Patient S.O., a 5-year-old boy. Five congenital heart defects, including VSD and ASD. Moderate physical activity leads to peripheral and central cyanosis. Surgical intervention was proposed, even with the prospect of temporary and limited improvement, but the parents refused. Currently, complaints include chronic cough, mostly accompanied by vomiting. Vomit attacks occur no less than 10 times a day. Whenever the child goes out, parents always carry a plastic bag because he might cough and vomit, especially after eating. The family approached the clinic to have the boy undergo a course of resonant IR therapy. Significant improvement was not expected due to structural defects, but the parents decided to try. The treatment mainly involved the use of RV, RC, GI, and ZB emitters on the chest and heart area.
