Stepwise interpretation of ECG
ID 279 – RVH

ID 279 – This 57 year old woman who had rheumatic fever at age 17 has been suffering from severe dyspnea and fatigue during the past year

ID 279 – Normal sinus rhythm, 80/min
Yes: The P waves originate from the sinus node– The rhythm is regular , the rate is 80/min.– Each P is followed by a QRS - The PR interval is normal – NORMAL SINUS RHYTHM, 80/min

ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement
There are signs of left atrial enlargement

Let’s now look at the QRS complexes: There is Right axis deviation
ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation

Let’s now look at the QRS complexes: There is Right axis deviation
ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation

The QRS duration is normal : There is no right bundle branch block, left bundle branch block or non-specific block
ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation

There is right ventricular hypertrophy
ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation Right ventricular hypertrophy
![Page 9: stepwise interpretation of ECG ID279 RVH](https://reader035.fdocuments.us/reader035/viewer/2022062319/556481dcd8b42a361d8b4b5d/html5/thumbnails/9.jpg)
There are no QRS signs of myocardial infarction
ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation Right ventricular hypertrophy

There is ST depression in II, III, aVF and the right chest leads (V1-V3) may be due to RVH –There are negative T waves in V4-V6. Diffuse T changes are not uncommon in patients who are in heart failure. They may be due to ischemia
ID 279 – Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation Right ventricular hypertrophy

There is ST depression in II, III, aVF and the right chest leads (V1-V3) may be due to RVH –There are negative T waves in V4-V6. Diffuse T changes are not uncommon in patients who are in heart failure. They may be due to ischemia
ID 279 – Final diagnosis: Normal sinus rhythm, 80/min – Left atrial enlargement – Right axis deviation Right ventricular hypertrophy with ST-T abnormalities
