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),激动通过旁路预先激动心室而产生...
WPW综合征是心脏传导系统发育的一种变异，可能使心电图（ECG）出现特殊的波形，这些波形称为Delta波。Delta波是一种由预激细胞引起的波形，位于QRS波前面，表明激动从心脏前向传导。而正常的激动传导是经过心脏传导系统独立激发的。WPW综合征本身通常是无害的，但Delta波可以成为心脏快速搏动的起点，导致室...
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...
The current source is expected to be localized more exactly with a magnetocardiogram (MCG) than with an electrocardiogram (ECG). In the present study, the isomagnetic map at the time of the delta wave and a gated magnetic resonance imaging (MRI) were compared to assess the usefulness of ...
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 ...

•dizziness •light-headedness •fainting •shortness of breath Most people who have Wolff-Parkinson-White Syndrome are not troubled by symptoms unless their heart rate is over150beats per minute,at which point they will have heart palpitations.Causes of Wolff-Parkinson-White Syndrome This ...
The presence of accessory pathways is electrocardiographically manifested by a delta wave just before QRS initiation, leading to a short atrioventricular delay due to its uninhibited electrical conduction, and eventually to asynchronous contraction (8, 9). Radiofrequency catheter ablation (RFCA) treatment...
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...
By doing this, APs are eliminated, or their number is reduced, which in addition to treating WPW and removing the delta wave in the ECG by preventing AP from preventing induced AF. In those who do not have surgery, FLACAINID is used in combination with BISOPROLOL, which is an effective ...
