| Abstract | 「I. 緒言」心電図R波同期心プールシンチグラフィは種々の疾患における心機能評価に有用な検査法であるが, 数百心拍を加算してイメージを作成するため心房細動のような心拍数の変動が大きい症例では拡張期を正確に同期することが難しく弱点の一つであった. 今回われわれは心音II音同期装置を開発しそれを用いてR波II音同期心プールシンチグラフィを行い, その精度をファントム実験で検討し心房細動例への応用の可能性について述べた. 「II. 対象および方法」「1. R波II音同期プールシンチグラフィ」99mTc HSA 20mCi静注後, ガンマカメラとオンライン接続したコンピューターシステムを使用しフレームモードでデータ収集した. R波II音同期はポリグラフに今回開発したII音検出ユニットを組み込み使用した. |

| Abstract | [Summary] Anew method was devised for assessing cardiac function in patients with atrial fibrillation (Af) . Ejection fraction (EF) was calculated by the summation counts during 1,500 heart beats in each 10 msec. interval at both end-diastole and end-systole by means of electrocardiographic R wave and second heart sound gated method. To determine the reliability of the summation counts in patients with Af, phantom study was performed on the basis of the left ventricular volume measured by echocardiography. EF calculated by using mean end-diastolic and end-systolic volume was also in close agreement with mean EF in echocardiography. In conclusion, it was suggested that the EF measured by this method was reliable even in patients with Af. |
