The RR interval in an EKG reading represents the time between two consecutive heartbeats. It is significant because it helps to assess the heart's rhythm and can indicate abnormalities such as arrhythmias or heart rate variability. Monitoring the RR interval can provide important information about the overall health of the heart.
rr means race replica
Hubbub, uproar.
Close to normal, but not quite.
RR in a postal address can mean rural route
No, Rr represents heterozygous genotype as there are two different alleles (R and r) present. For a genotype to be homozygous, both alleles must be the same (RR or rr).
In this context, "rr" typically stands for "race replica," indicating that the product is a replica of a vehicle used in racing, with high-performance features and design elements inspired by racing models. So, "Fireblade RR" would refer to a model of a motorcycle that is a race replica of a high-performance racing bike in the Fireblade series.

If you mean "better at doing EKGs", probably the EKG technician. If you mean "better at doing pharmacy work", most likely the pharmacy technician.
ECG and EKG mean the same thing, and it records the hearts electrical activity on a 6 second strip. The physician can make a diagnosis by looking at the EKG print out. If a 12-Lead EKG is used, then all walls and function of the heart will be recorded.
rr
An RR interval is represented in milliseconds. Thus, to report the RR interval in seconds, simplay divide the value by 1000. e.g. RR interval of 876 divide by 1000 = 876/1000 = 0.876
