Wolff-Parkinson-White (WPW) syndrome with PSVT.



Wolff-Parkinson-White (WPW) syndrome with PSVT.
Female 47 years old, with a shake of the EKG to see. After the second treatment is the idea that the reason for the shake of the EKG is the first of what And the treatment here?

Ecg 1


Ecg 2




The EKG is the first one with paroxysmal supraventricular tachycardia (PSVT).
After the treatment a second time for delivery. Wolff-Parkinson-White (WPW) syndrome.

Wolff-Parkinson-White (WPW) syndrome is a congenital anomaly.
This occurs because the electrical signal from atrium is transmitted to the ventricle through the accessory pathway (which is the accessory pathway is the Bundle of Kent or the Kent Bundle in WPW syndrome) and the AV node, but the signal will not be delayed in the accessory pathway that. electrical signal through the accessory pathway to the ventricle and stimulating. depolarization of the ventricle slowly (ventricular preexcitation) before the signal from the AV node to reach on the ECG is an important characteristic of the QRS complex, the larger the delta wave occurs because the electrical signal into the ventricle by accessory pathway does not. Purkinje fibers, making the signal more slowly, so the QRS complex is wider than normal. The main problem in patients with WPW syndrome is an electrical signal from the accessory pathway can also return to the atrium through the AV node and cause antidromic AV reentrant tachycardia in patients with this condition, heart rate, 150-250. per minute in patients with WPW may be fatal if cardiac arrhythmias and atrial fibrillation or flutter in conjunction with the adoption of the electrical signal from atrium to ventricle will not be delayed or accessory pathway to the electrical signals pass. ventricle and the rapid increase of the compression of the ventricle is very high throughout life threatening.
Treatment
- Patients with no symptoms will be evaluated periodically, Radiofrequency (RF) ablation as first-line treatment in patients with symptoms. The drug is used in the case of RF ablation have not been made or the patient refuses to do, and patients may have severe complications from the RF ablation.
- Drug Ic and class III antiarrhythmic. The slow down in the accessory pathway, which inhibits the occurrence of PSVT. But if the patient has a history of atrial fibrillation or atrial flutter was associated with AV nodal blocking drugs should be used.
- The digoxin is contraindicated in patients with WPW syndrome because of the WPW. death syndrome. Most are related to the use of digoxin.

Ventricular preexcitation and the Atrioventricular reentant tachycardia.

Wolff-Parkinson-White (WPW) Syndrome

Myself Atul kapoor from India Few days back i get tachycardia and my blood pressure was low it was 90/70 my brain singles me something wrong with my heart i went to M.d doctor he diagnosed me Wolff-Parkinson-White (WPW) Syndrome. iam going to tell everyone who needs info for wpw syndrome in future is it dangerous or not and what will happen and what will a man /women do in this cases iam going to put here my ECG AND ECO Report here. http://spermup.blogspot.com/ Wolff-Parkinson-White (WPW) Syndrome------Wolff-Parkinson-White syndrome is a disorder in which an extra electrical connection between the atria and the ventricles is present at birth. People may have episodes of a very rapid heartbeat. Most people have palpitations, and some feel weak or short of breath. Electrocardiography (ECG) is used to make the diagnosis.Usually, episodes can be stopped by maneuvers that stimulate the vagus nerve, which slows the heart rate. Wolff-Parkinson-White is written with hyphens because the syndr...

Wolff-Parkinson-White (WPW) syndrome Wolff-Parkinson-White (WPW) syndrome is a condition where the heart ventricles become pre-excited. In the normal heart beat, first the sinoatrial (SA) node signals the atria of the the heart to contract, This is then followed by the atrioventricular (AV) node signalling the heart ventricles to contract. The electrical signal for this contraction travels from the SA node to the AV node via the electrical pathway of the bundle of his. In Wolff-Parkinson-White (WPW) syndrome another additional electrical pathway called the bundle of Kent allows for electrical signals to travel from the SA to the AV node. This will result in ventricular pre-excitation (the ventricles may become over stimulated) and paroxyomal reentrant tachycardia (raised heart rate). The above white arrows shows the abnormal, additional electrical activity pathway to the ventricles through the bundle of kent. In Wolff-Parkinson-White syndrome the normal pathway of electrical activit...

Wolff-Parkinson-White syndrom(preexcitation syndrome; WPW)

On an ECG tracing, a delta wave is usually an unexpected finding. In the QRS complex, the Delta wave takes the place of the Q wave. In the graphic below you can see the difference between the tracing from normal sinus rhythm and a heartbeat tracing that includes a Delta wave. You may also notice that the PR segment (the portion of the tracing along the baseline, between the depolarization of the atria (P wave) and the beginning of the depolarization of the ventricles (QRS complex)) is missing. This happens because the electrical signal from the atria is being conducted to the ventricles immediately after atrial contraction, carried along an anomalous accessory pathway called the Bundle of Kent instead of through the AV node, which delays signal conduction to allow the ventricles to fill with blood before contraction. This produces Wolff Parkinson White (WPW) syndrome, which may be asymptomatic for a person’s entire life, but it also has the potential for initiating dangerous, rapi...
