QT Interval Abnormalities with Pulmonary Emboli

Tricuspid endocarditis with pulmonary emboli.

Right-sided endocarditis accounts for 5–10% of all cases of infective endocarditis.1 Its epidemiology, diagnosis, and treatment differ from that of left-sided endocarditis, making it a distinct entity. This article presents a case of tricuspid valve endocarditis in an intravenous drug user, and discusses the presentation, diagnosis, and therapeutic considerations unique to right-sided endocardi...

Chronic Arsenic Exposure and Cardiac Repolarization Abnormalities with QT Interval Prolongation in a Population-based Study

BACKGROUND Chronic arsenic exposure is associated with cardiovascular abnormalities. Prolongation of the QT (time between initial deflection of QRS complex to the end of T wave) interval and profound repolarization changes on electrocardiogram (ECG) have been reported in patients with acute promyelocytic leukemia treated with arsenic trioxide. This acquired form of long QT syndrome can result i...

Bilateral pulmonary emboli.

To cite: Galante O, Lador N, Schwarzfuchs D. BMJ Case Reports Published online: 17 December 2012 doi:10.1136/bcr-2012007827 DESCRIPTION A 79-year-old woman presented with an aggravating effort dyspnoea during the preceding week. On examination, her oxygen saturation was 87% while breathing ambient air; her blood pressure was 120/75; she had distended neck veins; normal breath sounds and regular...

[Corrected QT interval and corrected QT interval dispersion is worthwhile when interpreted with other repolarization measurements].

We read the article entitled ‘‘The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor’’ by Ceker et al. with interest.1 The authors investigated the effects of esmolol on the hemodynamic, correctedQT (QTc) interval and corrected-QT interval dispersion (QT...
