What are normal ECG parameters?

Normal ECG values for waves and intervals are as follows: RR interval: 0.6-1.2 seconds. P wave: 80 milliseconds. PR interval: 120-200 milliseconds.

What are the waveforms in a normal ECG?

Normal EKG tracings consist of waveform components that indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U.

What are the components of the ECG waveform?

There are three main components to an ECG: the P wave, which represents the depolarization of the atria; the QRS complex, which represents the depolarization of the ventricles; and the T wave, which represents the repolarization of the ventricles.

How is ECG interpreted?

When interpreting the heart rhythm, you should look for P waves, which is a sign of atrial excitation. When every P wave is followed by a QRS complex, the ECG shows sinus rhythm. If the P waves are irregular, sinus arrhythmia is likely present.

What do each of the waves on an ECG mean?

Q wave is first deflection downwards R wave is the next deflection upwards if it passes the isoelectric line and change to positive S wave is the next deflection downwards T wave indicate repolarization of the ventricles. QT interval determines repolarization and depolarization of the ventricles

What are the different types of ECG waves?

The up and down lines that you see on an electrocardiogram defines different types of waves, segments and intervals. There are different types of waves observed on ECG which denote depolarization and re-polarization of muscles of ventricle and atrium. They are P wave, R wave, S wave and T wave.

What does an EKG wave mean?

An electrocardiogram (ECG) wave, sometimes called an elektrokardiogramm (EKG) wave, is a diagnostic tool used by clinicians to analyze the electrical activity of the heart in order to determine heart health. The heart contracts to propel blood through the body and contraction is achieved through a series…

What is normal ECG Wave?

Normal ECG wave: A normal ECG makes a specific pattern of three recognizable waves in a cardiac cycle. These wave are- P wave, QRS wave and T-wave, P-R interval, S-T segment. P-wave: It is a small upward wave that appears first.
