THE electrocardiographic picture of prolonged QRS-complex duration with short PR interval was the subject of isolated reports 1,2 until Wolff, Parkinson and White 3 described the clinical syndrome of ...
The rhythm is irregular, but the long intervals are the same (↔) and the short intervals (┌┐) are the same. One premature QRS complex (↑) is observed. Therefore, the rhythm is regularly irregular. The ...
The mechanism of the benefits achieved with the therapy has been attributed to resynchronization of the dyssynchronous segments resulting from bundle branch block, especially left bundle branch block ...
Cardiac dyssynchrony is the proposed mechanism for pacemaker-induced cardiomyopathy, which can be prevented by biventricular pacing. Left bundle branch pacing and His bundle pacing are novel ...
Pace mapping and visual comparison of the local pacing response with the intrinsic QRS morphology form the mainstay of His bundle pacing (HBP). We evaluated the performance of a surface lead ...
This is the last in a three-part series on using an electrocardiogram to assess the heart’s electrical activity. In this article, the focus is on cardiac rhythm and conduction abnormalities of the ...
Patients who are acutely ill, or at risk of becoming so, are not always nursed in critical care. Developing skills in basic observation and electrocardiogram monitoring enables nurses to care for ...
This wide QRS complex tachycardia has a typical left bundle branch block pattern, but two things give the clue that this is ventricular tachycardia. There is a fusion beat (second from left) present ...
