426 Possible Causes for Arrhythmias Detected Prenatally, Hyperhidrosis or Diaphoresis, Ventricular Repolarization Abnormalities

  • Tachyarrhythmia

    Overall, these serious tachyarrhythmias comprise less than 10% of arrhythmias detected prenatally.[] The changes seen in electrocardiogram (ECG) consist of repolarization abnormalities such as ST elevation, ST depression, negative T waves, and QT prolongation.[] 8 (11) Repolarization abnormalities 32 (42) Conduction disease 2 (3) Left atrial enlargement 0 Left ventricular hypertrophy 1 (1) Use of antiarrhythmics within 30 d of initial[]

  • Long QT Syndrome 13

    Hsiao et al. [ 30 ] analyzed the outcomes of 123 fetuses with prenatally detected cardiac malformations and/or cardiac arrhythmias.[] RESULTS: Compared with the analysis of the healthy group (n 8), age- and sex-matched pair analysis revealed that the mutation carriers (n 8) had ventricular repolarization[] The ECG revealed a sinus rhythm with normal voltages, but with a QTc interval of 500 ms (calculated by Bazett's formula) and repolarization abnormalities with negative T waves[]

  • Heart Failure

    (ii) The effects of drugs or electrolyte abnormalities must be considered as possible noncardiac causes of ECG abnormalities of ventricular repolarization; that is, those[]

  • Myocardial Infarction

    No repolarization abnormalities are seen in other leads.[] Left ventricular (LV) hypertrophy, bundle-branch blocks with repolarization abnormalities, and ventricular pacing may mask signs of ischemia/injury. 62 3.2.4.[] Right-sided leads (V 3 R to V 4 R) are typically performed in the case of inferior STEMI to detect evidence of right ventricular infarction.[]

  • Common Cold

    The common cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the nose. The throat, sinuses, and larynx may also be affected. Signs and symptoms may appear less than two days after exposure to the virus. These may include coughing, sore throat,[…][]

  • Alcoholic Cardiomyopathy

    Criteria associated with LV hypertrophy with a repolarization abnormality, prolonged repolarization (ie, QT interval), nonspecific ST- and T-wave changes, and Q waves have[] A 24-hour Holter examination revealed permanent atrial fibrillation but no ventricular repolarization or heart rate abnormalities.[] Other supraventricular tachyarrhythmias and sudden death have also been associated with alcohol use and AC, with the latter being most likely secondary to the development of ventricular[]

  • Upper Respiratory Infection

    The combination of nasal congestion, rhinorrhea, sore throat, cough, and malaise is the symptomatic profile that constitutes an uncomplicated upper respiratory tract infection (URI), also known as the common cold. Because no known cure exists for a URI, numerous products are available, each marketed with the[…][]

[11] One study used ajmaline provocation to elicit a type 1 Brugada ECG pattern in 91 patients, and found that the repolarization abnormalities were concordant[] […] disorder model, proposes that the typical Brugada ECG findings can be explained by slow conduction and activation delays in the right ventricle (in particular in the right ventricular[]

  • Incessant Infant Ventricular Tachycardia

    Supraventricular Tachycardia SVT is the most common serious arrhythmia detected prenatally. It accounts for about 6% of referrals, as shown in Table 2.[] Ventricular tachycardia may also occur in children with long QT-syndrome wich is a familial disease carachterized by prolonged and abnormal ventricular repolarization and[] They often are detected during routine auscultation at a prenatal visit.[]
