SVT with aberrancy, preexcitation, paced rhythm, rate-dependent bundle branch block, preexisting conduction defects or SVT due to drugs, and electrolyte abnormality can also be wide complex. Wide-complex tachycardia (WCT) is often ventricular tachycardia (VT), but fascicular VT (fVT) can present as NCT. Thus, WCT can be either VT or SVT. This has been a perplexing problem for the emergency physician for ages. Here, in this case series, we describe the novel use of point-of-care ultrasound to differentiate SVT from VT.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/2452-2473.357346","type":"journal-article","created":{"date-parts":[[2022,9,29]],"date-time":"2022-09-29T14:29:35Z","timestamp":1664461775000},"page":"221-225","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Tachycardia origin prediction using point of care ultrasound (TOP-UP) - A novel technique"],"prefix":"10.4103","volume":"22","author":[{"given":"Sasikumar","family":"Mahalingam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunaseelan","family":"Rajendran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Balamurugan","family":"Nathan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manu","family":"Ayyan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivekanandan Muthu","family":"Pillai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-8-20240909","doi-asserted-by":"crossref","first-page":"23","DOI":"10.15420\/aer.2013.2.1.23","article-title":"Wide complex tachycardia \u2013 Ventricular tachycardia or not ventricular tachycardia, that remains the question","volume":"2","author":"Garner","year":"2013","journal-title":"Arrhythm Electrophysiol Rev"},{"key":"R2-8-20240909","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1016\/j.repc.2013.07.016","article-title":"The value of electrocardiography for differential diagnosis in wide QRS complex tachycardia","volume":"33","author":"Sousa","year":"2014","journal-title":"Rev Port Cardiol"},{"key":"R3-8-20240909","first-page":"e1423","article-title":"Narrow complex ventricular tachycardia","volume":"9","author":"Sundhu","year":"2017","journal-title":"Cureus"},{"key":"R4-8-20240909","doi-asserted-by":"crossref","first-page":"465","DOI":"10.1093\/europace\/euq430","article-title":"Diagnostic criteria of broad QRS complex tachycardia: Decades of evolution","volume":"13","author":"Alzand","year":"2011","journal-title":"Europace"},{"key":"R5-8-20240909","doi-asserted-by":"crossref","first-page":"48","DOI":"10.15420\/usc.2007.4.1.48","article-title":"Wide complex tachycardias \u2013 The differential diagnosis remains wide and complex","volume":"4","author":"Miller","year":"2007","journal-title":"US Cardiol"},{"key":"R6-8-20240909","doi-asserted-by":"crossref","first-page":"354","DOI":"10.1016\/j.recesp.2015.11.024","article-title":"Echocardiographic diagnosis of ventricular tachycardia: Is there a problem with clinical and electrocardiographic diagnostic criteria?
