A normal ECG consists of three characteristic waves: the P wave, representing atrial depolarization; the QRS complex, representing ventricular depolarization; and the T wave, representing ventricular repolarization. These waves reflect the electrical activity of the heart during a cardiac cycle.
The three types of deflection waves seen in a typical ECG are the P wave (atrial depolarization), the QRS complex (ventricular depolarization), and the T wave (ventricular repolarization). They represent the different electrical activities of the heart during each phase of the cardiac cycle.
When the ECG is running at normal speed, the paper is moving at 25 mm/sec.
PQRST represents the five key components of a normal cardiac cycle on an ECG trace: P wave (atrial depolarization), QRS complex (ventricular depolarization), T wave (ventricular repolarization), and sometimes the U wave (late ventricular repolarization). Analyzing these waves helps to identify abnormalities in the heart's electrical activity.

The deflection waves in an ECG tracing include the P wave (atrial depolarization), QRS complex (ventricular depolarization), and T wave (ventricular repolarization). Each of these waves represents different electrical activity of the heart during a cardiac cycle.
Two T waves on an ECG indicate that the heart's electrical activity is normal and functioning properly.
In an ECG reading for atrial fibrillation (AFib), there will be irregular and rapid electrical signals in the atria, leading to a chaotic heart rhythm. This is shown as erratic waves on the ECG tracing. In a normal ECG reading, the heart's electrical signals follow a regular pattern, resulting in a steady and organized heart rhythm with distinct waves on the ECG tracing.
The key differences between an ECG reading of atrial fibrillation and a normal ECG are irregular heart rhythm and absence of distinct P waves in atrial fibrillation. These differences can be identified by observing the irregularity in the R-R intervals and the presence of fibrillatory waves instead of P waves. Interpreting these differences can help diagnose atrial fibrillation and guide appropriate treatment.
In an ECG showing atrial fibrillation (AFib), the rhythm appears irregular with no distinct P waves, and the QRS complexes may be normal. In contrast, a normal ECG rhythm shows regular intervals between heartbeats, clear P waves before each QRS complex, and consistent QRS complexes.

T waves on an ECG represent the repolarization of the ventricles of the heart, indicating the relaxation phase of the heart's electrical activity.
T waves in an electrocardiogram (ECG) represent the repolarization of the ventricles in the heart, indicating the recovery phase after contraction.
The three types of deflection waves seen in a typical ECG are the P wave (atrial depolarization), the QRS complex (ventricular depolarization), and the T wave (ventricular repolarization). They represent the different electrical activities of the heart during each phase of the cardiac cycle.

An ECG provides information about the wearer of the ECG's heartrate and rhythm of the heart. It provides information about wether it is normal or abnormal.
