What does WCT stand for medical?
A wide complex tachycardia (WCT) is simple enough to define: a cardiac rhythm with a rate >100 beats per minute and a QRS width >120 milliseconds (ms).
What is the treatment for wide complex tachycardia?
For a stable and regular wide-complex tachycardia, if ventricular, amiodarone 2 × 150 mg intravenously over 20–60 minutes is a safe treatment of choice. In previously known left ventricular fascicular ventricular tachycardia, verapamil and a beta-blocker are first-line options.
What is wide complex rhythm?
A wide complex tachycardia is defined as a rhythm disturbance with a rate greater than 100 beats/min and a QRS complex duration of 0.12 seconds or more in the adult patient.
What causes wide complex tachycardia?
Wide complex tachycardia is a dysrhythmia with a long list of potential causes that ranges from various arrhythmias, structural heart abnormalities, electrolyte disturbances, toxins, and many more.
Is atrial flutter a wide complex tachycardia?
The ECG shows a regular wide complex tachycardia with a left bundle-branch block configuration, northwest axis, and a negative concordance in precordial leads. High in the differential is atrial flutter, an arrhythmia often facilitated by flecainide.
Which drugs should be avoided in irregular wide complex tachycardia?
It is so very critical to choose the right kind of medication once the decision is made to treat a patient with wide complex tachycardia. Calcium channel blockers (Diltiazem and verapamil) are strongly advised not to be used for fear of hemodynamic collapse, hypotension and cardiac arrest [4].
What is the difference between SVT and VT?
Tachycardia can be categorized by the location from which it originates in the heart. Two types of tachycardia we commonly treat are: Supraventricular tachycardia (SVT) begins in the upper portion of the heart, usually the atria. Ventricular tachycardia (VT) begins in the heart’s lower chambers, the ventricles.
What is the heart rate in sinus tachycardia?
Normal sinus rhythm typically results in a heart rate of 60 to 100 beats per minute. Sometimes, these electrical impulses are sent out faster than normal, causing sinus tachycardia, which often results in a heart rate of over 100 beats per minute.
What is Lown Ganong Levine syndrome?
The Lown-Ganong-Levine (LGL) syndrome occurs when an accessory pathway is congenitally present that directly connects the atria to the ventricles, bypassing the AV node similar to the Wolff-Parkinson-White (WPW) syndrome.
What is a Pqrst complex?
An ECG complex consists of a PQRST complex. The sinoatrial node (SA) is the pacemaker of the heart and produces the P wave. The QRS wave is produced by the atrioventricular node (AV). The P wave in an ECG complex indicates atrial depolarization.
What drugs should be avoided in patients with irregular wide complex tachycardia?
Is SVT life-threatening?
Supraventricular tachycardia is generally not life-threatening unless you have heart damage or other heart problems. However, in extreme cases, an episode of SVT may cause unconsciousness or cardiac arrest.
