Spiked Helmet Sign in the Early Post‐Heart Transplantation Period: A Dramatic STEMI Mimic in a Structurally Normal Donor Heart

Annals of Noninvasive Electrocardiology, Volume 31, Issue 6, November 2026.
A 36‐year‐old woman developed Spiked Helmet Sign after heart transplantation complicated by subarachnoid hemorrhage and septic shock. Although the ECG changes resolved, she died from infectious complications, highlighting SHS as a marker of critical illness and poor prognosis.

Sex‐Specific Prevalence and Distribution of Electrocardiographic Variants in Healthy Vietnamese Freshmen

Annals of Noninvasive Electrocardiology, Volume 31, Issue 6, November 2026.
This large‐scale study establishes sex‐specific ECG reference values in healthy young Vietnamese adults, identifying marked male predominance in early repolarization and bundle branch block, while sinus arrhythmia was primarily associated with heart rate and age.

Sex and Age Differences in Electrocardiographic Parameters Among Adults With Normal ECGs at a Single Diagnostic Centre in Owerri, Nigeria: A Retrospective Cross‐Sectional Study

Annals of Noninvasive Electrocardiology, Volume 31, Issue 6, November 2026.
In 313 normal 12‐lead ECGs from Nigerian adults, sex not age was the stronger determinant of cardiac conduction: QRS narrowed with age in men but not women, and QTc was longer in women at both ages. Ceiling truncation of PR/QRS values calls for sex‐specific reference limits.

Early Repolarization Revisited

New England Journal of Medicine, 2008
For more than 60 years, physicians have been fascinated by a peculiar electrocardiographic pattern called “early repolarization.”1 When Google is queried, more than 1 million hits turn up on this subject. Although Boineau recently described the electrocardiographic features of early repolarization as being quite diverse,2 such features have one factor ...

Sudden Cardiac Arrest Associated With Early Repolarization

New England Journal of Medicine, 2008
BACKGROUND: Early repolarization is a common electrocardiographic finding that is generally considered to be benign. Its potential to cause cardiac arrhythmias has been hypothesized from experimental studies, but it is not known whether there is a ...

Malignant Early Repolarization

The American Journal of Cardiology, 2018
A 27-year-old man presents with successfully resuscitated ventricular fibrillation. Structural and electrical causes of ventricular fibrillation in the young are presented along with a diagnostic strategy. Electrocardiographic features of malignant early repolarization are discussed.

A practical guide to early repolarization

Current Opinion in Cardiology, 2015
Early repolarization has been associated in the past decade with idiopathic ventricular fibrillation and arrhythmic death. The purpose of this review is to clarify recent changes in the definition of early repolarization and provide a practical approach to patients with this electrocardiographic sign.Recent population studies have associated early ...

Early Repolarization: Innocent or Dangerous?

The American Journal of the Medical Sciences, 2013
Electrocardiographic (ECG) findings of wide QRS complexes in right precordial leads with saddle ST elevation in patients with polyarthritis, palpitations and family history of syncope urged us to review early repolarization syndrome (ERS). ERS is commonly seen in young men. The main ECG features are as follows: wide spread concave ST-segment elevation,
