Arrhythmias occurred in 65.3% of patients, most commonly ventricular tachycardia (21.8%). Multivariable logistic regression identified higher Killip class (III\u2013IV) and prolonged T wave peak\u2013T wave end interval as the independent predictors of arrhythmias. A T wave peak\u2013T wave end cutoff \u226598\u2009ms showed a sensitivity of 77.3%, specificity of 52.9%, and diagnostic accuracy of 69%. The T wave peak\u2013T wave end and T wave peak\u2013T wave end\/QT ratios were significantly higher among nonsurvivors, along with greater clinical severity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A prolonged baseline T wave peak\u2013T wave end interval (\u226598\u2009ms) and higher Killip class independently predict early arrhythmias in acute myocardial infarction.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/03000605261452586","type":"journal-article","created":{"date-parts":[[2026,6,11]],"date-time":"2026-06-11T02:43:28Z","timestamp":1781145808000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Predictive utility of the baseline Tp\u2013e interval for early arrhythmic events in acute myocardial infarction: A cohort study"],"prefix":"10.1177","volume":"54","author":[{"given":"Sreeja","family":"Gandamsetty","sequence":"first","affiliation":[{"name":"Manipal Academy of Higher Education"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2377-2772","authenticated-orcid":false,"given":"Shashikala","family":"Taggarshe Surkunda","sequence":"additional","affiliation":[{"name":"Manipal Academy of Higher Education"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anupa Appu","family":"Shetty","sequence":"additional","affiliation":[{"name":"Manipal Academy of Higher Education"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Divya D","family":"Pai","sequence":"additional","affiliation":[{"name":"Manipal Academy of Higher Education"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8392-2366","authenticated-orcid":false,"given":"Souvik","family":"Chaudhuri","sequence":"additional","affiliation":[{"name":"Kasturba Medical College, Manipal Academy of Higher Education"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barkur Ananthakrishna","family":"Shastry","sequence":"additional","affiliation":[{"name":"Manipal Academy of Higher Education"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"e_1_3_10_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12872-025-05022-x"},{"key":"e_1_3_10_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12872-017-0482-9"},{"key":"e_1_3_10_4_2","doi-asserted-by":"publisher","DOI":"10.59249\/LSWK8578"},{"key":"e_1_3_10_5_2","doi-asserted-by":"publisher","DOI":"10.4103\/0972-5229.158271"},{"key":"e_1_3_10_6_2","doi-asserted-by":"publisher","DOI":"10.2459\/JCM.0000000000000015"},{"key":"e_1_3_10_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccep.2021.04.010"},{"key":"e_1_3_10_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/jce.13453"},{"key":"e_1_3_10_9_2","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2024.1342761"},{"key":"e_1_3_10_10_2","doi-asserted-by":"publisher","DOI":"10.15420\/aer.2017.24.1"},{"key":"e_1_3_10_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.122.011677"},{"key":"e_1_3_10_12_2","doi-asserted-by":"publisher","DOI":"10.1093\/europace\/eux104"},{"key":"e_1_3_10_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2017.05.031"},{"key":"e_1_3_10_14_2","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2022.869168"},{"key":"e_1_3_10_15_2","doi-asserted-by":"publisher","DOI":"10.1155\/2024\/4904508"},{"key":"e_1_3_10_16_2","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-147-8-200710160-00010"},{"key":"e_1_3_10_17_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2018.08.1038"},{"key":"e_1_3_10_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(67)90023-9"},{"key":"e_1_3_10_19_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-025-11353-8"},{"key":"e_1_3_10_20_2","doi-asserted-by":"publisher","DOI":"10.1253\/circrep.CR-19-0081"},{"key":"e_1_3_10_21_2","first-page":"e71564","article-title":"Incidence and prognostic significance of arrhythmia in acute myocardial infarction presentation: an observational study","volume":"16","author":"Kurmi P","year":"2024","unstructured":"Kurmi P, Patidar A, Patidar S, et\u00a0al.
