  2. Catecholaminergic polymorphic ventricular tachycardia

    en.wikipedia.org/wiki/Catecholaminergic...

    Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited genetic disorder that predisposes those affected to potentially life-threatening abnormal heart rhythms or arrhythmias. The arrhythmias seen in CPVT typically occur during exercise or at times of emotional stress, and classically take the form of bidirectional ...

    en.wikipedia.org/wiki/Ventricular_tachycardia

    Ventricular tachycardia can occur due to coronary heart disease, aortic stenosis, cardiomyopathy, electrolyte problems (e.g., low blood levels of magnesium or potassium), inherited channelopathies (e.g., long-QT syndrome), catecholaminergic polymorphic ventricular tachycardia, arrhythmogenic right ventricular dysplasia, alcohol withdrawal ...

  4. Torsades de pointes - Wikipedia

    en.wikipedia.org/wiki/Torsades_de_pointes

    It is a polymorphic ventricular tachycardia that exhibits distinct characteristics on the electrocardiogram (ECG). It was described by French physician François Dessertenne in 1966. [ 3 ] Prolongation of the QT interval can increase a person's risk of developing this abnormal heart rhythm, occurring in between 1% and 10% of patients who ...

    Causes of SADS in young people include viral myocarditis, long QT syndrome, Brugada syndrome, Catecholaminergic polymorphic ventricular tachycardia, hypertrophic cardiomyopathy and arrhythmogenic right ventricular dysplasia. [17] [18]

  6. Drug-induced QT prolongation - Wikipedia

    en.wikipedia.org/wiki/Drug-induced_QT_prolongation

    Class III antiarrhythmic drugs are potassium channel blockers that cause QT prolongation and are associated with TdP. Amiodarone. Amiodarone works in many ways. It blocks sodium, potassium, and calcium channels, as well as alpha and beta adrenergic receptors. Because of its multiple actions, amiodarone causes QT prolongation but TdP is rarely ...

    Diaz noted that this was an observational study, and as a result, cannot prove that sitting was the cause of the heart disease. However, muscles are vital in regulating blood sugar and fat levels ...

  9. Tachycardia - Wikipedia

    en.wikipedia.org/wiki/Tachycardia

    Ventricular tachycardia (VT or V-tach) is a potentially life-threatening cardiac arrhythmia that originates in the ventricles. It is usually a regular, wide complex tachycardia with a rate between 120 and 250 beats per minute.
