Thus, the results of the test occlusion can judge the state of endothelial function in small resistance
arteries (occlusion index) and large muscle (phase shift).
4.3 Pharmacological Test
Pharmacological test is designed to monitor and analyze the impact of pharmacological stimuli (this
term is used broadly to indicate any stimuli, such as pharmaceuticals, dietary supplements, emotional
stimuli, etc.) on the cardiovascular system (CVS).
During the test, the pulse waves are recorded and analysed continuously. The operator is able to assess
and compare the state of the patient's CVS before, during and after a pharmacological stimuli.
A typical test procedure involves collecting baseline pulse wave data before a stimulus. Once a sufficient
number of baseline pulse waves has been collected, the Angioscan software prompts the operator to
administer a stimulus. After the stimulus has been delivered, the pulse wave data is collected
continuously to assess the effect of the stimulus.
The post-stimulus recording time depends on the type of stimulus. For instance, a test with nitroglycerol
will require at least 10 min of data recording to capture the effects of the drug.
The length of analyzed baseline and the post-stimulus data collection periods can be adjusted after the
test.
The duration of the test, the type of stimulus and other parameters of the test are determined by the
operator. Hence, all the essential information about the test should be saved in the test description
(notes) in the patient database.
After the test, the operator can perform a detailed analysis of any portion of the recorded data.
Below is an example of data collected during a pharmacological test with nitroglycerin. After one minute
of baseline recording, nitroglycerin was administered and then the pulse wave data was collected to
