-!Characteristics of a normal ECG
-|-
-|
-* '''[[Rhythm]]''': [[Sinus node rhythms and arrhythmias|sinus]]
-* '''[[Rate]]''': 60-100 bpm
-* '''[[Conduction]]''':
-** [[Conduction#The PQ interval|PQ interval]] 120-200ms
-** [[Conduction#The QRS interval|QRS width]] 60-100ms
-** [[Conduction#The QT interval|QTc interval]] 390-450ms (use the [[QTc calculator]] for this)
-* '''[[Heart axis]]''': between -30 and +90 degrees
-* '''[[P wave morphology]]''':
-** The maximal height of the P wave is 2.5 mm in leads II and / or III
-** The p wave is positive in II and AVF, and biphasic in V1
-** The p wave duration is usually shorter than 0.12 seconds
-* '''[[QRS morphology]]''':
-**No [[Q waves|pathological Q waves]]
-**No left or right ventricular [[hypertrophy]]
-**No [[microvoltage]]
-**Normal R wave propagation. (R waves increase in amplitude from V1-V5)
-* '''[[ST morphology]]'''
-**No [[ST morphology|ST elevation or depression]]
-**T waves should be [[ST morphology|concordant with the QRS complex]]
-* The ECG should not have changed from the previous ECG
