51例劳力型心绞痛患者和36例静息心绞痛患者,在连续2天内进行超声心动图潘生丁负荷试验(DET)各1次。试验前禁食至少3 h,停用一切药物。首先,在4min内静脉注入潘生丁0.56mg/kg(称小剂量);间隔4min以后,在2min内静脉注入潘生丁0.28mg/kg,总量达到0.84mg╱kg(称大剂量)。室壁节段活动分成:活动增强,活动正常,活动减弱和活动反常。给药后出现一过性心室收缩失调或者失调加重,判为DET阳性。 60例患者先后2次DET均为阳性,另27例患者先后2次DET均为阴性。41例患者先后2次DET均为小剂量潘生丁阳性,19例患者先后2次DET均为大剂量潘生丁阳性。38例DET阳性的劳力型心绞痛患者在先后2次DET中(开始给药至)心室收
Fifty-one patients with angina pectoris and 36 patients with resting angina pectoris underwent echocardiographic dipyridamole loading test (DET) once a day for two consecutive days. Fasting at least 3 h before the test, all drugs disabled. First, dipyridamole 0.56mg / kg (called a small dose) intravenously within 4min; after an interval of 4min, dipyridamole 0.28mg / kg intravenously within 2min, the total reached 0.84mg ╱ kg (said high dose). Segmental wall segment activity is divided into: increased activity, normal activity, activity and abnormal activity. After administration of a transient ventricular systolic dysfunction or imbalance, sentenced as DET positive. DET was positive in 2 of 60 patients, and negative in 2 of the other 27 patients. DET was positive for small doses of dipyridamole in 41 of the 41 patients, and twice as large of dipyridamole in 19 of the DET patients. 38 patients with DET-positive patients with labor-type angina twice in the DET (initial administration to) ventricular closure
