Hello, my name is Adalynne and I am 11 years old. This past May, my chest started hurting and my heart was racing while swimming with my sister and grandmother. That evening my Dad came home and happened to check my heart rate with a pulse ox device that showed my heart rate was 240 beats per minute! My Dad called my Mom, who is a NICU nurse, and she told us that I was in SVTs, or Supra Ventricular Tachycardia(SVTs) and we needed to go to the ER. Once we arrived at the ER, the doctors and nurses quickly got me into a room, put a IV in my hand, and hooked me up to all kinds of machines. My Mom came down from the NICU, where she was working that day, and the Doctors were telling my parents that they would have to give me a medication to slow my heart rate down. Adenosine is a drug that “resets” your heart rate. They moved me into a different room where the crash cart was located and they put special leads on my chest that can shock my heart if it was needed. I had very kind nurses who were talking to me while all of this was happening, trying to distract me from the chaos. After they gave me the medication called Adenosine, my heart rate slowed down to around 100 beats per minute. They took multiple EKGs of my heart rhythm before and after the medication, drew labs and took an X ray of my chest. The next day we came to the Cardiac clinic and met with my new cardiologist. She told us that I have Wolff Parkinson White Syndrome, a condition that affects only 1 of every 10,000 people worldwide. She told us that I had been born with it, and that it is likely I will continue to have more episodes until I have an ablation when I am older. WPW is when there is an accessory pathway somewhere in your heart (that should not be there), and the electrical impulses go through this pathway triggering my heart rate to elevate to a dangerous rate. I was in SVTs for over four hours before I received the medication to slow my heart rate down. My Cardiologist taught us how to attempt "Vagal" maneuvers to slow the heart rate down, but also gave us a "Pill in the pocket(Attenolol)" to take if the vagals did not work in future episodes. She told us that if the Attenolol does not work to slow my heart rate down, then I would need to go back to the ER. Eight months later, I was at gymnastics conditioning for an upcoming Gymnastics meet.  I started to have chest pain and did a spot check of my heart rate, and it showed my heart rate was 230-240s. I think it was easier to stay calm this time since I knew what to expect, although I was scared of going to the ER again. I tried performing the Vagal maneuvers but I was not able to get my heart rate below 200. I ended up taking my Atenolol which brought my heart rate down to normal within the hour! I am raising awareness for WPW because not many people know what this diagnosis is. My cardiologist told us that I should live a totally normal life, but know what to do when a SVT episode happens.
