this occurs with a premature beat known as a PAC (premature atrial contraction) A t wave is ventricular repolarization (the ventricle getting ready to beat again. A premature atrial contraction may happen at this time but you can discern the actual p wave as it is hidden in the t wave. Pac's are normal, most people have them occasionally. They can increase with stress, caffeine, smoking. The other cause would be in an irregularly fast arrhythmia in with the heart is beating so fast that the p wave is coming very close to the t wave and hard to discern it

What wave comes after the t wave of an ECG?
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
What does a inverted QRS wave indicate?
In QRS wave, P wave shows atrial contraction or depolarisation whereas, T wave shows ventricular repolarisation.
How does the P wave the qrs complex and t wave relate to the electrical and mechanical evemts of the cardiac cycle?
its related to the dialysis
What has the author T P Cotter written?
T. P. Cotter has written: 'Collision kinetics in a shock wave' 'Potentialities and problems of nuclear rocket propulsion'
What is the first wave of an ECG?
The first wave of an ECG is the P wave, which represents atrial depolarization as the electrical impulse spreads through the atria. It is the initial wave seen in a normal heart rhythm.
How do you calculate the period of a wave from its frequency?
T=Period F=frequency T=1/F Period=1/F
What do the letters PQRST represent?
P, Q, R, S and T each represent a wave of the electrocardiogram (ECG). The waves, and the ECG in general, confer a graphic representation of the hearth's electric activity. The ECG of a healthy person usually contains three waves, called the P wave, the QRS complex and the T wave. The P wave corresponds to the electric depolarization of the auricles, the QRS complex corresponds to the electric depolarization of the ventricles and the repolarization of the auricles, and the T wave corresponds to the electric repolarization of the ventricles. A complete period of an ECG (that is, the P, QRS, and T waves) represents the electrical activity of the heart for one pulse.
What does a segment of an ECG tracing indicate?
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
What is the ECG of a normal human?
A normal ECG of a human will show a P wave, QRS complex, and T wave. The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization. These waves correspond to the electrical activity of the heart during each phase of the cardiac cycle.
Which is faster an s-wave or a p-wave?
P-Wave
Is surface wave faster then a p wave?
no a p wave is faster than s wave
Immediately before the P wave?
The P wave represents atrial depolarization in an ECG, so it occurs just before the P wave on the ECG tracing. It signifies the activation of the atria as they prepare to contract and pump blood into the ventricles.
