Intricacies in Serial Electrocardiograms in a Patient With Takotsubo Syndrome Mimicking Apical Hypertrophic Cardiomyopathy

Clinical Case Reports, Volume 14, Issue 8, August 2026.
ABSTRACT Some patients with takotsubo syndrome reveal transiently features of hypertrophic cardiomyopathy at imaging, particularly of the apical variety; this “pseudohypertrophy” is due to myocardial edema, and can be diagnosed by the absence of electrocardiogram evidence of left ventricular hypertrophy, and particularly a transient reduction of the ...

SRM 1650b Administration to Isolated Rat Heart Aggravates Ischemia‐Reperfusion Injury via Mitochondrial Dysfunction and Downregulation of PI3K/Akt Signaling Pathways

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
SRM 1650b diesel particulate matter caused dose‐dependent cardiotoxicity in isolated male Wistar rat hearts, worsening hemodynamics and tissue injury after ischemia–reperfusion. It increased oxidative stress, impaired mitochondrial bioenergetics and respiration, downregulated mitochondrial quality‐control genes, reduced mtDNA copy number, and ...

Metabolic Syndrome as a Determinant of Bidirectional Transitions Between Frailty States: Evidence From the Whitehall II Study

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Understanding interactions between geriatric syndromes is central for promoting healthy aging. Frailty is among the most relevant, as it predicts disability, falls, hospitalization and mortality. In addition, emerging evidence also indicates that metabolic factors play a key role in the frailty development.

Catheter Ablation Outcomes in Electrical Storm Versus Non–Electrical Storm Ventricular Tachycardia: A Systematic Review and Meta‐Analysis

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Catheter ablation for ventricular tachycardia showed comparable acute procedural success and complication rates in patients with and without electrical storm. However, electrical storm was associated with higher in‐hospital mortality, long‐term mortality, and ventricular tachycardia recurrence, supporting its role as a marker of adverse prognosis ...

Diagnostic Accuracy of Electrocardiographic Criteria in Differentiating Arrhythmogenic Right Ventricular Cardiomyopathy From Idiopathic Outflow Tract Ventricular Arrhythmia: A Systematic Review and Meta‐Analysis

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
ECG parameters, particularly depolarization‐based markers, demonstrate high specificity for differentiating ARVC from idiopathic outflow tract arrhythmias. A multi‐marker ECG approach may facilitate accessible early screening and clinical decision‐making, particularly in settings with limited access to advanced imaging.

Stokes–Adams Syncope and Ventricular Standstill

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.
Stokes–Adams syncope has various etiologies including atrioventricular conduction delays, ischemia, or vagal mechanisms. Careful EKG analysis including serial EKGs, may help identify contributory mechanisms to the etiology of syncope, even after permanent pacemaker implantation.
