Torsade de pointes, prolonged QT intervals, and patients with cancer.
نویسنده
چکیده
Many kinase inhibitors, chemotherapeutic agents, antiemetics, antibiotics, and antifungal agents can prolong QT intervals, placing the patient as risk for the life-threatening ventricular arrhythmia Torsade de pointes (Tdp). In addition, common electrolyte imbalances experienced by many patients with cancer compound the risk. Because numerous medications used in oncology and common electrolyte imbalances in patients with cancer increase the risk for Tdp, oncology nurses must be informed about this life-threatening arrhythmia.

Background. Patients with a history of class Ia drug-induced torsade de pointes have been treated with chronic amiodarone without recurrence of torsade de pointes despite comparable prolongation of the QT interval. We hypothesized that in such patients, class la drugs cause nonhomogeneous prolongation of cardiac repolarization times, whereas amiodarone causes homogeneous prolongation of cardiac...

Çongenital long-QT syndrome (LQTS) is an inherited disorder that presents with syncope, polymorphic ventricular tachycardia, torsade de pointes and sudden death. The incidence rate of LQTS is 1 to 2 per 100000 and mainly involves children and young individuals. Because of familial and genetic underling and predisposing factors for life threatening arrhythmias in patients, diagnosis and treatm...
متن کاملVentricular arrhythmias complicating weight reduction therapy in a patient with a prolonged QT interval.
Serious ventricular arrhythmias are known to occur in patients with long QT intervals. We describe a case of torsade de pointes occurring in a patient with a prolonged QT interval while taking a 1000 calorie diet, diethylpropion hydrochloride (Tenuate Dospan) and bendrofluazide. In patients with long QT intervals, hypokalaemia and drugs which further delay repolarization may facilitate the deve...
