ECG Blog #118 (ECG Video-15) — QRST Changes (Applying a Systematic Approach)

-----------------------------------------

This is the 15th installment of my ECG Video Blog. This 65-minute video reviews QRST Changes (and Applying a Systematic Approach). There is a LOT of material in this video — so you may want to view it in more than a single session. Click on the link below for a detailed linked CONTENTS (so that you can easily navigate through the video).

-----------------------------------------

NOTE: There are advantages to using a video format format. These include:

• Ability to illustrate concepts not done full justice by the written word.
• Greater dispersion of my content through Google & YouTube. This material is free for anyone to use.

     This is the 15th installment of my ECG Video Blog (www.QRSTecg.com). This video is 65 minutes long — so you may want to view it in more than a single session. If you click on the description just below the Video on YouTube – you’ll see a detailed linked CONTENTS, so that you can easily navigate through the video. There are 3 main parts: i) Initial thoughts on the use of a Systematic Approach to ECG Interpretation; ii) Detailed discussion on how to assess for QRST Changes (assessing Q waves; R wave progression/Transition; ST-T wave changes); and iii) Practice Tracings that put concepts presented in the first 47 minutes of the video together. 

• NOTE: I aimed my content at an Intermediate level interpreter (with emphasis on BASIC concepts plus LOTS of PEARLS for more advanced interpreters along the way). 

Hope you enjoy this! I welcome your feedback! (Ken Grauer, MD – ekgpress@mac.com).

Figure-1: Schematic Figure from this video on QRST Changes (CLICK HERE to Fast Forward to 31:10 in the video where use of the PR & TP segment baselines is discussed). One could use either the PR or TP Baseline for assessing ST-T wave deviations. We often use a combination of both (depending on specifics for the tracing at hand). Below in the Figure we illustrate 1-2mm of ST depression (left) — and 2-3mm of ST elevation (right). NOTE — Enlarge by clicking on Figures — Right-Click to open in a separate window.
