1. Each small box equals 0.04 seconds. 2. Represents: atria to ventricular conduction time (through His bundle) It includes P wave and PR segment. Normal duration: 0.12-2.0 seconds (3-5 horizontal boxes). This is measured from the onset of the P wave to the onset of the QRS complex regardless if the initial wave is a Q or R wave. ST Segment and T wave In a sense, the term "ST segment" is a misnomer, because a discrete ST segment distinct from the T wave is usually absent.

The P wave represents the wave of depolarization that spreads from the SA node throughout the atria, and is usually 0.08 to 0.10 seconds (80-100 ms) in duration. The brief isoelectric (zero voltage) period after the P wave represents the time in which the impulse is traveling within the AV node (where the conduction velocity is greatly retarded) and the bundle of His.

The PR segment also serves as the baseline (reference line or isoelectric line) of the ECG curve. The amplitude of any deflection/wave is measured by using the PR segment as the baseline. PR segment: represents time from end of P wave to start of QRS complex. Cardiac event: impulse transmission through AV node, His bundle, bundle branches, & ventricular Purkinje system ± atrial repolarization; Considered baseline when evaluating for ST-segment elevation/depression; AV nodal conduction delay makes up most of PR segment PR segment elevation or depression in patients with myocardial infarction indicates concomitant atrial ischaemia or infarction.
