Wolff-Parkinson-White syndrome 2. WPW的心电图特征: P-Rinterval<120ms Normal P wave vector(to exclude junctional rhythm) Presence of a delta wave QRS duration>100ms 3.心电图改变的机制: 除正常房室结径路( 正路) 外,还存有附加房室旁路(旁路)...
So on an ECG, people with WPW have a short PR interval with a delta wave as well as QRS prolongation, which makes sense because the signal’s taking the shortcut and contracting the ventricles early, which means the PR’s shorter and overall QRS complex is longer. 所以我们从心电图上来看...
Wolff-Parkinson-White syndrome (WPW) is characteristically diagnosed by the presence of a short PR interval, a delta wave, and a wide QRS wave on the surface ECG. In the absence of these clear criteria, absent septal Q waves have been used as additional evidence suggestive of subtle pre...

Ventricular preexcitation manifests on the 12-lead ECG with a short PR interval and a delta wave at the origin of the QRS complex.5 When this feature is associated with cardiac symptoms such as palpitations, syncope, or arrhythmias, it is referred to as Wolff-Parkinson-White syndrome. Show ...
The typical ECG finding of WPW is a short PR interval and a “delta wave.“ A delta wave is slurring of the upstroke of the QRS complex. This occurs because the action potential from the sinoatrial node is able to conduct to the ventricles very quickly through the accessory pathway, a...
In WPW, the delta wave is a sign of a bypass (AP), and APs are observed to be less common in children and adolescents aged 8-17 years than in adults [52]. In both symptomatic and asymptomatic groups, it was observed that in the group that did not perform RFA, in 1.5% of ...

That is a short PR interval and a delta wave, which is often an incidental finding during a routine ECG check. Commonly it is detected by a cardiologist when a patient is referred with palpitations, such as your mother’s case was. The ideal treatment in patients with symptoms is to ...
