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.
The largest wave is the R
Atrial Depolarization.
p wave
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
Contraction of both atria
Repolarization of ventricular muscle fibers.
yes
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.
The P wave refers to the electrocardiographic representation of electrical activation of the atrial myocardium. It can be measured using an electrocardiogram.
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.
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.
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.
