WPW syndrome: information, treatment and treatment



The WPW syndrome (Wolff-Parkinson-White syndrome) is a very specific heart rhythm disorder that is characterized by rapid heartbeat (tachycardia). The syndrome affects more men than women and occurs most often between 20 and 30 Age, whereby the frequency of the disease decreases with age.

Normally, the excitation of the heart muscle begins in the so-called sinus node. The electrical impulses spread through the atria from the first, fill with blood, while the chambers of the blood with which they are still placed in the arteries of the heart pumps away (diastole of the atria, systole of the chambers). As the momentum continues to spread the atria, the blood passed to the next chambers (atrial systole, diastole of the chambers). The impulses then reach the AV node slows the impulse briefly to allow the chambers to fill with blood. Shortly after, she then spread rapidly but in the heart chambers, leading to the chambers that pump blood into the arteries (systole of the chambers). The whole thing is a cycle that overlaps.

Causes

The WPW syndrome is happening now is that a short circuit is formed in the electrical impulse conduction of the heart. Here the pulses are not routed through the sinus node and AV node to the ventricles, but the AV node will be skipped so that the pulses are passed on much too early in the cardiac chambers. The ventricles are so excited too early (Präexitation) and pump blood out early in the arteries. Result is then a rapid heartbeat.
This short line is called Kent bundles.

Symptoms and Diagnosis

The symptoms can be used very suddenly. The victims then notice a rapid heart beat with a pulse of 180 beats per minute. Often it occurs also dizziness, rarely unconsciousness. In general, the heartbeat sets just as suddenly as it came. Very rarely can lead to ventricular tachycardia, which can be very dangerous. When symptoms occur frequently and severely impact quality of life, the patient should undergo treatment.

The doctor will usually already close by the typical symptoms of this arrhythmia. Then he is to confirm the diagnosis, can do an electrocardiogram. To characteristic changes are observed, indicating a WPW syndrome and the short circuit. Often, an electrophysiological study is required. This is a heart catheterization in which a type ECG is derived directly from the heart muscle, so to speak.

Therapy

Since arrhythmias are often short-lived they may be interrupted by so-called Vagusreize. These stimuli can be learned for example the straining at stool, drinking cold water, or immersing the face in cold water. During the attack can also be injected medication into the veins. If the tachycardia is often a permanent medical treatment necessary. In the worst case, a catheter ablation, which is a division of certain muscles in the heart to interrupt the short circuit, are performed. The success rate of 95% and is performed primarily in patients with atrial fibrillation.

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...

Bundle of kent

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...
