An ECG reading typically consists of several waves and segments: - P Wave: Represents atrial depolarization. - QRS Complex: Indicates ventricular depolarization. - T Wave: Reflects ventricular repolarization. - PR Interval: Measures the time from the onset of atrial depolarization to the onset of ventricular depolarization. - ST Segment: Important in diagnosing myocardial ischemia or infarction.
