Torsades de pointes (Figur 56 B) startar inte sällan till följd av ett ventrikulärt exraslag som kommer tidigt i hjärtcykeln. Risken för torsades de pointes ökar vid bradykardi. I samband med denna arytmi brukar individen erfara synkope eller presynkope men arytmin upphör oftast spontant (oftast inom 30 sekunder) Torsades de pointes, även torsade de pointes, är en speciell variant av ventrikeltakykardi (VT), en form av hjärtarytmi.. Torsade de pointes är en ovanlig och allvarlig form av VT. Torsades de pointes orsakas vanligen av antiarytmiläkemedel som förlänger den tid hjärtmuskelcellen behöver för att dra ihop sig och på nytt aktiveras - Endast extremitetsavledningarna visas. SInusrytm, frekvens 55 slag/min. Mycket lång QT-tid, 740 ms, QTc 710 ms. Hög risk för torsade de pointes VT. Misstänkt lång QT - Sinusrytm 85 slag/min - PQ-tid 0,19 s, normal - Bröstavledningars R-S-transition förskjuten åt höger, ospecifi Torsade de pointes är en sällsynt komplikation till tablettintoxikation, men QTc-förlängning är vanligt och Giftinformationscentralen får ofta frågor om handläggningen. Behandlingen av läkemedels­utlöst torsade de pointes är väldokumenterad, däremot har det saknats indikationer för arytmiövervakning och för åtgärder som förhindrar torsade de pointes vid intoxikationer med.

Det är dock förenat med en ca 3 % risk för proarytmi (framför allt polymorf VT av typen torsades de pointes). Förmaksfladder är tacksamt att elkonvertera och som regel behövs betydligt lägre strömstyrka än vid förmaksflimmer (50-100J mono/bifasiskt) Hjärtklappning, takykardi och oregelbunden hjärtrytm förekommer men är inte särskilt vanligt. Dock bör man vara observant på att förlängd QT-tid förekommer och att maligna arytmier kan uppträda som ventrikeltakykardi och Torsade de Pointes-arytmi. I många fall är QT-förlängningen mycket begränsad och saknar klinisk relevans Torsades de pointes, torsade de pointes or torsades des pointes (TdP) (/ t ɔː ˌ s ɑː d d ə ˈ p w æ̃ t /, French: [tɔʁsad də pwɛ̃t̪], translated as twisting of peaks) is a specific type of abnormal heart rhythm that can lead to sudden cardiac death.It is a polymorphic ventricular tachycardia that exhibits distinct characteristics on the electrocardiogram (ECG) Torsade de Pointes, TdP. Breddökad takykardi som vrider sig runt sin egen axel. Uppträder vid förlängd QT-tid som kan vara medfödd (sällsynt) eller förvärvad, ofta orsakat av läkemedel.

The treatment of torsades de pointes is very effective but also very specific. Prompt recognition of torsades de pointes is imperative, and the clue to its recognition is increased awareness. The QT interval in the long QT syndrome (LQTS) is not only prolonged but also odd looking. This abnormal QT Torsades de pointes is a specific form of polymorphic ventricular tachycardia in patients with a long QT interval. It is characterized by rapid, irregular QRS complexes, which appear to be twisting around the electrocardiogram (ECG) baseline. This arrhythmia may cease spontaneously or degenerate into ventricular fibrillation

Torsades de pointes is a specific form of polymorphic ventricular tachycardia that occurs in the presence of prolongation of the QT interval. It has a very characteristic appearance in which the QRS complex appears to twist around the isoelectric baseline. A prolonged QT interval reflects prolonged myocayte repolarisation due to ion channel malfunction and also gives rise to early after. Moxifloxacin-induced torsades de pointes.

What is Torsades de Pointes (TdP)? Disclaimer: This material should be used to supplement your understanding of the cardiovascular system.Any use of the information given in this post series is at your own risk and should be verified prior to making it a part of your nursing practice The term torsade de pointes refers to polymorphic ventricular tachycardia that occurs in the setting of an abnormally long QT interval. While the most common cause is treatment with QT prolonging drugs, torsade de pointes also occurs in the congenital long QT syndromes and in the setting of acquired heart block or severe electrolyte disturbance, notably hypokalemia From a pharmacy perspective, most medications can cause QTc prolongation (which almost always precedes Torsades de Pointes) by blocking the cardiac potassium channels 3. Some antimicrobials that are commonly prescribed in the inpatient and outpatient setting that we should be aware of when thinking about QTc prolongation and Torsades de Pointes are the macrolides, fluoroquinolones, and azoles RESULTS: All drugs that cause torsade de pointes prolong the QTc interval and bind to the potassium rectifier channel, but the relationships are not precise. Prediction of torsade de pointes and sudden death can be improved by examining dose dependency, the percent of QTc intervals higher than 500 msec, and the risk of drug-drug interactions

Torsades de pointes Långt QT-syndrom: Ett syndrom som kännetecknas av synkopeepisoder och ett långt QT-intervall som ibland kan leda till plötslig hjärtdöd, till följd av paroxysmal kammararytmi.En variant som är förknippad med autosomalt recessiv ärftlighet och medfödd dövhet kallas Jervell-Lange Nielsen-syndromet Torsades De Pointes 1. Torsades de pointes Torsades de pointes , or simply torsades is a French term that literally means twisting of the points. It was first described by Dessertenne in 1966 and refers to a specific variety of ventricular tachycardia that exhibits distinct characteristics on the ECG torsade de pointes: ( tōr-sad' dĕ pwant' ), This word, referring not to individual QRS complexes but to an overall pattern of variation in their form, is properly used in the singular, not the plural ( torsades de pointes ). Twisting of the points, a form of ventricular tachycardia nearly always due to medications and characterized by a long.

Some psychotropic medications have been associated with prolongation of the QT interval and QT prolongation, especially in those with medical illness, and are linked to lethal ventricular arrhythmias, such as Torsades de Pointes (TdP). In 2013, we published a review of QT prolongation, TdP, and psychotropic medications A case is described of torsade de pointes in a 41 year old woman with pre-existing QTc prolongation, potentially exacerbated by treatment with sotalol. Previous cardiac investigations had been normal and after a second episode of ventricular fibrillation the patient was referred for electrophysiological studies. The authors review the physiology, causes, and treatment of QTc prolongation and. Introduction. Drug-induced torsades de pointes (TdP) is a potentially lethal ventricular arrhythmia that is associated with drugs that prolong the QT interval on the electrocardiogram (ECG) due to their interference with the cardiac potassium current, I KR.Intravenous (IV) formulations of methadone have been associated with TdP and contain the preservative chlorobutanol, which, like methadone.

Torsades de pointes may be self-limited or may progress to VENTRICULAR FIBRILLATION. A malignant form of polymorphic ventricular tachycardia that is characterized by HEART RATE between 200 and 250 beats per minute, and QRS complexes with changing amplitude and twisting of the points Characteristic Pattern of TdP. The term torsade de pointes was coined by Dessertenne in 1966 as a polymorphic ventricular tachycardia characterized by a pattern of twisting points. 1 Several ECG features are characteristic of TdP and are illustrated in Figure 1.First, a change in the amplitude and morphology (twisting) of the QRS complexes around the isoelectric line is a typical feature of. We report a patient with sotalol-induced torsades de pointes episodes that did not respond to magnesium and amiodarone. Electrical defibrillation totaling 15,120 joules had to be applied Torsades de Pointes (twisting of the points) is characterized by rapid, irregular QRS complexes twisting around the isoelectric baseline. Depending on the cause, TdP may either spontaneously revert back into sinus rhythm or degenerate into other life-threatening dysrhythmias

Torsades de pointes can be diagnosed by assessing an individual's calcium, magnesium, and potassium levels, but the best way to diagnose this condition is through an electrocardiogram (EKG). An EKG measures the electrical currents in the heart and displays them as waves (wavy lines) on a screen Examples of polymorphic ventricular tachycardia with long QT interval and short coupling interval pseudo-torsade de pointes and true torsade de pointes. In all traces, the QTc is shown in blue, the coupling interval of the beat starting the ventricular tachycardia in read, and the average ventricular rate during the first five beats of ventricular tachycardia in black In the long QT syndromes (LQTS), malfunction of ion channels impairs ventricular repolarisation and triggers a characteristic ventricular-tachyarrhythmia: torsade de pointes. Symptoms in the LQTS (syncope or cardiac arrest) are caused by this arrhythmia. In congenital LQTS, mutations in the genes encoding for ion chanels cause this channel malfunction Torsade de pointes is widely thought to be triggered by reactivation of calcium channels, reactivation of a delayed sodium current, or a decreased outward potassium current that results in early. Torsades de pointes are infrequent ventricular polymorphic tachycardias characterized by a typical twisting morphology, some very specific precipitating factors, and a specific treatment

Torsade de pointes with a long QT interval (QTc=680 ms) was observed on the 12 lead ECG in the emergency department and intensive care unit. A careful drug history revealed that sulpiride was the culprit agent. After stopping the medication, the QT interval returned to normal (420 ms) Rationale: Drug-induced prolongation of the corrected QT interval (QTc) may lead to serious and potentially life-threatening ventricular tachyarrhythmia, such as torsades de pointes (Tdp), which is worthy of clinical attention. Here, we report 1 case of Tdp after a coadministration of fluoxetine and amiodarone.. Patient concerns: A 62-year-old Chinese male who placed with the implanted. While torsades de pointes may be initiated by early afterdepolarisations (EADs) arising from Purkinje fibres and spreading to ventricular myocardium,1 acetylcholine may facilitate EADs by lengthening Purkinje fibre action potentials,4 whereas atropine should counteract EADs by shortening ventricular refractory periods.5 Indeed, acetylcholine injection caused QT prolongation and torsades de.
