250 Bpm

For months now we've been visiting doctors and taking tests. The blond twin was diagnosed with SVT, a heart condition in which the heart rate elevates, but one chamber does not come back down. The blond twin's pediatric cardiologist said he most often sees it in infants and teenagers. She's the perfect age for it to start.
Medical professionals reviewed each of her tests with awe. They commented on how strong her heart was and how she was in such great shape. They wondered if she wasn't really just experiencing panic attacks.
I was not happy.
The blond twin was clearly having a medical emergency. It wasn't as easy as saying it was a panic attacks. We knew the trigger. We knew the outcome. We just couldn't replicate it during the tests so the medical professionals were unable to prove it was real.
The final test was the cardiac stress test. The blond twin ran on the treadmill, at the highest speed and the steepest incline, with ease. The cardiac therapist was checking her post-test vitals when she went into an SVT.
I was both terrified and elated. I realized as I was dealing with these conflicting that it was crazy. I was terrified because her BPM was 250. Her heart was pounding at 250 beats per minute. I was elated because she was still hooked up to the EKG machine. It was all recorded for every medical professional to analyze.
After a one block trip to the emergency department (via an ambulance despite being in an outpatient building connected to the hospital), we went home with a heart monitor, medication and recommendation for an ablation.
It was a long, exhausting day, but we finally had progress.
