"You have tachycardia?" Tess asked, once Sam had calmed down a bit.
"Yes. Have done ever since I was a child." Sam said, holding her chest as if not to let it explode.
"It would have helped if you had told us." Zoe said.
"Yes but I wanted to help. If you had known then you wouldn't have let me help Kelsie." Sam sighed and winced as her chest hurt. Tess moved the oxygen mask back on her face but Sam pushed it off.
"You need it Sam." Tess said as she was sat by theside of the bed.
"No i'm fine." Sam said. Tess raised her eyebrows. "Let me talk, and i'll put it back on."
"Fine." Zoe said.
"Well, I've had tachycardia ever since I found it hard to breath and collapsed in primary school." Sam said and put the mask back on and took a few more breaths before taking it off. "Had countless ECGs and stress tests." Sam sighed. "I got fed up of them and stopped going. I guess this was coming to me." She shrugged and put the mask back on.
"When was the last time this happened?" Tess asked, and Sam moved the mask again.
"I don't know, maybe a few years ago. Ive had a few close scared because I always run, but it hasn't been like this." Sam put the mask back on and took some deep breaths before Zoe spoke.
"Your heart fate is slowly making its way back down..." Zoe said. "It was at around-"
"Three hundred beats a minute?" Sam asked lifting the mask. "Yeah I know. It does that."
"What normally causes your heart to beat that fast?" Tess asked. "I know what the symptoms are, i'm just asking what caused yours?"
"Mostly stress." Sam sighed.
"What stressed you out today?" Zoe asked.
"Everything. I didn't feel well but you needed my help." Sam shrugged. "I thought it was nothing."
"You should have stayed at home." Tess said.
"I didn't know this was going to happen." Sam sighed.
"Was it just that you didn't feel well?" Zoe asked softly. "Or was it what happened in resus earlier?" Zoe looked at the ECG and saw Sam's heart had sped up a little. Sam took some more breaths out of the oxygen mask.
"Take deep breaths Sam." Tess said, watching as Sam took off the mask to glare at her.
"I know what to do." Sam said. "And Zoe, you got it right."
"What happened earlier?" Tess asked as Sam went to speak.
"No, let me explain." Zoe said, watching Sam. "There was a young girl in resus earlier, about seven years of age, had severe blunt head injury. There wasn't anything we could have done.

A tear slipped down Sams face as Zoe explained. The monitors beeped to show Sams heart rate increasing again.
"Keep taking deep breaths." Tess said as Sam seemed to panic. "Don't worry."

They continued to monitor the ECG while Sams breathing started to improve again.
"Thats it Sam." Tess said to comfort Sam. Soon enough, her breathing returned next to normal.
"So now that we know you have tachycardia, we know what to look for." Zoe raised an eyebrow at Sam and she rolled her eyes in return.
"Yes." Sam said. "But this won't keep me out of resus."
"No." Zoe shook her head. "But if I see any signs of this, you are going to be checked over, okay?"
"Fine." Sam huffed.
"Now rest for a little while." Zoe said. "I suspect you are tired after your little episode."
"Just a little." Sam said, still breathing oxygen from the mask.
"Then get some rest and I will check on you in a little while." Zoe smiled before Tess and her left the room.

"How is she?" Tom asked as they walked out.
"She's fine. Just resting." Tess said, putting her hand on his arm to comfort him as he was clearly worried.
"Tachycardia?" Tom guessed and Zoe spun around and nodded.
"How did you know?" Zoe asked.
"She showed most signs for it a minute ago." Tom shrugged.
"Gosh..." Zoe said, running her hands through her hair. "I probably should have noticed and stopped it." She looked guilty.
"You were busy Zoe." Tom said, watching Sam fall asleep.
"I could have stopped this." She said.
"Zoe, it was probably inevitable with the condition of the ED today. Don't blame yourself." Tom smiled and Zoe couldn't help but smile.
"I guess so." Zoe sighed. "Thanks."
"For what?"
"Cheering me up." Zoe said, before walking away, and Tom returned his attention to Sam.

(Thats it! Just a quick story that came to me.)
