Feasibility Of A New Non Invasive Method For The Evaluation Of Coronary Blood Flow In Coronaries: Transthoracic Convergent Color Doppler Mode Along With Pharmacologically Induced Heart Rate Lowering

We tested the hypothesis that transthoracic coronary blood flow Doppler recording with a sensitive Doppler mode such as convergent color mode (CC-Doppler TTE) can be further improved by lowering the heart rate (HR) down to <60 b/m, since low HR <60 b/m causes a disproportional lengthening of
