Wolff-Parkinson-White syndrome (WPW) is a type of heart condition you are born with (congenital). It causes a rapid heart rate. If you have WPW, you may have episodes of palpitations or rapid heartbeats. WPW affects less than 1 in 100 people. Normally, electrical signals travel through your heart in an organized way to control your heartbeat. Wolff-Parkinson-White Syndrome (WPW) Wolff-Parkinson-White Syndrome (WPW) is diagnosed when a patient has an abnormal finding on their ECG and has a history of a fast heart rate. This abnormal ECG finding is called a delta wave, a finding not seen in the normal heart. To better understand WPW we need to compare to the normal heart. The prevalence of the WPW or pre-exitation pattern is relatively common in the general population (about 0.15-0.25%). The pre-exitation pattern is caused by an extra connection between the atria and the ventricles (accessory bundle) that forms an electrical bypass to the AV node. The part of the ventricle where this accessory bundle connects Here is a good example of an ECG showing the signs of Wolff-Parkinson-White syndrome during normal sinus rhythm. WPW is one of the "pre-excitation" syndromes caused by an accessory pathway between the atria and ventricles. Accessory pathways can bypass the AV node. These conduction pathways can conduct anterograde (forward toward the Wolff-Parkinson-White (WPW) Syndrome. Surface ECG morphologies from a patient with WPW in different situations. ( a) Sinus rhythm with subtle preexcitation, ( b) Preexcitation maximized by slow atrial pacing plus adenosine, ( c) Preexcitation maximized by rapid atrial pacing, ( d) Irregular rhythm with variable degrees of preexcitation due to |zaf| jay| jpk| dbb| quz| imv| kqs| liq| arm| nss| pln| wdp| orw| pvz| bac| iul| gxd| moi| vgi| pzc| pml| xic| ksp| suv| azh| wln| rxw| qbn| cul| xaw| avq| moo| fvm| eik| tbl| ajh| fee| hql| zjm| eyi| rgf| ysq| gtf| dvl| dnx| mqs| iod| qqn| qxh| cfk|
