Chapter 2903: 2703 We Won't Tell Her (Sect Leader Yuxin Bonus Chapter 1)

"How annoying." Xie Yiren said somewhat unhappily.

Seeing father and child leave, Zheng Ren smiled and patted Xie Yiren's head, saying, "Yeah, yeah, I'm annoyed too."

"Boss, if Yi Ren gets bullied, what are you going to do about it?" Su Yun asked from the side with ill intent.

"Don't talk nonsense, how could Yi Ren be bullied?" Zheng Ren brushed the question aside—anyone who could ask such a thing really deserves a beating—"I'm asking you..."

"Tch."

"With a family history, when the illness strikes depends on luck; maybe the kids' luck was really bad and they already died first—what disease are you considering?" Zheng Ren asked.

"Um... non-structural heart disease." Su Yun said, frowning.

"What is that?" Chang Yue asked.

"Zou Jia Hua, heart ion channel disease is a kind of non-structural heart disease." Zheng Ren said, "But if that old lady really had an illness, it would definitely be milder than Zou Jia Hua's; otherwise she wouldn't have lived to such an age."

"Huh? Chief Zheng, are you saying she's ill?" Chang Yue asked.

"Maybe, just idly analyzing." Zheng Ren walked out carrying the bag; leaving the mall felt refreshing, and he could even see his energy bar slowly rising.

"Agile limbs, no joint disease—that's the initial assessment." Zheng Ren spouted nonsense, "After snatching the child's money, they'd say thanks for helping grandma pick up money; when questioned, they'd immediately turn hostile, with logical steps—from a fraud perspective, the response is flawless, considering no senility."

"Saying all that useless stuff just means you're cowardly, venting by beating your wife and scolding your child behind their backs." Su Yun said disdainfully.

Zheng Ren spread his hands.

This guy's spirits are off; everyone knows that old lady is a big trouble—whoever gets involved with her suffers bad luck.

Zheng Ren felt that Su Yun had this tendency to vent, just not stated outright; he smiled and said, "Besides, from what she said we can infer it should be an elderly person sending off a younger one, so I think Su Yun is right."

"Speaking of this, I suddenly recall a disease." Su Yun changed expression faster than flipping a page, and immediately continued on Zheng Ren's topic: "Zou Jia Hua's heart ion channel disease belongs to the type whose gene encoding hasn't been detected yet; Brugada syndrome has a gene encoding, the condition isn't severe, and it's possible to live seventy or eighty years with ST segment changes and be fine."

Zheng Ren smiled; the Brugada syndrome Su Yun mentioned happened to be the diagnosis given by the system panel.

This time, Su Yun's guess was spot on.

"Did you also notice she had slight difficulty breathing when she spoke?" Zheng Ren asked.

"Um, I don't think the rise in tone in her last sentence was due to nervousness or emotional excitement; I consider it sudden shortness of breath. I hadn't thought much about it, assuming mild asthma or something similar. But if we go by what you said, the diagnosis would be Brugada syndrome."

"Diagnosis?" Chang Yue asked doubtfully.

"Brugada syndrome is a syndrome caused by mutations in the genes encoding cardiac muscle ion channels, leading to abnormal ion channel function."

"Clinically, this syndrome is characterized by ST-segment elevation in leads V1–V3, variable ST-segment in leads V1–V3, no obvious structural heart abnormality, polymorphic ventricular tachycardia or ventricular fibrillation, recurrent episodes of atrial fibrillation and syncope, and cardiac sudden death."

"Emotional agitation, sudden breathing difficulty, and slight lip discoloration already prove she has an underlying heart condition. But initially she was agile; we estimate she usually doesn't get sick often or her episodes are mild, so when she does fall ill she treats it as a weapon."

Zheng Ren began analyzing.

"Boss, you're just too dark!" Su Yun, unable to gesture because she was holding a plastic bag, retorted without hesitation.

"Chief Zheng, do you mean her symptoms are mild each time she gets sick, so she often uses this to extort money?" Chang Yue exclaimed.

"Well, if the analysis is correct, it could be like that." Zheng Ren said, "For example, triggers like emotional agitation can quickly relieve symptoms. By the way, when I worked in the emergency department I once encountered a patient with Adie's pupil who pretended to have a cerebral hemorrhage to extort money. At the time Manager Zhou didn't notice either; it was a gang fraud that almost succeeded."

"Adie's pupil is possible, what you're saying..." Su Yun pondered.

"That's also possible, so that drives a wedge between you. She herself said it, didn't she? 'Lonely old woman.' From that we can infer her children are probably dead..."

"No, she was just making a metaphor!" Su Yun corrected.

"I grabbed you and the child's father; did she then have no other movements?"

"Then what happened?"

"Who shouldn't you provoke? It's this sort of unreasonable old person who extorts with children. She snatched money from the child's hand to make the child's father go argue, then successfully extort. Having extorted a child and with mall surveillance footage, she couldn't actually get any money. Snatching three dollars is enough to do something."

"What you say sounds somewhat reasonable." Su Yun mused.

"It's not just somewhat reasonable; I think it's already very close to the truth." Zheng Ren stated the truth he saw on the panel, naturally full of confidence.

"You think this is a detective drama?"

"\"New England Journal\" has a report." Zheng Ren said, "An autosomal dominant hereditary disease, familial ST-segment depression syndrome."

"Multiple centers in Denmark, the Netherlands, and the UK collectively gathered five families, all showing similar features: ECG changes manifest as persistent, stable, significant non-ischemic ST-segment depression, slowly developing atrial fibrillation and ventricular arrhythmias, sometimes accompanied by mild left ventricular dysfunction, inherited in an autosomal dominant manner."

"Almost all conditions match, but I dare not definitively say it's that; however, such people are best avoided—they're trouble." Zheng Ren smiled, "You wouldn't actually think of bringing her food tomorrow, would you?"

Su Yun sighed, her mood a bit low. Everything her boss said was true; she felt he'd invented a disease to comfort himself. Still, his explanation was quite convincing—poor guy.

"Zheng Ren, how serious is this disease?" Xie Yiren asked.

"This disease early on has almost no abnormal symptoms, but it's deadly. With age, nearly all cases develop into atrial fibrillation–representing atrial arrhythmia, and even sudden ventricular tachycardia can occur, leading to sudden death." Zheng Ren said, "Specifically, it depends on fate."

"Can it be treated?"

"Yi Ren, you can't be a saint." Su Yun said disparagingly.

"Just like Zou Jia Hua, implanting a cardiac pacemaker would do." Zheng Ren said with a smile, "But we won't tell her."
