Is a prolonged PR interval dangerous?
Similarly, you may ask, what does a prolonged PR interval mean?
Duration. A long PR interval (of over 200 ms) indicates a slowing of conduction between the atria and ventricles, usually due to slow conduction through the atrioventricular node (AV node). This is known as first degree heart block.
Secondly, are short PR interval dangerous? When its length is lesser than 0.120 seconds, we speak as a short PR-interval. This event has a great capacity for severe cardiac arrhythmia production. Both entities can be very dangerous, separately. When they are together in the same individual, the consequences could be deadly.
Also question is, how long can a PR interval be?
The P-R Interval The first measurement is known as the "P-R interval" and is measured from the beginning of the upslope of the P wave to the beginning of the QRS wave. This measurement should be 0.12-0.20 seconds, or 3-5 small squares in duration.
Is 1st degree AV block dangerous?
In rare instances, a first-degree heart block may develop into a more serious type of heart block that results in slower heartbeats. This may cause symptoms.
