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 would be a patients ecg show with Hypocalcemia?

The ECG of a patient with hypocalcemia will show q number of different distinct patterns. The ECG will show a T wave that is inverted and flattened, a prolongation of the QT interval, a narrowing of the QRS complex, a prolonged ST and ST depression, a reduction in the PR interval, and a prominent U wave.

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.


What does a inverted QRS wave indicate?

In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.


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 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

How does hyponatremia effect your ecg?

Some electrocardiographic (ECG) findings associated with hypokalemia include flattened or inverted T waves, a U wave, ST depression and a wide PR interval. Due to prolonged repolarization of ventricular Purkinje fibers, a prominent U wave occurs, that is frequently superimposed upon the T wave and therefore produces the appearance of a prolonged QT interval


When was QRS Records created?
