WebPathological Q-waves are ≥0,03 s and/or amplitude ≥25% of R-wave amplitude in same lead, in at least 2 anatomically contiguous leads. Is the R-wave progression in the chest leads (V1–V6) normal? Is the electrical axis normal? Electrical axis is assessed in limb leads and should be between –30° to 90°. Common findings

WebThe output of an ECG recorder is a graph (or sometimes several graphs, representing each of the leads) with time represented on the x-axis and voltage represented on the y-axis. A dedicated ECG machine would usually print onto graph paper which has a background pattern of 1mm squares (often in red or green), with bold divisions every 5 mm in ...
