As a medical professional with expertise in cardiology, I can provide you with information regarding Q waves on an ECG.
In a normal ECG, the presence of a Q wave is not unusual. When the first deflection of the QRS complex is upright, then no Q wave is present. However, a normal individual will typically have a small Q wave in many, but not all, ECG leads. It's important to note that the size and duration of the Q wave can vary depending on the lead being observed.
Abnormalities of the Q waves are often indicative of more serious conditions, such as myocardial infarction (heart attack), and are discussed in more detail within the relevant sections of ECG literature.
