Although SC\u2010VF is traditionally characterized as an idiopathic syndrome occurring in structurally normal hearts, we report the case of a 49\u2010year\u2010old male who experienced sudden cardiac arrest 5\u2009days after successful revascularization for an anterior ST\u2010segment elevation myocardial infarction (STEMI). Despite documented coronary patency, the patient manifested an electrical storm of polymorphic ventricular tachycardia (PMVT) and VF, triggered by ultra\u2010short\u2010coupled premature ventricular contractions (PVCs) (coupling interval\u2009=\u2009240\u2009ms). The arrhythmia proved refractory to conventional lidocaine therapy. However, prompt recognition of the SC\u2010VF phenotype facilitated the cautious administration of verapamil\u2014notwithstanding a mildly reduced left ventricular ejection fraction (LVEF 43%)\u2014which successfully suppressed the rhythmic instability. Following the implantation of an implantable cardioverter\u2010defibrillator (ICD) for secondary prevention, this case suggests that post\u2010AMI inflammatory remodeling is temporally associated with the unmasking of latent electrophysiological vulnerabilities. Ultimately, the detection of an ultra\u2010short coupling interval (&lt;\u2009300\u2009ms) serves as a pivotal clinical marker for transitioning from standard sodium channel blockade to mechanism\u2010driven calcium channel antagonism.<\/jats:p>","DOI":"10.1002\/ccr3.73274","type":"journal-article","created":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T05:23:07Z","timestamp":1786080187000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Case Report of Short\u2010Coupled Ventricular Fibrillation Unmasked During Post\u2010Infarction Inflammatory Remodeling"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1356-313X","authenticated-orcid":false,"given":"ZiYu","family":"Zhao","sequence":"first","affiliation":[{"name":"Department of Cardiovasology Changhai Hospital  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Cardiovasology Changhai Hospital  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Cardiovasology Changhai Hospital  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songhua","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Cardiovasology Changhai Hospital  Shanghai China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/MS9.0000000000001264"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.19102\/icrm.2021.121003"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.12890\/2025_005443"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrcr.2020.11.001"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIR.0000000000001397"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.4103\/jcecho.jcecho_26_19"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.3389\/fcvm.2019.00158"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.eurheartj.a061043"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540\u20108167.1993.tb01236.x"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.cir.89.1.206"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.3390\/cells11071090"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.lanepe.2023.100801"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00399\u2010024\u201000994\u20103"}],"container-title":["Clinical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccr3.73274","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ccr3.73274","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ccr3.73274","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T05:22:07Z","timestamp":1788153727000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ccr3.73274"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,8]]},"references-count":13,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2026,8]]}},"alternative-id":["10.1002\/ccr3.73274"],"URL":"https:\/\/doi.org\/10.1002\/ccr3.73274","archive":["Portico"],"relation":{},"ISSN":["2050-0904","2050-0904"],"issn-type":[{"value":"2050-0904","type":"print"},{"value":"2050-0904","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,8]]},"assertion":[{"value":"2026-02-17","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-07-18","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-08-06","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e73274"}}
