I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order.
P Wave, Q-R-S Waves and the T Wave
The P Wave on and ECG shows depolarization of the Atria, and the characteristics should be smooth, round, no more than 2.5 mm in height, no more than .11 seconds in duration, and positive in leads I,II, aVF, and V2 through V6.
The P wave on an electrocardiogram (ECG) represents atrial depolarization, which is the electrical activity that triggers the contraction of the atria. It occurs when the sinoatrial (SA) node generates an electrical impulse that spreads through the atria, causing them to contract and push blood into the ventricles. The P wave is typically the first deflection seen on the ECG, preceding the QRS complex.
the ventricular depolarization, which masks the atrial repolarization wave on the electrocardiogram. This is because the QRS complex is much larger than the atrial repolarization wave and overlaps with it, making it difficult to distinguish on the ECG.
The P wave corresponds to atrial depolarization, specifically the spread of electrical impulses through the atria causing them to contract and pump blood into the ventricles. This is the first wave in an electrocardiogram (ECG) and represents the beginning of the cardiac cycle.
An absence of P wave in an ECG may indicate atrial fibrillation, a condition where the atria of the heart quiver instead of contracting effectively. This can lead to irregular and fast heart rhythms. Further evaluation by a healthcare provider is necessary to determine the underlying cause and appropriate management.
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
the P wave
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
No, the T wave is not higher than the QRS complex in this ECG reading.
The T wave is positive in an ECG due to the direction and charge. This positive deflection occurs after each QRS complex.
The T wave in an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.
The T wave on an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.
The T wave in an ECG represents the repolarization of the ventricles in the heart, indicating the recovery phase before the next heartbeat.
The P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing in an ECG.
