How do you read a Step 1 EKG?
The ground rule always start reading an EKG by looking at Rito. Lead 2 will give you the best general view of the EKG. Step 1 check the p-waves. So what is the p-wave.

What does V1 show on ECG?
The precordial, or chest leads, (V1,V2,V3,V4,V5 and V6) ‘observe’ the depolarization wave in the frontal plane. Example: V1 is close to the right ventricle and the right atrium. Signals in these areas of the heart have the largest signal in this lead. V6 is the closest to the lateral wall of the left ventricle.
What does V1 and V2 represent ECG?
The areas represented on the ECG are summarized below: V1, V2 = RV. V3, V4 = septum. V5, V6 = L side of the heart. Lead I = L side of the heart.
What is a normal QRS?
The normal duration (interval) of the QRS complex is between 0.08 and 0.10 seconds — that is, 80 and 100 milliseconds. When the duration is between 0.10 and 0.12 seconds, it is intermediate or slightly prolonged. A QRS duration of greater than 0.12 seconds is considered abnormal.
What are normal EKG results?
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 are the 7 steps to interpret an ECG?

What are normal EKG readings?
What does lead 1 represent?
They are summarized as follows: Lead I: Right arm-negative, Left arm-positive. Records electrical differences between the left and right arm electrodes. Lead II: Right arm-negative, Left leg-positive.
Where do V1 and V2 go?
The proper location of V1 and V2 have not changed in many decades. They are located in the 4th intercostal space, just right and left, respectively, of the sternum. It is fairly easy to determine this spot using the angle of Louis as a landmark.
Where do you put V1 and V2?
The proper location of V1 and V2 have not changed in many decades. They are located in the 4th intercostal space, just right and left, respectively, of the sternum.
What is an abnormal EKG?
Defects or abnormalities in the heart’s shape and size: An abnormal EKG can signal that one or more aspects of the heart’s walls are larger than another. This can signal that the heart is working harder than normal to pump blood.
Does an EKG show blockage?
An ECG Can Recognize the Signs of Blocked Arteries.
Unfortunately, the accuracy of diagnosing blocked arteries further from the heart when using an ECG decrease, so your cardiologist may recommend an ultrasound, which is a non-invasive test, like a carotid ultrasound, to check for blockages in the extremities or neck.
What’s an abnormal EKG?
What are the most common ECG abnormalities?
Criteria for major prevalent ECG abnormalities were any of the following: (1) atrial fibrillation or atrial flutter (Novacode 1.5); (2) high-degree atrioventricular dissociation (Novacode 2.3. 1 and 2.3. 2); (3) left bundle-branch block (Novacode 3.1. 0 and 3.1.
What are the 8 steps needed to analyze an EKG?
Match
- evaluate the P wave. -is it present.
- Evaluate atrial rhythm. -regular.
- Determine the atrial rate.
- PR interval.
- evaluate the ventricular rhythm.
- determine the ventricular rate.
- calculate the duration of the QRS complex.
- calculate the duration of the QT interval.
What are the 6 steps to interpret an ECG?
The 6-Step Method How to Interpret Electrocardiogram Results
- Identify and examine the P wave. A normal P wave is present and upright.
- Measure the PR interval. The PR interval or PRI should be 0.12 – 0.20 seconds.
- Measure the QRS complex.
- Identify the rhythm.
- Determine the heart rate.
- Interpret the strip.
How do you know if an ECG is normal or abnormal?
The signals with heart rates outside the range of 60–100 beats per minute and QRS durations outside the range of 0.08 sec to 0.12 sec are considered as abnormal signals. The ECG signals with heart rates and QRS durations within the range are considered as normal signals.
Is Lead 1 positive or negative?
By convention, lead I has the positive electrode on the left arm, and the negative electrode on the right arm, and therefore measures the potential difference between the two arms. In this and the other two limb leads, an electrode on the right leg serves as a reference electrode for recording purposes.
Which ECG lead is most important?
The most useful lead is V4R, which is obtained by placing the V4 electrode in the 5th right intercostal space in the mid-clavicular line.
What are the 3 types of ECG?
Types of ECG
a stress or exercise ECG – carried out while you’re using an exercise bike or treadmill. an ambulatory ECG (sometimes called a Holter monitor) – the electrodes are connected to a small portable machine worn at your waist so your heart can be monitored at home for 1 or more days.
Where do you put a V1?
Where does V1 need to be placed?
Placement of Lead V1
This is the 2nd intercostal space. Gently move your fingers over the 3rd rib to the 3rd intercostal space, and then over the 4th rib to the 4th intercostal space. The electrode is placed here (4th intercostal space right sternal border).
Is V1 lead negative?
With proper lead placement, the P wave is positive in V1-V2 (A). However, on moving the leads up to the 3rd intercostal space, the P wave in V1 is predominantly negative and in V2 has a negative component.
Can anxiety affect an EKG?
In patients without a known clinical history of anxiety or other mental health concerns, short-term nervousness can also disrupt ECG readings. In one case study from the Egyptian Journal of Critical Care Medicine, such apprehension led to reported quadrigeminy in all ECG leads.
