How do you read an ECG strip?
Heart rate can be easily calculated from the ECG strip: When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes. For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
What are normal readings on an ECG?
If the test is normal, it should show that your heart is beating at an even rate of 60 to 100 beats per minute. Many different heart conditions can show up on an ECG, including a fast, slow, or abnormal heart rhythm, a heart defect, coronary artery disease, heart valve disease, or an enlarged heart.
What is an abnormal ECG reading?
An abnormal EKG can mean many things. Sometimes an EKG abnormality is a normal variation of a heart’s rhythm, which does not affect your health. Other times, an abnormal EKG can signal a medical emergency, such as a myocardial infarction (heart attack) or a dangerous arrhythmia.
How do you read graph paper on ECG?
How to read ECG paper
- Each small square represents 0.04 seconds.
- Each large square represents 0.2 seconds.
- 5 large squares = 1 second.
- 300 large squares = 1 minute.
How does atrial fibrillation look like on ECG?
This means an ECG showing atrial fibrillation will have no visible P waves and an irregularly irregular QRS complex. The ventricular rate is frequently fast, unless the patient is on AV nodal blocking drugs such as beta-blockers or non-dihydropyridine calcium channel blockers.
How do you analyze an ECG?
- Step 1: Locate the P wave.
- Step 2: Establish the relationship between P waves and the QRS complex.
- Step 3: Analyze the QRS morphology.
- Step 4: Search for other clues.
- Step 5: Interpret the rhythm in the clinical setting.
What is a normal P QRS T axis?
Baseline ECG axes were automatically measured with normal values defined as follows: P-wave axis 0° to 75°, QRS axis -30° to 90°, and T axis 15° to 75°.
What does heart flutter look like on ECG?
Atrial flutter causes the heart to beat in a fast but regular pattern — unlike afib, which causes a fast and irregular pattern. Atrial flutter produces a distinctive “sawtooth” pattern on an electrocardiogram (EKG or ECG), a test used to monitor the heart and diagnose heart rhythm disorders.
What does ventricular tachycardia look like on ECG?
Other ECG features suggestive of VT include: Very broad complexes (>160ms) Absence of typical RBBB or LBBB morphology. Extreme axis deviation (“northwest axis”) AV dissociation (P and QRS complexes at different rates)

Width
How to read an EKG correctly?
Measure the time between your heartbeats. Locate the beginning of the P wave and the beginning of the QRS complex.
How to read EKG strips for Dummies?
– Rate is usually 60 to 100 bpm – PR intervals are prolonged for usually 0.20 seconds – QRS complex is usually normal – Rhythm is regular
How to read EKG strips made easy for nursing school?
– Correction of underlying cause. – Atropine for symptomatic slow rate – Pacemaker insertion if patient is refractory to drugs – Discontinuation of digoxin if appropriate.
