and researches the hardware design of the data acquisition system based on PCI local bus and DSP technique which realizes: 1) the conversion from analog signal to digital signal by the TLV1572 analog-to-digital converter;
Furthermore, a PCI-bus card which has the functions of timer, digital input,digital output ,D/A convertion is also designed. It meets the requirement of real-time control at hardwarelevel of the CNC system .
We design and construct a PCI-based high-speed real-time multi-function testing system with a capability of parallel acquiring 4 channel analog signals in 16-bit resolution at 20MHz sampling rate and store the data without data lost.
Detection of abnormal myocardial perfusion is crucial to the prognosis of patients with coronary artery disease (CAD) after they have undergone percutaneous coronary intervention (PCI).
The effect of myocardial reperfusion was evaluated using the above mentioned three methods 15 min after PCI.
For those patients with acute or total occlusion, the levels of myocardial perfusion before and after PCI were similar, as determined by IC-MCE and visually analyzed from 61 segments (P >amp;lt; 0.05).
Thus, the IC-MCE method is of great value to coronary artery disease (CAD) patients undergoing PCI, especially for those with acute myocardial infarction (AMI).
It is challenging to undo early percutaneous intervention (PCI) in the elderly with acute coronary syndrome (ACS).
