In some cases, such tools are implemented in mobile devices and applied to \u201cmobile learning\u201d (m-learning) activities. In the present work, we show a mobile device tool that emulates the beating heart according to ECG data. The tool has been implemented using skeletal subspace deformation to control the movement of a 3D heart model in real time. It is possible to manipulate the heart model and visualize its inner anatomy. The results of the simulation show that the tool allows online adjustments on the virtual heart according to actual ECG data set by the user or by ECG data files (normal rhythm or arrhythmias). The comparison between clinical data and the results of the simulation validated the cardiac beating simulation. The user experience was evaluated by students of biomedical engineering using a Likert scale. The students evaluated their experience with the tool positively. The results, as a whole, show that the tool may represent a newly accessible resource to help support m-learning in the context of interpreting ECG data. Also, the tool seems to be applicable in a teaching\/learning environment where undergraduates are studying either the ECG or the cardiac anatomy or function.<\/jats:p>","DOI":"10.1177\/0037549717733038","type":"journal-article","created":{"date-parts":[[2017,10,23]],"date-time":"2017-10-23T13:54:52Z","timestamp":1508766892000},"page":"465-476","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["A mobile device tool to assist the ECG interpretation based on a realistic 3D virtual heart simulation"],"prefix":"10.1177","volume":"94","author":[{"given":"Regina C\u00e9lia","family":"Coelho","sequence":"first","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nayara Consuelo Gomes","family":"Rangel Louren\u00e7o","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos Marcelo Gurj\u00e3o","family":"de Godoy","sequence":"additional","affiliation":[{"name":"Universidade Federal de S\u00e3o Paulo, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2017,10,23]]},"reference":[{"key":"bibr1-0037549717733038","doi-asserted-by":"publisher","DOI":"10.4103\/2349-4220.159113"},{"issue":"5","key":"bibr2-0037549717733038","first-page":"356","volume":"39","author":"Ventola CL","year":"2014","journal-title":"P&T"},{"key":"bibr3-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1136\/archdischild-2014-306620"},{"key":"bibr4-0037549717733038","doi-asserted-by":"publisher","DOI":"10.3928\/01484834-20151214-14"},{"key":"bibr5-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1109\/TLT.2009.38"},{"key":"bibr6-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1016\/j.nedt.2014.12.002"},{"key":"bibr7-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1007\/s10916-013-9949-0"},{"key":"bibr8-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2015.03.021"},{"key":"bibr9-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/727401."},{"key":"bibr10-0037549717733038","doi-asserted-by":"publisher","DOI":"10.2147\/AMEP.S75316"},{"key":"bibr11-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCRESAHA.110.223610"},{"key":"bibr12-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1186\/s12938-015-0033-5"},{"key":"bibr13-0037549717733038","volume-title":"The construction of a volumetric cardiac model for real-time ECG simulation","author":"Mooney R","year":"2003"},{"key":"bibr14-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1002\/cav.39"},{"key":"bibr15-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1080\/10255842.2013.795556"},{"key":"bibr16-0037549717733038","first-page":"127","volume-title":"Visions of the future: chemistry and life science","author":"Kohl P","year":"2001"},{"key":"bibr17-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1016\/j.euromechsol.2014.04.001"},{"key":"bibr18-0037549717733038","unstructured":"Heartworks. www.inventivemedical.com (accessed June 14, 2016)."},{"key":"bibr19-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1109\/TMI.2006.872746"},{"issue":"2","key":"bibr20-0037549717733038","first-page":"73","volume":"9","author":"Takahashi K","year":"2007","journal-title":"J Bioelectromagnet"},{"key":"bibr21-0037549717733038","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-01932-6_41"},{"key":"bibr22-0037549717733038","volume-title":"4th INTUITION workshop & conference on virtual reality and virtual environments","author":"Hurmusiadis V.
