What is the normal duration of a P Wave?

The normal duration of a P wave is indeed between 0.06 and 0.12 seconds. This duration reflects the time it takes for the atria to depolarize before contracting. The P wave is an important indicator of atrial function and is typically the first wave observed in the electrocardiogram (ECG) tracing. Measuring the duration of the P wave can provide insights into atrial enlargement or issues with conduction. A duration within the normal range implies that the electrical conduction through the atria is functioning effectively, supporting normal heart rhythm and function. Recognizing this parameter is critical for interpreting ECGs and diagnosing potential dysrhythmias.
