Define the characteristics of atrial and ventricular arrhythmia.
Relate the ECG features to the relevant physiological processes
Develop reasoning skill that will enable you to explain some of the
less commonly observed ECG abnormalities
Identify potential pathways of care for the person presenting with a
variety of ECG changes.
Normal QRS: less than 3
small boxes ( less than 0.12
seconds), Narrow QRS.
Abnormal QRS: more than 3
small boxes (more than 0.12
seconds), Wide QRS.
Narrow QRS always.
Absent of P wave, or
Inverted P Wave, or
Present P Wave but PR Interval less than 3 small boxes (less than
Inverted P Wave comes after QRS.
Junctional Rhythm – Cont.
Absent Inverted PR Interval less
than 0.12 seconds
Inverted after QRS
Types of Junctional Rhythms
•Heart Rate 40 – 60 Beat per minute.
•Heart Rate 60 – 100 Beat per minute
•Heart Rate above 100 Beat per minute
