What does rimP 1 mean?
1. What is RIMP? RIMP stands for R ight V entricular I ndex of M yocardial P erformance and is an index of global RV performance. The value represents the relationship between the ejection and non-ejection time of the heart. The “non-ejection” times are the periods of time when all heart valves are closed.
What is the formula for calculating rimP?
RIMP is the non-ejection time (IVRT + IVCT) divided by the ejection time. To see this in a formula that would be: RIMP = (non-ejection time) / ejection time RIMP = (IVCT + IVRT) / ET
How do I perform rimP?
There are 2 methods to performing RIMP. One requires a two-step process that involves taking measurements from 2 different images and paying careful attention to R-R intervals. Yes….. I lost you already! We are not going to teach that method as we understand the reality of real-life scanning!
What are some of the limitations of Rimp?
The most obvious limitation of RIMP is obtaining a clear enough tissue Doppler reading to properly identify the non-ejection periods of the heart. As I was looking through everyday examples of right heart tissue Doppler it was hard to find images with clear enough wave forms to correctly identify the periods of IVRT/IVCT and therefore TCO.
