In an electrocardiogram what is a U wave?
A U-wave is a wave which occurs after the T-wave. It can be made prominent by certain pathologies, particularly certain electrolyte imbalances, but research within the past decade or so has found that it is an essentially normal phenomenon which results from differences in the time it takes various types of cardiac cells to repolarize.
Which wave is the largest in the electrocardiogram?
The largest wave is the R
The QRS complex in an electrocardiogram results from?
An Electrocardiogram of a single heart beat shows three distinct waves. These are the P, QRS and T Waves. The QRS wave (normally the largest spike) in the electrocardiogram, is that of the ventricles depolarizing and contracting.
The p wave of a normal electrocardiogram indicates?
Atrial Depolarization.
On an electrocardiogram tracing atrial activity is represented by the?
p wave
What is required for the interpretation of the electrocardiogram?
Special training is required for interpretation of the electrocardiogram. To summarize in the simplest manner the features used in interpretations, the P wave of the electrocardiogram is associated with the contraction of the atria
What is the P wave of electrocardiogram closely followed by?
Contraction of both atria
Does the first heart sound occurs at the same time as the P wave of the electrocardiogram?
yes
What is the normal calibration for a EKG?
An abnormal ECG is when the electrocardiogram shows results outside the norm. These results are usually indicative of problems in the heart, such as enlargement, higher potassium or sodium levels, damage, and inflammation.
What are pea waves?
A "p" wave is a particular point on an electrocardiogram tracing. It represents the contraction of the right and left atria. The electrocardiogram tracing is a tool that the physician uses to evaluate the health of the heart.
What is the duration of a P wave?
The P wave refers to the electrocardiographic representation of electrical activation of the atrial myocardium. It can be measured using an electrocardiogram.
What would you see on the Electrocardiogram if the SA node did not fire?
An electrocardiogram would show reduced heart rate as other parts of the heart cause potentials at low rates. Also there would be no P wave.
