Parts of the ECG explained P waves. P waves represent atrial depolarisation. In healthy individuals, there should be a P wave preceding each QRS complex. PR interval. The PR interval begins at the start of the P wave and ends at the beginning of the Q wave. It represents the time taken for electrical activity to move between the atria and the ventricles. QRS complex

The T-wave. Assessment of the T-wave represents a difficult but fundamental part of ECG interpretation. The normal T-wave in adults is positive in most precordial and limb leads. The T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age. As noted above, the transition from the ST segment to the T-wave should be smooth.

P Wave. In a normal ECG, there's three distinct waves. Together these waves represent one heartbeat. Looked at separately, the waves …

EKG Application. As the ventricles repolarize, there is another change in voltage across the cell membrane as the cells become more negative again. This will result in another wave on EKG, known as the T wave. The T wave represents ventricular repolarization and …
Electrocardiogram Waves - My EKG

Waves are the different upward or downward deflections represented on the EKG tracing. They are the product of the action potentials created during the cardiac stimulation, and repeated from one heart beat to another, barring alterations.
ECG Waveforms | ECG Techniques and Recognition
https://iheartecg.wordpress.com/2013/02/26/ecg-waveforms/
The heart’s electrical activity is represented on the monitor or ECG tracing by three basic waveforms: the P wave, the QRS complex, and the T wave. A U wave is sometimes present. Between the waveforms are the following segments and intervals: the PR interval, the PR segment, the ST segment, and the QT interval.

The three waves of the QRS complex represent ventricular depolarization. For the inexperienced, one of the most confusing aspects of ECG reading is the labeling of these waves. The rule is: if the wave immediately after the P wave is an upward deflection, it is an R wave; if it is a downward deflection, it is a Q wave:

P-wave: The first little “hump” or “bump” you see is known as the P-wave. Remember from the electrical conduction lecture, that the SA node is responsible for this. Study tip: The P-wave represents ATRIAL DEPOLARIZATION (depolarization is a big, fancy word for CONTRACTION). QRS Complex: The next area you see is a big spike. This spike is called the QRS complex.

Each ECG cycles consists of 5 waves: P, Q, R, S, T corresponding to different phases of the heart activities. The P wave represents the normal atrium (upper heart chambers) depolarization; the QRS complex (one single heart beat) corresponds to the depolarization of the right and left ventricles (lower heart chambers); the T wave represents the re-polarization (or recovery) of the …

A normal heart rhythm contains a P wave, a QRS, and a T wave.³ Knowing the normal amplitude, deflection, and duration of each component is essential to accurate rhythm and EKG/ECG interpretation. Amplitude: This measures the voltage of the beat and is determined by how high the wave reaches, as measured by each square vertically on the chart. 10 mm = 1 mv. …
