  2. Brugada syndrome - Wikipedia

    en.wikipedia.org/wiki/Brugada_syndrome

    Three forms of the Brugada ECG pattern have historically been described, [34] although the Type 3 pattern is frequently merged with the Type 2 pattern in contemporary practice. [35] Type 1 has a coved type ST elevation with at least 2 mm (0.2 mV) J-point elevation and a gradually descending ST segment followed by a negative T-wave. [35]

  3. Long QT syndrome - Wikipedia

    en.wikipedia.org/wiki/Long_QT_syndrome

    Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]

  4. Sudden arrhythmic death syndrome - Wikipedia

    en.wikipedia.org/wiki/Sudden_arrhythmic_death...

    Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults caused by a cardiac arrest. However, the exact cause of the cardiac arrest, and thus the exact cause of death, is unknown. These deaths occur mainly during sleep or at rest. [7] One type of conduction defect known as Brugada syndrome can be ...

    ECG pattern in Brugada syndrome. According to recent consensus document (ref 13), type 1 ST segment elevation either spontaneously present or induced with Ajmaline/Flecainide test is considered diagnostic. Type 1 and 2 may lead to suspicion but drug challenge is required for diagnosis.

  6. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Cardiac arrest (also known as ... (LQTS), Brugada Syndrome, ... Circadian patterns are also recognized as triggering factors in cardiac arrest. [55]

  7. Short QT syndrome - Wikipedia

    en.wikipedia.org/wiki/Short_QT_syndrome

    The syndrome gets its name from a characteristic feature seen on an electrocardiogram (ECG) – a shortening of the QT interval. It is caused by mutations in genes encoding ion channels that shorten the cardiac action potential, and appears to be inherited in an autosomal dominant pattern. [1] The condition is diagnosed using a 12-lead ECG. [2]

  9. Ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Ventricular_fibrillation

    Recently described syndromes such as the Brugada Syndrome may give clues to the underlying mechanism of ventricular arrhythmias. In the Brugada syndrome, changes may be found in the resting ECG with evidence of right bundle branch block (RBBB) and ST elevation in the chest leads V1–V3, with an underlying propensity to sudden cardiac death.
