从６４７例门控心血池显像患者中选出各类心室相位图示空白区者４０２例进行分析，提示：（１）ＰＨ图右室流出道及中部空白区与年龄、性别及各类疾病无直接关系，可能是一种正常表现；（２）右室下部ＰＨ图空白区的产生与右室功能低下及右冠脉病变有关；（３）ＰＨ图空白区的存在能间接地反映心肌损害的程度；（４）左室ＰＨ图空白区的变化对判定患者病情的转归有重要的临床价值．
From 647 cases of gated patients with cardiovascular imaging were selected all kinds of ventricular phase map of 402 cases were analyzed, suggesting: (1) PH right ventricular outflow tract and the middle of the blank and age, gender and various diseases No direct relationship may be a normal performance; (2) the lower part of the right ventricle PH Figure blank area and right ventricular dysfunction and right coronary artery lesions; (3) PH map blank area indirectly reflect the existence of myocardial damage ; (4) The change of the left ventricular PH in blank area has important clinical value in judging the prognosis of patients.
