The P wave is the first wave in an ECG complex, and it results from the atria depolarizing. It may not be present in arrhythmias where the atria do not necessarily depolarize, such as junctional or ventricular escape rhythms, and at times when the atria are depolarizing abnormally this will be reflected in the P wave's replacement by abnormal waves, such as the low-amplitude "squiggle" seen in atrial fibrillation, or the "sawtooth" pattern seen in atrial flutter.

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.
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
On an electrocardiogram tracing atrial activity is represented by the?
p wave
The p wave of a normal electrocardiogram indicates?
Atrial Depolarization.
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 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 generates the p wave of an electrocardiogram?
A P wave denotes atrial depolarization or when your atriacontracts. It is generated by the Sinoatrial (SA) node which is the primary pacemaker and signifies a Sinus Rhythm.
What waves are found on an electrocardiogram?
There are no waves in an electrocardiogram. An electrocardiogram (ECG) is performed by putting electrodes on the body and measuring heart activity directly.
The p wave of the electrocardiogram is a signal from?
The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.
How is sodium chloride used during a electrocardiogram?
Sodium chloride is not used during electrocardiogram.
