Narrow Complex Tachycardia Treatment
Narrow complex tachycardia treatment. Treat as for narrow complex Pre-excited AF consider amiodarone If VT or uncertain rhythm. Sotalol 100 mg 15 mgkg over 5 minutes. Adenosine is a purine nucleoside that administered intravenously causes transient complete AV node blockade.
Tachycardia With a Pulse Algorithm. In this case the regularity of the arrhythmia becomes important. Adenosine can be administered safely to all individuals with narrow complex tachycardia.
Furthermore the regular rhythms can be broken down into AV Nodal dependent and AV nodal independent rhythms which can help us remember the treatments as well. Tachycardia Procainamide IV Dose. There are three possible types.
Adenosine 6-12mg IV half dose if cardiac transplant or on dipryidamole. The treatment of tachycardia is based on the type of tachycardia. Class Ic antiarrhythmics flecainide or propafenone can be used.
Amiodarone 150 mg IV over 10 minutes OR. Amiodarone 300 mg IV over 20-60 min then 900 mg over 24 h If known to be SVT with bundle branch block. The one that I find the most useful is breaking them into regular and irregular rhythms.
Treat as for regular narrow-complex tachycardia Synchronised DC Shock Up to 3 attempts Amiodarone 300 mg IV over 10-20 min Repeat shock. Atrial flutter with a variable block rare. Safety of adenosine in treatment of tachycardia.
Atrial fibrillation affects about 25 per 1000 people paroxysmal supraventricular tachycardia 23 per 1000 Wolff-Parkinson-White syndrome 2 per 1000 and atrial flutter 08 per 1000. Adenosine remains the treatment of choice for terminating most types of regular narrow QRS complex tachycardias except those due to sinus tachycardia atrial tachycardia fibrillation or flutter.
Furthermore the regular rhythms can be broken down into AV Nodal dependent and AV nodal independent rhythms which can help us remember the treatments as well.
Avoid if prolonged QT or CHF. It may also be administered with care to persons with regular wide complex tachycardias if it is likely that the tachycardia is not a ventricular tachycardia. In stable patients adenosine is a very important tool in both treatment of certain SVTs and diagnosis. There are several different ways to break down the differential for narrow complex tachycardia. Narrow Complex Tachycardia which is further divided into Sinus Tachycardia and Supraventricular Tachycardia and Wide Complex Tachycardia possible Ventricular Tachycardia. Radiofrequency catheter ablation is an effective treatment for atrioventricular nodal reentrant tachycardia atrioventricular reentrant tachycardia Wolff-Parkinson-White syndrome and the permanent form of junctional reentrant tachycardia. It can also usually be used safely in asthmatics unless they have brittle severe asthma. Adenosine is safe in pregnancy. Adenosine 6-12mg IV half dose if cardiac transplant or on dipryidamole.
Adenosine can be administered safely to all individuals with narrow complex tachycardia. It is a useful diagnostic tool as well as a treatment in the setting of a narrow complex tachycardia. There are several different ways to break down the differential for narrow complex tachycardia. 2050 mgmin until arrhythmia suppressed hypotension ensues QRS duration increases 50 or maximum dose 17 mgkg given. There are three possible types. Narrow Complex Tachycardia which is further divided into Sinus Tachycardia and Supraventricular Tachycardia and Wide Complex Tachycardia possible Ventricular Tachycardia. Tachycardia can be classified as narrow complex QRS 009 sec or wide complex QRS 009 sec There are two algorithms used in the treatment of pediatric tachycardia.
