also should note her oxyen sat was 93 and she has also been diagnosed with asthma since around 4 months old.. (she is 2 and weighs 31 pounds)
A resting heart rate in the 140-180 range is certainly not normal, but not completely unexpected in the setting of WPW either.
The issue with WPW is that there is an accessory pathway between the upper chambers and lower chambers of the heart. Typically, there is only one connection between the two, and that is the AV node. In WPW, though, the extra pathway allows for extra communication between the top and bottom chambers, which provides an environment compatible with an SVT (supraventricular tachycardia).
Your daughter was likely in an SVT when all of this happened, which can cause the symptoms you were describing. The heart rate in SVT can be in the range of 150-200, sometimes even higher.
