During sinus rhythm, the 12-lead electrocardiogram showed a complete left bundle branch block with a prolonged PR interval. During tachycardia, the QRS morphology was identical; however, no P waves were visible (Figure 1). The cycle length during tachycardia varied between 440 and 490 ms.Teis...

How to measure the QT interval--what is normal? The QT interval extends from the beginning of the QRS complex to the end of the T wave. Since the report of Jervell and Lange-Nielsen in 1957, it has been difficult to determine whether to measure a QT or a QU interval. U waves are ...
There is a P wave, the PR interval, and the QT interval which contains the QRS complex, the ST segment, and the T wave. There are a lot of variables to take into consideration when reading an ECG like current medications and medical history. Knowing this will help determine if the ...
Since it induces conduction block in the AV node, adenosine has diagnostic utility in patients with narrow QRS complex tachycardia. Similarly, adenosine could be of the most value in hemodynamically stable wide QRS tachycardia (WQRST) with 1:1 VA conduction when there is difficulty in ...
Measurement of the QT interval is also difficult in the setting of a wide QRS complex related to either ventricular conduction defects or a paced QRS complex. This is primarily because of the lack of a standard method to measure the QT interval in this setting; data on the best way to mak...
