Yes, 3 seconds is quite a long time if it is happening more than just once. It seems you mentioned in another thread that the cardio told you that you had pauses "up to" 3 seconds. How many pauses and do they match the timing of the lightheadedness? I would say most likely they do!

You should discuss in detail with your cardio the possibility of getting a pace maker if this problem is not short lived.
