In cardiology, a normal Q wave is a small initial downward deflection following the P wave and preceding the R wave in a typical electrocardiogram (ECG). It represents the initial depolarization (contraction) of the ventricles as the electrical impulse from the atria passes through the ventricular septum. The presence of a normal Q wave is not uncommon and is considered a part of the normal variation in ECG readings. It is important to distinguish between a normal Q wave and an abnormal Q wave, which can be indicative of certain cardiac conditions such as a previous heart attack (myocardial infarction).
The Q wave is the first downward deflection after the P wave and the first element in the QRS complex. When the first deflection of the QRS complex is upright, then no Q wave is present. The normal individual will have a small Q wave in many, but not all, ECG leads.
