"WebYour healthcare provider can use an electrocardiogram (EKG/ECG) to diagnose left atrial enlargement. One of the signs of left atrial enlargement on an ECG is an unusual “P wave.” If you have this condition, the P wave that represents your atria contracting is longer than normal. It should be shorter than 120 milliseconds. " - Ekg with no p wave means
