1. On her death certificate the causes were listed as syncope and cardio-vascular degeneration.
2. VT has long been recognised as a complication of severe bradyarrhythmias, and less commonly can be the cause of syncope and death in patients with complete atrioventricular block or sinus node dysfunction.
3. Syncope is unrelated to plasma concentrations of quinidine or duration of therapy, and torsades de pointes can occur at low ("subtherapeutic") plasma concentrations.
4. Patients with congenital LQTS can present during childhood with syncope due to torsades de pointes, often precipitated by heightened sympathetic tone - eg, from exertion or fright or as a result of being startled.
5. The VT is commonly non-sustained but sometimes persists long enough to provoke syncope, or even death if ventricular fibrillation supervenes.
6. For patients with idiopathic LQTS who do not have syncope, complex ventricular arrhythmias, or a family history of sudden cardiac death, no therapy is required.
7. Antiarrhythmic drugs - Among type 1a antiarrhythmic drugs, quinidine seems to have the greatest potential for causing torsades de pointes and is estimated to produce syncope in 0.5-;4.0% of patients as a result of this tachyarrhythmia.
8. Quinidine prolongs the QT interval in most patients, whether or not ventricular arrhythmias occur, but significant QT prolongation (500-;600 ms) is more often a characteristic of patients with quinidine syncope.
9. Patients at increased risk include those with family members who died suddenly at an early age and those who have experienced syncope.
10. The frequency with which arrhythmias and syncope occur varies considerably, from several times a day to less than once every several years.
11. In patients with syncope, beta-blockers at maximally tolerated doses can be tried, perhaps in combination with a class 1b antiarrhythmic agent.
12. The principal manifestation of the syndrome is syncope or presyncope, often accompanied by palpitations.
13. During the first 24 hours in hospital, he had three sustained episodes of ventricular tachycardia, at a rate of 200 per minute, associated with circulatory collapse and syncope.
