A systemic evaluation, including clinical characteristics, electrocardiography, and echocardiography, was performed to estimate the prevalence and prognosis of cardiac injury.

During the hospital stay, 3 out of 74 patients had a prolonged rate-corrected QT interval (457, 468, and 461 milliseconds), and one patient developed supraventricular tachycardia. Eight (10.8%) patients developed the intermediate syndrome, and six (8.1%) died. None of the hemodynamic or electrocardiographic abnormalities was associated with in-hospital mortality or intermediate syndrome development on univariant analysis. Baseline echocardiography at hospital discharge was performed in 27 patients (admitted during 2018) and normal in all except mild tricuspid regurgitation in one. At a 6-month follow-up, 23 cases were available for cardiovascular screening (including echocardiography) and had a normal evaluation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Cardiac toxicity is uncommon after acute OP self-ingestion and lacks prognostic significance.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1093\/toxres\/tfab036","type":"journal-article","created":{"date-parts":[[2021,3,26]],"date-time":"2021-03-26T16:09:53Z","timestamp":1616774993000},"page":"446-452","source":"Crossref","is-referenced-by-count":27,"title":["Cardiac injury in organophosphate poisoning after acute ingestion"],"prefix":"10.1093","volume":"10","author":[{"given":"Ashok Kumar","family":"Pannu","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, 4th Floor, F Block, Nehru Hospital, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashish","family":"Bhalla","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, 4th Floor, F Block, Nehru Hospital, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R I","family":"Vishnu","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, 4th Floor, F Block, Nehru Hospital, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sahil","family":"Garg","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, 4th Floor, F Block, Nehru Hospital, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deba Prasad","family":"Dhibar","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, 4th Floor, F Block, Nehru Hospital, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Navneet","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Postgraduate Institute of Medical Education and Research, 4th Floor, F Block, Nehru Hospital, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajesh","family":"Vijayvergiya","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Postgraduate Institute of Medical Education and Research, 3rd Floor, Block - C, Advanced Cardiac Center, PGIMER, Chandigarh 160012, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,4,26]]},"reference":[{"key":"2021070810591240400_ref1","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1186\/1471-2458-7-357","article-title":"The global distribution of fatal pesticide self-poisoning: systematic review","volume":"7","author":"Gunnell","year":"2007","journal-title":"BMC Public Health"},{"key":"2021070810591240400_ref2","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1179\/oeh.2002.8.3.243","article-title":"Surveillance of pesticide related illness in the developing world: putting the data to work","volume":"8","author":"Murray","year":"2002","journal-title":"Int J Occup Environ Health"},{"key":"2021070810591240400_ref3","doi-asserted-by":"crossref","first-page":"808","DOI":"10.1177\/096032719501401005","article-title":"Mortality due to poisoning in a developing agricultural country.
