Comprehensive tutorial on ECG interpretation, covering normal waves, durations, intervals, rhythm and abnormal findings. From basic to advanced ECG reading. Includes a complete e-book, video lectures, clinical management, guidelines and much more.

Figure 3. The electrical activity on an ECG (EKG). The areas represented on the ECG are summarized below: V1, V2 = RV; V3, V4 = septum; V5, V6 = L side of the heart; Lead I = L side of the heart; Lead II = inferior territory; Lead III = inferior territory; aVF = inferior territory (remember ‘F’ for ‘feet’) aVL = L side of the heart; aVR ...

A normal ECG is illustrated above. Note that the heart is beating in a regular sinus rhythm between 60 - 100 beats per minute (specifically 82 bpm). All the important intervals on this recording are within normal ranges. 1. P wave: upright in leads I, aVF and V3 - V6; normal duration of less than or equal to 0.11 seconds

Learn about the T-wave, physiology, normal appearance and abnormal T-waves (inverted / negative, flat, large or hyperacute), with emphasis on ECG features and clinical implications.

Feb 28, 2011 · A simple, step-by-step guide to reading an ECG (also known as ECG interpretation), with included ECG examples and ECG quiz questions.

Right ventricular hypertrophy causes large R-waves in V1–V3 and smaller R-waves in V4–V6. Pre-excitation, bundle branch block and chronic obstructive pulmonary disease (COPD) may also affect R-wave progression.

Oct 8, 2024 · Wellens syndrome is a pattern of inverted or biphasic T waves in V2-3 (in patients presenting with/following ischaemic sounding chest pain) that is highly specific for critical stenosis of the left anterior descending artery. There are two patterns of …

Jan 9, 2025 · What are V1, V2, V3, V4, V5, V6 in ECG? The V1 to V6 leads in an electrocardiogram (ECG) are chest leads that provide a specific view of the heart's electrical activity from different angles on the chest. Here's a breakdown of their specific placements: Fourth intercostal space, right sternal border. Fourth intercostal space, left sternal border.

Jan 14, 2021 · 1. On a right-sided ECG, V1 and V2 remain on the same place. V3 to V6 are placed on the same place but mirrored on the chest. So V4 is in the middle of the right clavicle. The ECG should be marked as a Right-sided ECG. V4R (V4 but right sided) is a sensitive lead for diagnosing right ventricular infarctions. 2.

Mar 5, 2011 · An overview of ECG interpretation, including the different components of a 12-lead ECG, cardiac axis and lots more.
