 20 females) participated in our study to develop the surge BP detection algorithm, resulting in a total of 3272 surges collected from the study subjects. The surge BP detection algorithm is a simple classification model based on supervised learning which formulates shape of surge BP as detection rules. Surge BP identified with our algorithm was evaluated against surge BP manually labeled by experts with 5-fold cross validation. The recall and precision of the algorithm were 0.90 and 0.64, respectively. Processing time on each subject was 11.0\u2009\u00b1\u20094.7\u00a0s. Our algorithm is adequate for use in clinical practice and will be helpful in efforts to better understand this unique aspect of the onset of CVD.<\/jats:p>","DOI":"10.1007\/s11517-020-02162-4","type":"journal-article","created":{"date-parts":[[2020,4,13]],"date-time":"2020-04-13T03:15:20Z","timestamp":1586747720000},"page":"1393-1404","update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Automatic detection algorithm for establishing standard to identify \u201csurge blood pressure\u201d"],"prefix":"10.1007","volume":"58","author":[{"given":"Ayako","family":"Kokubo","sequence":"first","affiliation":[]},{"given":"Mitsuo","family":"Kuwabara","sequence":"additional","affiliation":[]},{"given":"Hiroshi","family":"Nakajima","sequence":"additional","affiliation":[]},{"given":"Naoko","family":"Tomitani","sequence":"additional","affiliation":[]},{"given":"Shingo","family":"Yamashita","sequence":"additional","affiliation":[]},{"given":"Toshikazu","family":"Shiga","sequence":"additional","affiliation":[]},{"given":"Kazuomi","family":"Kario","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2020,4,13]]},"reference":[{"issue":"3","key":"2162_CR1","doi-asserted-by":"publisher","first-page":"262","DOI":"10.1016\/j.pcad.2016.04.001","volume":"59","author":"K Kario","year":"2016","unstructured":"Kario K (2016) Evidence and perspectives on the 24-hour management of hypertension: hemodynamic biomarker-initiated \u2018anticipation medicine\u2019 for zero cardiovascular event.
