EKG Wave Components - PQRST. Before we get started, let’s briefly label the main components of an EKG waveform that will be discussed in this post. The P wave, QRS complex, and T wave are the parts of an EKG in which there are changes in voltage (waves). The region between 2 waves is called a segment.
Atrial and ventricular depolarization and repolarization are representedon the ECG as a series of waves: the P wavefollowed by the QRScomplex and the T wave. The first deflection is the P waveassociated with right and left atrial depolarization. The second waveis the QRScomplex. Why is it called the Pqrst wave?
P wave is due to atrial depolarisation. QRS is the ventricular depolarisation and T wave represents ventricular repolarisation. Atrial repolarisation is called Ta wave. The PQRST Heart Trace. An ECG will give a trace of a healthy heart that looks like the graph below. Each trace is a single heartbeat and therefore lasts about 0.8 seconds.

The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram. It is usually the central and most visually obvious part of the tracing; in other words, it's the main spike seen on an ECG line. It corresponds to the depolarization of the right and left ventricles of the human heart and contraction of the large ventricular muscles. In adults, the QRS complex …
Use the sequence 300-150-100-75-60-50-43-37. Count from the first QRS complex, the first thick line is 300 bpm, the next thick line 150 etc.
ECG interpretation always includes an assessment of the QT (QTc) duration. The QT duration represents the total time for de- and repolarization. It is measured from the beginning of the QRS-complex to the end of the T-wave.
Yes, this is a repeat, but it is an important repetition. The heart rate (bpm) can be determined from the ECG by measuring the time interval (s) between two successive beats (R-R interval), and dividing this into 60 s. Thus, if R-R interval = 0.6s heart rate = 60/0.6 = 100 bpm.
The P wave corresponds to the atrial depolalrization and the pumping of blood from the atrium to the ventricle.
