EKG BASICS
This is what an EKG Measures
What is the electrical activity of the heart?
This is a normal heart rhythm
What is normal sinus rhythm?
This interval measures from the start of P to the start of the QRS.
What is the PR interval?
This limb lead is placed on the right arm
What is RA?
This is the first thing you should check if the EKG tracing looks irregular
What is checking for loose electrodes?
This is the normal resting heart rate range for adults.
What is 60-100 beats per minute?
This rhythm is over 100 BPM
What is tachycardia?
This interval represents ventricular depolarization and repolarization
What is the QT interval?
This lead is placed on the left leg
What is LL?
This position is used for most EKG recordings
What is supine position?
This wave represents atrial depolarization
What is the P wave?
This rhythm is under 60 BPM
What is bradycardia?
This wave represents ventricular repolarization
What is the T wave?
This chest lead is placed at the 4th intercostal space, right side
What is V1?
This type of interference is caused by muscle movement or shivering
What is a somatic artifact?
This part represents ventricular depolarization
What is the QRS complex?
This rhythm has no organized electrical activity
What is ventricular fibrillation?
A prolonged PR interval may indicate this condition
What is a heart block?
This chest lead is placed at the 5th intercostal space, midclavicular line
What is V4?
This pattern appears as a flat line and may indicate a serious condition or lead issue
What is asystole?
This segment represents early ventricular repolarization
What is the ST segment?
This rhythm shows chaotic atrial activity with no clear P waves
What is atrial fibrillation?
A small square on EKG paper represents this amount of time
What is 0.04 seconds?
This lead is placed at the 4th intercostal space, left side of the sternum
What is V2?
This important step must be completed before starting the EKG to ensure correct results
What is verifying a patient's identity?
