WebOct 12, 2024 · R and S waves. Assess the R wave progression across the chest leads (from small in V1 to large in V6). The transition from S > R wave to R > S wave should occur in V3 or V4. Poor progression (i.e. S > R through to leads V5 and V6) can be a sign of previous MI but can also occur in very large people due to poor lead position. WebIn electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°. This is reflected by a QRS complex positive in lead I and negative in leads aVF and II.. There are several potential causes of LAD. Some of the causes include normal variation, …

WebJul 14, 2009 · Around V3 or V4 the R waves become larger than the S waves and this is called the 'transitional zone'. If the transition occurs at or before V2, this is called counterclockwise rotation. If the transition occurs after V4, this is called clockwise rotation. Several studies have been done to understand the anatomical substrate for these rotations. WebR-wave amplitude in leads I, II and III should all be ≤ 20 mm.
