Because the atrial rate is so fast, and the action potentials produced are of such low amplitude, P waves will not be seen on the ECG in patients with atrial fibrillation. At times, the P wave ...

The waves on an ECG include the P wave, Q wave, R wave, S wave, T wave and U wave. Interval: The time between two specific ECG events. The intervals commonly measured on an ECG include the PR ...

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 ...

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 ...
