The QRS complex is positive in lead I and negative in lead II and also negative in lead aVF – indicating left axis deviation TIP When you see RBBB always look for 1 st degree heart block and/or left ...

In a “normal” electrocardiogram (ECG), the transition of the QRS axis in the precordial leads occurs between leads V 3 and V 4 (i.e., there is a dominant S in V 3 and a dominant R in V 4).

The ECG shows sinus tachycardia at about 115 beats per minute with a PR interval of about 0.15 sec (normal). The P waves show normal duration, but they are peaked in II, II and AVF and their amplitude ...

The ECG shows an irregularly irregular rapid ventricular rate, approximately 120 beats per minute, with no visible P waves. The frontal plane QRS axis is –30° and the R wave voltage in AVL is 15 mV.

Unfortunately I can't email it - it means that the heart is turned a little bit to the right - usually if slightly enlarged but it is not necessarily a sign of problems. Discover the Truth Step into a ...

Among the investigations currently used to classify hypertensive disorders of pregnancy (serum creatinine, fasting blood glucose, serum potassium and urinalysis), interpretation of the ECG is an ...
