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).

After 100 years, the 12-lead electrocardiogram (ECG) remains the most accessible and inexpensive noninvasive diagnostic and prognostic tool in cardiology. Almost every hospitalized patient will ...

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.

Background Interpretation of the athlete’s ECG is based on differentiation between benign ECG changes and potentially pathological abnormalities. The aim of the study was to compare the 2010 European ...

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 ...
