If the heart rate does not return to normal with medical treatment, doctors may use a type of therapy called electrical cardioversion (shock). The long-term treatment for WPW syndrome is very often catheter ablation.
How is tachycardia treated in WPW?
It should be treated in the same way as AV nodal reentrant tachycardia (AVNRT), by blocking AV node conduction with (1) vagal maneuvers (eg, Valsalva maneuver, carotid sinus massage, splashing cold water or ice water on the face), (2) IV adenosine 6-12 mg via a large-bore line (the drug has a very short half-life) in …
Can you Cardiovert WPW?
Defibrillation pads are placed on the patient, and the decision is made to electrically cardiovert. A post-cardioversion ECG confirms the suspected diagnosis of AF with Wolff-Parkinson-White (WPW) (Figure 2).
What happens if you give adenosine to WPW?
Adenosine slows conduction time through the AV node. It can interrupt atrioventricular reentrant tachycardia (AVRT) by blocking conduction in the AV node to restore normal sinus rhythm in paroxysmal supraventricular tachycardia (PSVT), including PSVT associated with WPW syndrome.
What is heart shock treatment?
Cardioversion is a medical procedure that restores a normal heart rhythm in people with certain types of abnormal heartbeats (arrhythmias). Cardioversion is usually done by sending electric shocks to your heart through electrodes placed on your chest.
What medications should not be taken with WPW?
In particular, avoid adenosine, diltiazem, verapamil, and other calcium-channel blockers and beta-blockers. They can exacerbate the syndrome by blocking the heart’s normal electrical pathway and facilitating antegrade conduction via the accessory pathway [2, 5].
Why is Cardizem contraindicated in WPW?
Diltiazem should be avoided in the presence of pre-excited AF with RVR, that is, AF in the presence of accessory pathway, i.e. Wolff Parkinson White (WPW) syndrome, as AVN blockage can lead to increased conduction through the accessory pathway, leading to life-threatening rapid ventricular rates.
Why is amiodarone contraindicated in WPW?
Because amiodarone is a unique multichannel blocker, it potentially affects the atrioventricular nodal conduction rather than the accessory pathway conduction; therefore, the current guidelines do not recommend its use.
What drugs should be avoided in WPW?
When should adenosine not be used?
Patients with irregular heart rates, especially atrial fibrillation, patients with PSVT mimics such as atrial flutter with 2:1 conduction or sinus tachycardia in a dehydrated or stressed patient should never receive adenosine. Adenosine should never be used in wide irregular tachycardias.
What happens if adenosine doesnt work?
If adenosine does not work, atrioventricular (AV) nodal blocking agents like calcium channel blockers or beta-blockers should be used, as most patients who present with PSVT have AV nodal reentrant tachycardia (AVNRT) or AV reentrant tachycardia (AVRT).
What are the side effects of having your heart shocked?
Some other risks are:
- Problems breathing if you had medicine (sedation) to help you sleep during the procedure.
- Other less dangerous abnormal rhythms.
- Slow heart rate afterwards.
- Temporary low blood pressure.
- Heart damage (usually temporary and without symptoms)
- Heart failure.
- Skin damage/irritation.
What is the long-term treatment for WPW syndrome?
The long-term treatment for WPW syndrome is very often catheter ablation. This procedure involves inserting a tube (catheter) into a vein through a small cut near the groin up to the heart area. This procedure involves inserting a tube (catheter) into a vein through a small cut near the groin up to the heart area.
What causes supraventricular tachycardia in WPW syndrome?
In people with WPW syndrome, some of the heart’s electrical signals go down an extra pathway. This may cause a very rapid heart rate called supraventricular tachycardia.
How do you treat WPW syndrome with a catheter?
Thin, flexible tubes (catheters) are threaded through blood vessels to your heart. Electrodes at the catheter tips are heated to destroy (ablate) the extra electrical pathway causing your condition. Radiofrequency ablation permanently corrects the heart-rhythm problems in most people with WPW syndrome.
How often do people with WPW syndrome have rapid heart rate?
Some people with WPW syndrome have only a few episodes of rapid heart rate. Others may have the rapid heart rate once or twice a week or more. Also, there may be no symptoms at all, so that condition is found when a heart test is done for another reason.
