↪ ECG Basics Homepage The PR segment is the flat, usually isoelectric segment between the end of the P wave and the start of the QRS complex. PR segment abnormalities These occur in two main conditions: Pericarditis Atrial ischaemia Pericarditis The characteristic changes of acute pericarditis are: PR segment depression. Widespread concave (‘saddle-shaped’) ST elevation. Reciprocal ST depression and PR elevation in aVR and V1 Absence of reciprocal ST depression elsewhere. NB. PR segment changes are relative to the baseline formed by the T-P segment. ...
