766 Possible Causes for Prolonged QT Interval

  • Cardiomyopathy

    interval prolongation, T wave inversion, abnormal Q waves , nonspecific abnormalities Laboratory: troponin T ; , BNP Echocardiography : apical left ventricular ballooning[amboss.com] […] physical stress massive catecholamine discharge ; cardiotoxicity, multi-vessel spasms and dysfunction myocardial stunning Clinical findings : Diagnostics ECG : ST elevation , QT[amboss.com]

  • Chronic Kidney Insufficiency

    Abstract Anemia is a major problem in patients with chronic kidney insufficiency. The development of recombinant human erythropoietin has enabled physicians to correct this anemia. Although anemia has not been considered to be a common or important contributor to congestive heart failure, anemia of any cause can[…][ncbi.nlm.nih.gov]

  • Torsades De Pointes

    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] We present the case of a patient who followed a hypocaloric diet and developed a prolonged QT interval and torsades de pointes.[revespcardiol.org]

  • Acute Kidney Failure

    Deposits of iron and hemosiderosis in the kidney have been observed in diseases with intravascular hemolysis, including paroxysmal nocturnal hemoglobinuria, and valvular heart diseases and prosthetic heart valve implants. However, the decrease in kidney function associated with hemolysis caused by cardiac valvular[…][ncbi.nlm.nih.gov]

  • Coronary Artery Disease

    The literature concerning heart surgery after pneumonectomy is still poor. Moreover, there is still a lack of a standardized approach to such a patient in the decision-making process. Here, we report a case of a patient who had previously had left pneumonectomy for malignancy and who had coronary artery disease[…][ncbi.nlm.nih.gov]

  • Long QT Syndrome

    […] as indicated by the prolonged qt interval.[icd9data.com] Prolonged QT interval may be associated with torsades de pointes and lead to sudden cardiac death.[ncbi.nlm.nih.gov] A prolonged QT interval in the surface electrocardiogram is the sine qua non of the LQTS and is a surrogate measure of the ventricular action potential duration (APD).[ncbi.nlm.nih.gov]

  • Cardiopulmonary Resuscitation

    Prolongation of QT interval with myocardial contusion. Heart Lung 1978 ; 7 : 652 –6. Blair E, Topuzlu C, Davis JH. Delayed or missed diagnosis in blunt chest trauma.[web.archive.org]

  • Subarachnoid Hemorrhage

    […] the QT interval sinus bradycardia Three distinct patterns of subarachnoid hemorrhage have been described each with their own etiology and treatment/prognostic implications[radiopaedia.org] Thereafter, the ST-segment elevation gradually improved, and the QT interval was prolonged.[circ.ahajournals.org] Other possible ECG abnormalities include prolongation of the QRS or QT intervals and peaking or deep, symmetric inversion of T waves.[merckmanuals.com]
