Hello. My baby girl was born at 33weeks and ECG was done at the age of about 4 weeks. ECG showed QTc being between 440-460. Then they did a holter monitor that showed QTc between 410-480. Of course when it's a small baby we are talking about her heart rate is higher then that of an adult, so her heart rate varied from 70+ to 160 on her holter, average being about 130-140. Our doctors started beta blockers to her immediately. There is no history of LQTS on either my or the babys fathers families, and we both have a normal QTc on our ECGs. There is also no history of sudden deaths or anything like that.
If I understood correctly QTc is most accurate if the heart rate is near 70? What do you think about our situation? Is my girls QTc worrying and is the medication neccesary? I am thinking if we should see another doctor for a second opinion? Does anyone have any experience with long QTc on a small baby..?
Thanks in advance for answers and apologize if my english is not perfect, it's not my native. :-)
