WebThese T waves are suggestive of a severe stenosis of the proximal left anterior descending coronary artery and, left untreated, can progress to a large anterior ST elevation infarction. Weba downward propagating wave. Klemp and Lilly (197 5) extended this reflected wave theory to a multilayer atmosphere. Their model suggests that downslope windstorms occur when the atmosphere is tuned so that partial reflections at each interface produce an optimal superposition of upward and downward propagating waves. Durran (1986) introduced a WebThe T-wave amplitude is highest in V2–V3. The amplitude diminishes with increasing age. As noted above, the transition from the ST segment to the T-wave should be smooth. The T-wave is normally slightly asymmetric since its downslope (second half) is steeper than its upslope (first half). hydro-consult engineering limited
