Methods This was a case–control study of women admitted in labour to one of eight hospitals of Northwell Health from January 2015 to June 2021. Objectives Examine the association between arrhythmias and adverse maternal outcomes in women with structurally normal hearts. Arrhythmia was previously diagnosed in 58.0% AF and 8.1%

Background Early ventricular tachycardia/fibrillation (VT/VF) in patients with ST-elevation myocardial infarction (STEMI) has higher morbidity and mortality. Methods We analyzed data from 2,964 consecutive STEMI patients between January 1, 2008 and December 31, 2021.

There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). This patient was having recurrent episodes of polymorphic ventricular tachycardia with an underlying long QT interval ( = Torsades des Pointes ).

This is ischemic ST depression, and could be due to increasing tachycardia, with a heart rate over 130, but that is unlikely given that the patient is now complaining of crushing chest pain and that there was tachycardia all along. There is widespread ST depression. Figure-1: Comparison of the first 2 ECGs in today's case.
