What does broad complex tachycardia mean?
What is broad complex tachycardia? A tachycardia is defined as a heart rate greater than 100 beats per minute (bpm). In broad complex tachycardias the QRS complex is longer than 120 ms (three small squares on the ECG).
What are 2 common cause of 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 wide complex tachycardia the same as V tach?
Ventricular tachycardia refers to a wide QRS complex heart rhythm — that is, a QRS duration beyond 120 milliseconds — originating in the ventricles at a rate of greater than 100 beats per minute.
How is VT diagnosed?
To diagnose VT, recording of the heart rhythm is required. Your healthcare provider may order an electrocardiogram (ECG). This test records your heart rate and rhythm. Your provider may want to closely watch your heart’s activity for a longer period of time using a Holter monitor or event recorder.
What rhythm is wide complex tachycardia?
Wide complex tachycardia is a cardiac rhythm with more than 100 ventricular beats per minute and a QRS complex of 120 ms or greater.
What does VF look like on an ECG?
It has an appearance on electrocardiography of irregular electrical activity with no discernable pattern. It may be described as ‘coarse’ or ‘fine’ depending on its amplitude, or as progressing from coarse to fine V-fib.
What drugs should be avoided with 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 rhythms are wide complex tachycardia?
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 heart rate is VT?
Ventricular tachycardia heartbeat This condition may also be called V-tach or VT. A healthy heart typically beats about 60 to 100 times a minute at rest. In ventricular tachycardia, the heart beats faster, usually 100 or more beats a minute.
Do you shock wide complex tachycardia?
With wide-complex polymorphic tachycardias, we have to defibrillate them, usually because it won’t sync up with that. With that wide, bizarre polymorphic rhythm, the machine may not sync up to that. We don’t want to delay defibrillation or providing electrical therapy to an unstable patient.
Why is VF a shockable rhythm?
Shockable Rhythm: VFib In VFib cases, the heart quivers ineffectively and as a result, no blood is pumped out. On an ECG monitor, VFib will look like a wavy, disorganized line. VFib can either be fine or coarse. Coarse VFib is more likely to convert after defibrillation than fine VFib.
What happens if you give adenosine in VT?
Adenosine is an efficacious diagnostic and therapeutic agent in the acute management of wide complex tachycardias. Its potent negative dromotropic effect terminates supraventricular tachycardias involving the atrioventricular node, allowing differentiation from tachycardias of atrial and ventricular origin.
Which beta blocker is best for tachycardia?
Arrhythmias: bisoprolol and metoprolol succinate are often preferred. Beta-blockers are the first-line treatment for long-term symptomatic rate control in patients with a range of cardiac arrhythmias, including atrial fibrillation and ventricular tachycardia.
Which drugs should be avoided in irregular wide complex tachycardia?
