What is the flat line on an ecg called?
isoelectric lines!
Why use P Q R S T on the ECG?
Willem Einthoven invented the ECG in 1903. The letters P Q R S T were assigned to the points on the ECG because it was thought that there may be more points in either direction to be found. The letters remained in use out of common practice even after it was determined there were no further points to be labelled.
What confounding variables can interfere with an ECG?
jewlrey, medications, movement, lead placement, metal buttons,
What is atrial repolarization indicated by?
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
What is a line that is not a line but is almost a line?
A line of best-fit.
What is the flat line on an ecg called?
isoelectric lines!
What components of the ECG are normally measured along the isoelectric line?
st segments
What is polarization in the electrocardiogram?
Polarization in an electrocardiogram (ECG) refers to the resting state of the heart's electrical activity, when no electrical impulses are being generated. This is represented by the flat line (isoelectric line) between heartbeats on the ECG tracing.
What is any deviation either up or down from zero to the isoelectric line when taking an EKG?
What is any deviation either up or down from zero to the isoelectric line when taking
Why does hypocalcemia prolong the QT interval If calcium influx is compromised by hypocalcemia how is the isoelectric plateau phase maintained much less prolonged as manifested by the ECG?
more potassium
What is point between qrs and st segment on ekg called?
what does isoelectric line represent
What does it mean if there is no heart beat and a straight line on an ECG?
then there dead
Which line in the ECG should you read?
The main line to read on an ECG is the "QRS complex," which represents the ventricular depolarization. This is the most informative part in determining heart rate, rhythm, and conduction abnormalities.
What is the flat horizontal line that separates the various waves of the ECG cycle?
its a flat horizontal line separator....
Which speces is not isoelectric to Mg2?
Oxygen
What is a flat line on the ECG tracing of one of the leads is typically caused by?
A loose or disconnected wire.
What does a straight line on an ECG represent?
A flat section of line indicates no muscular activity in the heart at that particular instant; a constantly flat line indicates heart failure.
