WPW Syndrome Types

WPW syndrome

In the disease pathway called WPW syndrome with (Wolf-Parkinson-White syndrome), and a bunch Kent is present, the bundle Kent, the right atrium - the left atrium or right ventricle - There are those present in the left ventricle, i

n rare cases in some casestoward the interventr

icular septum.
In the case of the right ventricle, to the right ventricle is excited at the early stage, the conduction of excitement, the right ventricle left ventricle becomes later in the destination,the ECG waveform is the type left bundle branch block - right atrium site is the presence of the bundle Kent indicate. On the other hand, the left atrium - If you want to exist between the left ventricle, left ventricle are excited for the early, the conduction ofexcitement, the left ventricle and right ventricle becomes late


r in the destination, right bundle branch block type ECG waveform for that indicate.
In addition to this feature, in the WPW syndrome, the waveform of the specific wavecalled delta (Δ) appears after the P wave of the electrocardiogram in the ventricle thatare excited at an early stage. This is part of the differences between bundle branch block. However, you may miss this delta wave, and do not look carefully, the ECGwaveform, the waveform monitor because it is difficult to determine, if in doubt be sure to record the

12-lead ECG in particular.
WPW syndrome is important and has been considered one of the causes of sudden cardiac death. This occurs, tachyarrhythmia fibr

illation or tachycardia, or flutter in the atrium, to cause ventricular fibrillation or ventricular tachycardia excitement frequentpasses through the bundle Kent, will be conducted to the ventricle as tachycardia (;ventricular tachycardia false pseud VT) is. For such cases, the treatment cut theaccessory pathway catheter ablation or by surgical procedure has been carried out.

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...
