If a patient's ECG reveals

If a patient’s ECG reveals an abnormally long delay between the P wave and the QRS deflection,
what does this suggest?

If a patient’s ECG reveals an abnormally long delay between P wave and the QRS deflection, it suggest that there is a delay of conduction from the atria to the ventricles. Hence, the stimulation from SA nodes are conducting stimuli to the ventricles very slowly.
