An electrocardiogram (ECG) records the electrical activity of the heart. It produces a trace of the heart working and the trace for an individual can be compared to that of a normal, healthy heart. A left atrial abnormality means that the ECG for the heart in question shows that there is something wrong with the electrical signal relating to the heart's left atrium.
The left atrium is one of four chambers in the heart. It receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve.
You need to get the doctor to explain the CAUSE of the anomalous electrical signal.
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
Check into left atrial enlargement. usually a sign of notched P waves
On an ECG the heart rate will match both ventricular rate and atrial rate if the heart is normal. If people have atrial fibrilation then the ventricular rate will be used on the ECG to work out the rate of the ventricular contraction and vice-versa with ventricular fibrilation. Usually both atrial and ventricular rates match so if the atria contracts at 70 BPM the ventricles will beat at 70 BPM. It is possible for the ECG machine to work out atrial or ventricular rate if needs be. Usually, however, if the ECG machine just displays heart rate then both ventricular and atrial rates match.
it depends in a structurally normal heart pvc's are not dangerous at all however if your heart structure has been altered by a heart attack or you were born with an abnormality there is a small risk of sudden death best to get it checked out on an ecg
the time between the two R waves in ECG
A large P wave on an ECG typically indicates an abnormality in the electrical activity of the atria of the heart. This could be due to conditions such as atrial enlargement, atrial fibrillation, or other atrial arrhythmias. Further evaluation by a healthcare provider may be needed to determine the underlying cause.
P wave corresponds to atrial depolarization in an ECG.

Right and left atrial depolarization produce a P wave on an electrocardiogram (ECG) waveform. This represents the depolarization of the atria as they contract to push blood into the ventricles.
The P wave on an ECG represents atrial contraction. It signifies the depolarization of the atria as they contract to push blood into the ventricles.
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
The P wave.
yes
i dont no
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
