How do you calculate the PR interval?
RR interval 795 QRS interval 140 What is PR interval??
What happens during the S-T interval?
The S-T interval represents the initial slow phase of ventricular repolarization. It is the time between completion of the QRS complex and beginning of the T-wave

What is an s-p interval?
The s-p interval is a measure of time that reflects the duration between the onset of ventricular depolarization (measured by the ventricular conduction time, QRS complex) and the onset of ventricular repolarization (measured by the T wave). It is used in electrocardiography to help assess the electrical activity of the heart.
What is an electrocardiogram's QRS pattern?
QRS-- A pattern seen in an electrocardiogram that indicates the pulses in a heart beat and their duration. Variations from a normal QRS pattern indicate heart disease.
What is R-R interval?
The R-R interval is a medical term used to describe the peak of one QRS to another. This is used to asses the ventricular rate.
Why do some fire companies have Quick Response Service QRS instead of an ambulance?
The Volunteer Fire Company I work at has A Quick Response Service or (QRS). The QRS Vehicle is a 1999 Chevrolet suburban 2500 4x4. We use our QRS o respond to medical calls in our area? I am wonder why some Fire companies like mine use Quick Response units? what is the difference between a QRS unit and an Ambulance. Our QRS doesn't carries people but it carries equipment and backboards. Why are QRS used instead of an ambulance. Thanks. :)
How do you measure the duration of a QRS complex?
The start of the QT interval is the first deviation from the isoelectric line following the p wave and the end is the last time the waveform crosses the isoelectric line before the T-wave begins. The waveform may well corss the isolelectric line several times before the end of the QRS interval. Normal measurement is less than or equal to .12 In simple terms, it is the start and end of the "spiky" high-frequency part of the waveform.
What does a QRS duration reading of 144 mean?
A QRS duration reading of 144 milliseconds indicates a prolonged ventricular conduction time. Normally, the QRS duration should be between 70 to 100 milliseconds; a reading of 144 ms suggests that there may be a delay in the electrical conduction through the ventricles, which can be due to various conditions, such as a bundle branch block or other forms of intraventricular conduction delay. This finding may require further evaluation by a healthcare professional to determine the underlying cause and appropriate management.
How is PR interval measured in electrocardiography?
PR (Pulse Rate) intervals are measured by using the gap between the beginning of the P wave (the excitation of the atria) and the beginning of the QRS , a typical deflection seen on an ECG (Electrocardiogram).
What is an s p interval?
An S-P interval is the time interval between the end of the QRS complex on an electrocardiogram (ECG) and the beginning of the T wave. It represents the time taken for the electrical impulse to travel from the ventricles through the AV node to the atria, allowing for ventricular filling before the next heartbeat. Changes in the S-P interval can indicate cardiac conduction abnormalities.
What is a normal QRS Duration in EKG?
0.04 - 0.12 sec (one small box - 3 small boxes)
