Overview
Risk Factors
Factors that are associated with an increased tendency toward torsades de pointes include:
- Familial long QT syndrome
- Class IA antiarrhythmics
- Hypomagnesemia
- Hypokalemia
- Hypoxia
- Acidosis
- Heart failure
- Left ventricular hypertrophy
- Slow heart rate
- Female gender
- Baseline electrocardiographic abnormalities
- Renal or liver failure
Clinical Correlation
- Drugs: quinidine, PCA, norpace, amiodarone, phenothiazines, Tricyclic antidepressants, pentamidine.
- with quinidine majority of the cases occur within one week of initiation, and with therapeutic levels
- Electrolyte imbalances: Hypokalemia, hypomagnesemia, hypocalcemia
- CAD
- MVP
- Variant angina
- Myocarditis
- Subarachnoid hemorrhage
- Congenital QT prolongation
- Liquid protein diets
- Hypothyroidism
- because of bradycardia and a prolonged QT syndrome
- Organophosphate poisoning [1] [2]
