likely that the ketogenic diet, rather than a congenital long QT syndrome, was responsible for the observed repolarization abnormalities. Cases of abnormal electrical conduction in the heart and convulsion have been on heart rate, atrioventricular (AV) conduction and cardiac repolarization.

Electrical Remodeling of Ventricular Repolarization Abnormality after Treatment in Pheochromocytoma: U Wave Finding in a Retrospective Analysis Giuseppe Di Stolfo , 1 Sandra Mastroianno , 1 Angela Maggio , 2 Giovanni De Luca , 1 Domenico R. Potenza , 1 Mauro Pellegrino Salvatori , 1 and Aldo Russo 1 To evaluate repolarization lability, vectorcardiography (VCG) is an alternative approach where the electrocardiographic (ECG) signal can be considered as possessing both magnitude and direction. Recent research has shown that VCG is advantageous over ECG signal analysis for identification of repolarization abnormality. It demonstrates a strain pattern (or repolarization abnormality) with left ventricular hypertrophy. The good news is that it’s a very typical looking strain pattern! Since this 12 lead ECG is not in the standard U.S. format, I used “cut” and “paste” to structure it into a pattern more typical of prehospital 12 lead ECGs in the U.S. The T-peak–T-end Interval as a Marker of Repolarization Abnormality: A Comparison with the QT Interval for Five Different Drugs. Research output: Contribution to journal › Journal article › Research › peer-review T1 - A characteristic precordial repolarization abnormality with intermittent left bundle-branch block.

The method can include deriving a total quantity of representative beats of the at least one electrocardiogram signal. Repolarization (ST-T,U) Abnormalities Early repolarization (normal variant) Juvenile T waves (normal variant) Nonspecific abnormality, ST segment and/or T wave ST and/or T wave suggests ischemia ST suggests injury ST suggests ventricular aneurysm Q-T interval prolonged Prominent U waves Cardiac If a repolarization abnormality is present in a lead, it should be negative if the delta wave is positive and vice versa. Therefore, the repolarization abnormality points opposite to the direction of the delta wave. So, the question really isn't whether the repolarization abnormality should be opposite the terminal or the main deflection of the Recently, certain forms of early repolarization (ER) on electrocardiograms (ECGs) have been considered a possible marker of increased sudden cardiac death risk. The frequency, characteristics, and clinical follow‐up with which these forms of ER are present in epilepsy patients, and whether or not abnormal ER contributes to sudden unexplained death in epilepsy patients (SUDEP) is unknown.

Recently, certain forms of early repolarization (ER) on electrocardiograms (ECGs) have been considered a possible marker of increased sudden cardiac death risk. BACKGROUND: Analysis of electrocardiographic (ECG) repolarization abnormality using QTc interval and principal component analysis (PCA) of the T-wave vector predict all-cause and cardiovascular (CV) mortality. Novel descriptors of T-wave morphology have been suggested as measures of repolarization heterogeneity and Life-threatening arrhythmia in the setting of QT prolongation occurs as a result of inherited mutations in ion channel genes or, more commonly, as a consequence of drugs that affect cardiac repolarization. 1,2 This latter mechanism is the focus of increasing regulatory attention as several pharmaceuticals have been withdrawn from the US market due to torsades de pointes (TdP). The 12-lead electrocardiogram (ECG) shows a spectrum of alterations in young, trained athletes, including, most commonly, repolarization abnormalities and increased R- or S-wave voltage suggestive Less understood but recently highlighted are abnormalities of phase 1 (Early Repolarization).
