Acquired long QT syndrome is an important and preventable cause of cardiac arrest. Certain medications and electrolyte disturbance are common contributors, and often coexist. In this case, we report five contributors to cardiac arrest.

Cesium is an inorganic compound, which is not approved by the Food and Drug Administration (FDA), and is available as over-the-counter (OTC) drug. Despite lack of supportive data on efficacy, and evidence of safety of the cesium, this drug is used by the patients for treatment of cancer depression and other conditions.

QT prolongation is present in 26-52% of cases of Takotsubo cardiomyopathy (TCM). It has been postulated to result from reduced cardiac repolarization reserve and reflects the transient myocardial insult observed in TCM. Bradycardia-induced QT interval prolongation is amplified by the occurrence of TCM, a combination that potentially carries a significant risk for torsade de pointes (TdP).

Hospitalized patients have a high prevalence of prolonged QTc and are a high-risk population for Torsades de Pointes (TdP). One modifiable risk factor for TdP is the use of QT prolonging drugs. Electronically alerting providers who are ordering QT prolonging drugs in at-risk patients may help to achieve safer prescribing practices.

Identifying acute events as they occur is challenging in large hospital systems. Here, we describe an automated method to detect 2 rare adverse drug events (ADEs), drug-induced torsades de pointes and Stevens-Johnson syndrome and toxic epidermal necrolysis, in near real time for participant recruitment into prospective clinical studies.

This case demonstrates the severe electrolyte derangements that may present after a common therapy such as a bowel preparation for an outpatient procedure and the rare yet potential detrimental outcomes of those abnormalities. It also highlights the implications of long QT syndrome regarding pharmacology and treatment.

Torsade de pointes (TdP) is a malignant arrhythmia that can be induced by QT internal prolongation due to a variety of factors. Here we report an elderly patient with advanced non-small cell lung cancer (NSCLC) had sudden TdP during hospitalization, which was caused by multiple factors such as osimertinib, moxifloxacin and patient self-factors.

Blockage of some ion channels and in particular, the hERG (human Ether-a’-go-go-Related Gene) cardiac potassium channel delays cardiac repolarization and can induce arrhythmia. In some cases it leads to a potentially life-threatening arrhythmia known as Torsade de Pointes (TdP).

Drugs not commonly considered to be cardioactive agents may cause prolongation of the QT interval with resultant torsades de pointes and ventricular fibrillation. This form of drug toxicity often causes cardiac arrest or sudden death.

ECG with no association between the QRS complex and the P wave. The child is often symptomatic, presenting with acute collapse. Ventricular tachyarrhythmias are often associated with underlying heart disease such as cardiomyopathy. Torsades de Pointes is a particular form of sinusoidal ventricular arrhythmia that occurs in the rare congenital long QT syndrome.

Xoắn đỉnh (Torsade de Pointes) ... là một rối loạn nhịp thất trung gian giữa nhịp nhanh thất và rung thất, xuất hiện do cơ chế vào lại (ré-entreé). Nếu do độc digoxin, lạm dụng furosemit cần bù kali kịp thời sẽ cải thiện nhanh nguy cơ rung thất; nhưng nếu do biến chứng từ nhịp chậm vì block AV độ III - thì phải dùng isuprel và đặt máy tạo nhịp... Xoắn đỉnh là một loại nhịp nhanh thất đặc biệt không bền bỉ có từng đợt QRS đa hình hay tái phát, cơn có kèm ngất thậm chí...

Bài này nói về một trong những thuốc trong mộṭ họ thuốc (family) rất thường dùng (hàng ngày) trong oncology để control NV (nausea and vomiting). Thật sự đây là một họ thuốc xứng đáng là breakthrough (phá nghẽn) cho NV, vì trước đó, các thuốc khác không hiệu quả bằng. Warnings (Cảnh báo) này đáng nhớ về torsade de pointes và QTprolongation. Về hypomagnesemia, complication này thường thấy trong khi dùng patinum-based chemotherapy (tubular wasting). ...
