Therefore, the criteria for diagnosing LAE on a 12-lead ECG is as follows: The length of the P wave in lead II is greater than 120 milliseconds OR The downward deflection of the P wave in lead V1 ...

Because the electrical activation originates at or near the AV node, the P wave is frequently not seen; it can be buried within the QRS complex, slightly before the QRS complex or slightly after ...

5,6 It is possible that such cases of SCD could be avoided using electrocardiogram (ECG) for early detection of prolonged P-wave duration in these individuals, allowing for relevant intervention ...

A ventricular pacing stimulus occurs before each QRS complex (+). Prior to the ventricular paced complex there is a P wave; hence the mode of pacing is atrial-sensed ventricular-paced, or P-wave ...

There is no associated P wave, although an independent normal P ... sinus depolarization would suppress it 2,3. Figure 2: An ECG obtained from a beagle dog 21 days later, showing six rhythm ...

pathological Q-waves, left axis deviation and conduction delays and findings suggestive or diagnostic of primary electrical diseases such as long QT syndrome and Wolff-Parkinson-White syndrome. The ...
