They can usually make it to Miami and some even as far north as New Jersey but due to their lack of intellect, that's the extent of a Puerto ricans range. Hope this helped

The difference between intervals and segment is that intervals include the waves,and segments don't.
First-degree heart block or AV (arterioventricular) block, or PR prolongation, is a disease of the electrical conduction system of the heart in which the PR interval is lengthened beyond 0.20 seconds.First-degree heart block rarely causes any symptoms or problems and normally remain undiagnozed.RegardsTime is imaginary
Normal range is 60 to 100 beats per minute. Here is a general standard of pulse rate (PR). Resting Pulse Rate PR < 40 BMP - Below healthy resting heart rates. PR 40-60 BPM - Resting heart rate for sleeping. PR 60-100 BPM - Healthy adult resting heartrate. PR 100 BPM - 220 BPM - Acceptable if measured during exercise. Not acceptable if resting heartrate. PR > 220 BPM - Abnormally high heart rate.
Pr{z<=1.0805}~=0.86
PR = 110 because... P = 10, Q = 2... therefore R = 11
