Splet10. avg. 2024 · The authors defined “short-coupled ventricular fibrillation” as otherwise unexplained VF initiated by a trigger premature ventricular contraction (PVC) with a coupling interval of <350 ms. Results: There were 364 unexplained cardiac arrest survivors, and 24/364 (6.6%) met the above diagnostic criteria for SCVF. SpletShe had frequent ventricular extrasystoles (with short-coupled period <300 ms) preceding the tachycardia. After administration of isoprenaline infusion electric stability was maintained. In this setting and in the absence of structural heart disease or iatrogenic cause, a diagnosis of short-coupled variant torsade de pointes was established.
