55 Possible Causes for Ventricular Repolarization Abnormalities (ECG)

Did you mean: Ventricular Repolarization Abnormalities (ECG

  • Long QT Syndrome 13

    Introduction The long QT syndrome (LQTS) is a disorder of cardiac ion channel producing prolonged ventricular repolarization; usually diagnosed by prolonged QT interval on[] […] electrocardiograph (ECG).[] LQTS may be congenital (resulting from mutation involving genes encoding cardiac ion channel) or acquired (caused by metabolic abnormalities or drugs).[]

  • Idiopathic Ventricular Fibrillation

    Abstract Recent data point to a high incidence of early repolarization abnormalities among patients with idiopathic ventricular fibrillation (IVF).[] ECG data from 11 patients with idiopathic IVF were evaluated for the presence of initial (slurring or notching of the ascending limb of the R-wave that resembles a "pseudo[]

  • Arrhythmogenic Right Ventricular Dysplasia

    A 56-year-old male with repolarization abnormalities on electrocardiogram (ECG), ventricular arrhythmias, and family history of sudden cardiac death presents with worsening[] We hypothesized that ventricular depolarization and repolarization abnormalities on the 12-lead surface electrocardiogram (ECG) predict adverse outcome in patients with ARVD[] Download Cardiac MRI of Arrhythmogenic Right Ventricular Dysplasia.avi Description: Authors: Sun Moon Kim, MD; Steve Leung, MD, FACC.[]

  • Ventricular Tachycardia

    Polymorphic ventricular tachycardia is usually due to abnormalities of ventricular repolarization of muscle fibers.[] Polymorphic ventricular tachycardia, on the other hand, is most commonly caused by abnormalities of ventricular muscle repolarization.[] Predisposition abnormalities are usually the ventricular tachycardia ecg manifests as QT prolongation, which may be acquired or congenital.[]

  • Early Repolarization Syndrome

    However, it is unclear whether J waves are more strongly associated with a depolarization abnormality rather than a repolarization abnormality.[] , or indeed due to early regional ventricular repolarization.[] Therefore, clinical and ECG data are essential for differential diagnosis.[]

  • Holiday Heart Syndrome

    Although ventricular repolarization abnormalities on surface ECG were described, whether ventricular myocardium responds similarly to ethanol is uncertain.[]

  • Idiopathic Ventricular Fibrillation Not Type Brugada

    However, they showed the similar repolarization abnormality, a finding suggesting the presence of a common underlying electrophysiological abnormality.[] In patients with Brugada type ECG, precordial leads close to the anterior right ventricular wall may be appropriate for the measurement of QT intervals, but we analyzed QT[] Study Limitations In the present study the number of IVF patients was small, and ECG patterns were heterogeneous: 5 patients had Brugada-type and 3 had non-Brugada-type ECG[]

  • Mitral Valve Prolapse

    In some individuals, MVP is silent or associated with palpitations, dizziness, chest pain, and abnormal electrocardiogram (ECG) repolarization with or without ventricular[] However, this report brings to light a potential higher risk cohort of patients with bileaflet MVP, repolarization abnormalities in the inferior ECG leads, and complex ventricular[] Markiewicz-Łoskot et al. [ 3 ] studied electrocardiographic abnormalities in ten young athletes with MVP. Abnormal ECG repolarization was found in seven athletes.[]

  • Hypertensive Retinopathy

    Renal dysfunction, ECG abnormalities (ventricular hypertrophy, pathological Q wave, repolarization abnormalities), and history of stroke were observed in 70.0%, 27.0% and[]

  • Right Bundle Branch Block

    It is still debated whether this ECG pattern is better explained by abnormal repolarization or ventricular conduction and depolarization.[] Conduction diseases can conceal type 1 BS-like ECG in standard V1-V3 leads. ECG alterations were found also in alternative leads.[]
