1,776 Possible Causes for Arrhythmias Detected Prenatally, Cardiac Signs and Symptoms, Ventricular Repolarization Abnormalities

  • Long QT Syndrome 13

    Hsiao et al. [ 30 ] analyzed the outcomes of 123 fetuses with prenatally detected cardiac malformations and/or cardiac arrhythmias.[] Another serious symptom of long QT syndrome is unexplained sudden cardiac arrest. With sudden cardiac arrest, a person’s heart stops beating for no apparent reason.[] 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[]

  • Tachyarrhythmia

    Overall, these serious tachyarrhythmias comprise less than 10% of arrhythmias detected prenatally.[] Cardiac tumours are rare in childhood and should be considered as part of the differential diagnosis in a child presenting with cardiac signs and symptoms and treatment should[] The changes seen in electrocardiogram (ECG) consist of repolarization abnormalities such as ST elevation, ST depression, negative T waves, and QT prolongation.[]

  • Holiday Heart Syndrome

    They further noted that, for patients visiting the emergency room with palpitations or other symptoms associated with cardiac arrhythmias, a “high suspicion of HHS should[] Although ventricular repolarization abnormalities on surface ECG were described, whether ventricular myocardium responds similarly to ethanol is uncertain.[] […] occur” if the patient exhibits signs of being intoxicated or admits to a recent episode of binge drinking.[]

  • Early Repolarization Syndrome

    There are no specific signs or symptoms attributed to the ER pattern, which is identified through the use of a standard ECG.[] […] myocardium; T wave tells about the features of ventricular repolarization - abnormalities and are a symptom of the disorder.[] However, it is unclear whether J waves are more strongly associated with a depolarization abnormality rather than a repolarization abnormality.[]

  • Cardiac Arrhythmia

    The signs and symptoms of cardiac arrhythmias can range from completely asymptomatic to loss of consciousness or sudden cardiac death.[] In cardiac patients, life-threatening tachyarrhythmia is often precipitated by abnormal changes in ventricular repolarization and refractoriness.[] In many instances, cardiac arrhythmia may not produce any signs or symptoms.[]

  • Hyperkalemia

    Signs and symptoms Patients with hyperkalemia may be asymptomatic, or they may report the following symptoms (cardiac and neurologic symptoms predominate): Generalized fatigue[] Electrocardiographic manifestations of hyperkalemia vary from the classic sine-wave rhythm, which occurs in severe hyperkalemia, to nonspecific repolarization abnormalities[] abnormalities : Peaked T waves (usually the earliest sign of hyperkalaemia) Serum potassium 6.5 mEq/L is associated with progressive paralysis of the atria : P wave widens[]

  • Long QT Syndrome

    Most people who experience sudden cardiac arrest die. In about 1 out of 10 patients, sudden cardiac arrest or death is the first sign of LQTS.[] 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 abnormality[] Abstract Long QT syndrome (LQTS) is an arrhythmogenic disorder characterized by repolarization abnormalities with a tendency to cause life threatening cardiac events.[]

  • Arrhythmogenic Right Ventricular Dysplasia

    Cardiac arrest Peripheral edema Sudden death Tachycardia TABLE 1 Signs and Symptoms of ARVD Symptoms Abdominal pain Decreased exercise tolerance Dizziness Dyspnea (especially[] We hypothesized that ventricular depolarization and repolarization abnormalities on the 12-lead surface electrocardiogram (ECG) predict adverse outcome in patients with ARVD[] A 56-year-old male with repolarization abnormalities on electrocardiogram (ECG), ventricular arrhythmias, and family history of sudden cardiac death presents with worsening[]

  • Cardiomyopathy

    Like HCM, it can cause sudden cardiac arrest in young athletes. What are the signs and symptoms? Some people who have cardiomyopathy never have signs or symptoms.[] Clinical diagnosis may be achieved by demonstrating functional and structural alterations of the right ventricle, depolarization and repolarization abnormalities, arrhythmias[] Signs and symptoms Signs and symptoms of HCM can include the following: Sudden cardiac death (the most devastating presenting manifestation) Dyspnea (the most common presenting[]

  • Acute Myocardial Infarction

    Documentation Suggestions Describe clinical signs and symptoms (e.g., crescendo angina, fourth heart sound, left ventricular failure, pain radiating to left arm, etc.).[] Electrocardiography showed new repolarization abnormalities in aVF and III.[] This is referred to as “LVH with strain” or “LVH with repolarization abnormality.”[]
