MRI “triggering” operates to drive a digital channel of data. This data is collected along with other physiological signals. There are two ways to trigger the MRI.
There is no software processing involved and no associated delays. The digital trigger product pages contain more setup information to send a trigger based on the following physiological signals: ECG R-wave, blood pressure, respiration, and/or integrated EMG.
Note that when setting up the trigger in AcqKnowledge 5 or above, analog channels must be set first in order to see the channel listing (analog) in the Trigger drop down.
Delays could be introduced because performance will depend on the specifications of the computer you are using as well as the current processing load on that computer.
See application note AS191 for details.
Learn a technique—Trans-radial Electrical Bioimpedance Velocimetry (TREV)—that is more user-friendly and less invasive than the transthoracic method. TREV measures blood movement in the radial and ulnar arteries of the forearm via bioimpedance.
Topics Covered:
– Presentation and discussion of TREV
– Derived Indices Relevant to TREV
– Hardware setup
– Participant setup
– Recognizing good quality and bad quality data
– Demonstration with the grip anticipation test
– Review of results from other tests

Exercise physiology is the study of the body’s response to physical activity. Research in exercise physiology allows for insights in health and for a better understanding of the functions of the body at work. Here are some recent studies in exercise physiology that utilized BIOPAC tools for their research… Effect of exercise on electrocardiographic parameters […]
