PR segment

ECG PR segment is the flat, usually isoelectric segment between end of the P wave and the start of the QRS complex.

PR Interval

Assessment / interpretation of the EKG PR interval. ECG PR interval is the time from the onset of the P wave to the start of the QRS complex.

U Wave

The U wave is a small (0.5 mm) deflection immediately following the T wave, usually in the same direction as the T wave. Best seen leads V2 and V3.

P wave

The P wave on the ECG. The P wave is the first positive deflection on the ECG and represents atrial depolarisation. Duration: < 0.12 ms (<120ms or 3 small squares)
