胚胎自第2周形成原始的心管开始,至最終发育成为完整的心脏,中間經历許多复杂的轉变过程,不論任何內在(如遺传)或外在(如风疹)因素,对此轉变过程的某一时期均可发生影响,造成发育停頓或障碍,致使心脏发生畸形,称为先天性心脏病。发病率約占初生儿的0.3％;占成人各种心脏病的1％。 The embryo begins with the formation of the primitive cardiomyocytes from the second week until it finally develops into a complete heart, with many complex transitions going through it, irrespective of any intrinsic (such as genetic) or extrinsic (such as rubella) factors Change the course of a period of time can have an impact, resulting in the development of pause or disorder, resulting in deformity of the heart, known as congenital heart disease. The incidence rate of about 0.3% of newborns; adult heart disease accounted for 1%.
