WebIn adults the normal PR interval is 0.12 to 0.20 second. 22 It is generally shorter in children and longer in older persons. The relation between heart rate and the duration of the PR interval is discussed in Chapter 19. The interval should be measured in the lead with the largest, widest P wave and the longest QRS duration.
WebShort QT syndrome (SQTS) is an extremely rare genetic disorder that causes an irregular heart rhythm. In SQTS, your heart muscle doesn’t take as long as usual to recover between beats. The part of your heartbeat called the QT interval is irregularly short. SQTS can cause arrhythmias in which you may feel dizziness, fainting or heart palpitations. safeway tofuWebThe PR interval on resting 12 lead ECGs in children varies mainly in relation to heart rate and is therefore usually shorter in younger children.
