Left Ventricular Hypertrophy. A number of different criteria and scoring systems exist for the determination of LVH on the ECG. A commonly used one is the Estes (or more correctly the Romhilt-Estes) system. It has reasonable specificity (85-95%), but sensitivity is low. Estes Scoring System for Left Ventricular Hypertrophy 3. This is scored o 6 ...

Leads III and AVF are also used with this criteria. Left Atrial Abnormality (LAA) is also known as LAE and LAH (left atrial enlargement and left atrial hypertrophy). Another name for this abnormality is P mitrale. Here, the P-waves in Leads II, I, or L are prolonged to 120 msec or 0.12 sec or three small boxes. ...
Right Atrial Enlargement (RAE) ECG Review- Criteria and Examples …
Left atrial enlargement. Left atrial enlargement is typically characterized by an increase in the terminal portion of the P wave. Best seen in lead II, this terminal deflection is often demonstrated as a distinct second peak within the P wave (arrow below). In some leads, this second peak gives the P …
