Objectives
- Explain each step in the EKG interpretation process.
- Using the rules of ECG Interpretation, identify sinus rhythms.
- Using the rules of ECG Interpretation, identify atrial rhythms.
- Using the rules of ECG Interpretation, identify junctional rhythms.
- Using the rules of ECG Interpretation, identify ventricular rhythms.
- Using the rules of ECG Interpretation, identify heart blocks.
- Using the rules of ECG Interpretation, identify cardiac arrest rhythms.
- Explain 12 lead EKG Interpretation.
Memorization vs. Interpretation
Rules of EKG Interpretation
5 Basic Steps
- Rate
- Is it Regular or Irregular?
- Is there a P wave Present?
- What is my PR Interval?
- How wide is my QRS complex?
Inherent Cardiac Rates
The frequency of impulse formation attributed to a given pacemaker location within the heart.
- sinus node, 60 to 100 beats/min
- atrioventricular junction, 40 to 60beats/min
- ventricle, 15 to 40 beats/min.
Rate: 300 rule
The square counting method is ideal for regular heart rates. Use the sequence 300-150-100-75-60-50-43-37. Count from the first QRS complex, the first thick line is 300, the next thick line 150 etc. Count the number of QRS complexes that fit into 3 seconds
Rate: ECG Rate Ruler
Regularity: Calipers
P Waves
- Are they present?
- Upright or Inverted?
- The P Wave represents Atrial Depolarization.
- Absence of a P wave indicates that there is no conduction witin the atria
- Absent or inverted P Waves with an associated narrow QRS complex may indicate a Junctional origin
PR Interval
In electrocardiography, the PR
interval is the period, measured in
milliseconds, that extends from the
beginning of the P wave (the onset
of atrial depolarization) until the
beginning of the QRS complex (the
onset of ventricular depolarization);
it is normally between 120
and 200ms in duration.
Abnormal PR Interval
