An extended period of time between the P wave and the QRS complex on an ECG typically indicates a delay in the atrioventricular (AV) node, where the electrical signal from the atria is slowed before it passes to the ventricles. This does not indicate the atria are not contracting, nor does it directly relate to the speed of ventricular contraction.
