79 Possible Causes for Prolonged QT Interval, Ventricular Bigeminy

  • Cardiomyopathy

    Frequent ventricular ectopics and ventricular bigeminy (seen with severe DCM). Ventricular dysrhythmias ( VT / VF ).[lifeinthefastlane.com]

  • Hypomagnesemia

    The patient exhibited sinus bradycardia (48 b.p.m.) with intermittent supraventricular contraction on postpartum day 2, intermittent ventricular bigeminy on postpartum day[ncbi.nlm.nih.gov] The others had electrocardiogram abnormalities (prolonged QT interval, ST depression, and U waves).[ncbi.nlm.nih.gov] Her electrocardiogram disclosed typical, prolonged QT interval, ST depression, and U waves.[ncbi.nlm.nih.gov]

  • Torsades De Pointes

    […] ablation of incessant right ventricular outflow tract bigeminy.[ncbi.nlm.nih.gov] TdP generally occurs in conjunction with a prolonged QT interval (QT) on the electrocardiogram.[ncbi.nlm.nih.gov] A 12-lead electrocardiogram revealed a new prolonged QT c interval of 619 min.[academic.oup.com]

  • Premature Ventricular Contraction

    Example 3) Ventricular Bigeminy ECG (Example 1) Ventricular Bigeminy ECG (Example 2) Ventricular Bigeminy ECG (Example 3) Ventricular Trigeminy ECG (Example 1) Ventricular[healio.com] […] or a prolonged QT interval. children left ventricular function premature ventricular contraction This is a preview of subscription content, log in to check access.[link.springer.com] Voltage maps were acquired at baseline and after 14 weeks of ventricular bigeminy.[ncbi.nlm.nih.gov]

  • Hypokalemia

    Changes include: U waves (most important; represents delayed ventricular repolarization) flattened or inverted T waves depressed ST segment prolonged QT interval Prolonged[sharinginhealth.ca] SCN5A-1103Y was associated with QT interval prolongation (2.7 milliseconds; P .001) and potentiated the effect of hypokalemia on QT interval prolongation (14.6 milliseconds[ncbi.nlm.nih.gov] Replete cautiously Take Home Points Severe hypokalemia can lead to lethal dysrhythmias typically by prolongation of the QT interval.[coreem.net]

  • Coronary Artery Disease

    Although side effects are relatively uncommon, ranolazine can prolong the QT interval, increasing the risk for polymorphic ventricular tachycardia (Torsades de Pointes).[healio.com]

  • Dofetilide

    He experienced an 8-beat run of non-sustained ventricular tachycardia, frequent multifocal PVCs, and ventricular bigeminy.[ncbi.nlm.nih.gov] Like other drugs that affect potassium currents, the prolonged QT interval occurring in the patients treated with dofetilide can be complicated by torsades de pointes.[ncbi.nlm.nih.gov] Of the 36 patients in Group I who started dofetilide before ablation, three stopped it prior to ablation (one for ventricular bigeminy, one for bradycardia, and one due to[academic.oup.com]

  • Arsenic Trioxide

    Ventricular premature beat bigeminy developed on day 27 of treatment, and episodes of TdP developed on day 28.[ncbi.nlm.nih.gov] Such patients should be monitored for prolonged QT intervals and ventricular arrhythmia.[annals.org] Cardiovascular toxicity is known to occur with this therapy, in particular heart rhythm disorders due to QT interval prolongation.[ncbi.nlm.nih.gov]

  • Ventricular Tachycardia

    Example 4 Monomorphic VT alternates with ventricular bigeminy. The ventricular complexes have the following features: Very broad QRS duration ( 160 bpm).[lifeinthefastlane.com] The patient's initial electrocardiogram was remarkable for a prolonged QT interval, and it was discovered that multiple family members had died of cardiac events as young[ncbi.nlm.nih.gov] […] contractions or ventricular bigeminy, despite the absence of sustained high rates. [20] Etiology Causes of ventricular tachycardia (VT) include the following [ 11 ] : Ischemic[emedicine.medscape.com]

  • Methadone

    We report a case of ventricular bigeminy with concomitant administration of methadone, voriconazole and esomeprazole in a Caucasian woman aged 26 with acute lymphoblastic[ncbi.nlm.nih.gov] Treatment of TdP by antiarrhythmic drugs that prolong QT interval may worsen TdP.[ncbi.nlm.nih.gov] People with a personal or family history of an abnormal heart rhythm, seen on a heart monitoring trace (ECG) as a 'prolonged QT interval', and people taking other medicines[netdoctor.co.uk]
