One month after discharge, the patient returned for a routine defibrillator checkup, and we witnessed AF with a QTc of 412 ms; he remained asymptomatic and had not presented arrhythmias. Figure 2. Cerebral MRI showing empty silla turcica (arrow). [revespcardiol.org]

Asymptomatic male LQTS patients particularly associated with the C-terminal and haploinsufficient LQT1 mutations are at a much lower risk. [thecardiologyadvisor.com]

Torsades de pointes Clinical Significance TdP is often short lived and self terminating, however can be associated with hemodynamic instability and collapse. TdP may also degenerate into ventricular fibrillation (VF). [litfl.com]

However, it is difficult to remember all of these drugs, particularly those noncardiac and weak QT prolonging agents. There are a number of websites where physicians can search online for QT prolonging and other contraindicated medications. [thecardiologyadvisor.com]

Symptoms • Patients with torsades usually present with recurrent episodes of palpitations, dizziness, and syncope. Sudden cardiac death can occur with the first episode. • Nausea, cold sweats, shortness of breath and chest pain may occur. 14. [de.slideshare.net]

Symptoms of torsades de pointes include: heart palpitations dizziness nausea cold sweats chest pain shortness of breath rapid pulse low blood pressure In more serious cases, torsades de pointes can cause lack of consciousness, known as syncope, or even [medicalnewstoday.com]

It is universally associated with congenital or acquired long QTc syndrome (LQTS). 1 Although it is often self limiting and associated with dizziness or syncope, ventricular tachycardia or ventricular fibrillation can occur resulting in sudden cardiac [emj.bmj.com]

Patients with torsades usually present with recurrent episodes of palpitations, dizziness, and syncope. [ 7 ] Sudden cardiac death can occur with the first episode. Nausea, pallor, cold sweats, shortness of breath and chest pain may occur. [patient.info]

Typical symptomes include vertigo, syncopation and nausea. [flexikon.doccheck.com]

These patients would only have symptoms or detected prolonged QT interval when exposed to stimulants like medications, acute illness or electrolyte disturbances. [onlinejacc.org]

Torsade is associated with a prolonged QT interval, which may be congenital or acquired (for example, due to medications, hypokalemia, or hypomagnesemia). [emdocs.net]

When using hydroxyzine: do not prescribe hydroxyzine to people with a prolonged QT interval or who have risk factors for QT interval prolongation (see below) avoid use in the elderly - they are more susceptible than younger patients to the side effects [gov.uk]

A prolonged QT interval in the surface electrocardiogram is the sine qua non of the LQTS and is a surrogate measure of the ventricular action potential duration (APD). [onlinelibrary.wiley.com]
