Unstable tachyarrhythmia is treated with synchronized cardioversion - initially 0.5-1 J/kg but can increase to 2 J/kg if smaller dose is not working. Stable tachyarrhythmia treatment is subcategorized based on narrow QRS vs. wide QRS. If narrow QRS/ SVT, perform vagal maneuvers and give adenosine.
The management of tachycardia depends on its type (wide complex versus narrow complex), whether or not the person is stable or unstable, and whether the instability is due to the tachycardia. [10] Unstable means that either important organ functions are affected or cardiac arrest is about to occur. [10]
Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...
T-wave alternans and prolonged QT interval in a male patient found to be in a narrow-complex tachycardia and ruled in for an acute myocardial infarction.Administered Ibutilide and converted to sinus rhythm but subsequently had an episode of Torsades de Pointes which required DC cardioversion back into sinus rhythm.
Advanced cardiac life support, advanced cardiovascular life support (ACLS) refers to a set of clinical guidelines established by the American Heart Association (AHA) for the urgent and emergent treatment of life-threatening cardiovascular conditions that will cause or have caused cardiac arrest, using advanced medical procedures, medications, and techniques.
Ventricular tachycardia is characterized by an altered QRS complex and a heart rate greater than 100 beats per minute. [62] When V-tach is sustained (lasts for at least 30 seconds), inadequate blood flow to heart tissue can lead to cardiac arrest.
Group of pharmaceuticals that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Type I (sodium channel blockers) Type Ia Ajmaline; Procainamide; Quinidine; Type Ib Lidocaine; Phenytoin; Type Ic Encainide; Flecainide; Propafenone; Type II (beta ...
Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia . It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [ 2 ]
