γγOn the night shift on March 22, 2012, an 8-year-old girl was admitted to the cardiology ward with “malaise with vomiting for 8 days”. On admission, the child’s psychiatric examination and ECG monitoring showed that her heart rate was 193 beats/min and she was suffering from supraventricular tachycardia. The child’s cardiac enzymes and troponin increased significantly in Shenzhen North University Hospital. Myocardial injury was considered, and it was difficult to select antiarrhythmic drugs. I talked to the child while pressing the right orbit of the child, and the child did not respond to the pressure for about 10 seconds, then I pressed the left orbit of the child, and after 5 seconds the child’s heart rhythm changed to sinus, 100 beats/min. At the same time, the child complained of chest pain, which was relieved after about 3 minutes.γγI have been working in cardiology for nearly 10 years, but this is the first time I encountered such a case.
