Fragmented QRS complexes (fQRS) are defined by additional notches or slurs within the standard QRS waveform on a 12-lead electrocardiogram. These irregularities arise from heterogeneous ventricular ...
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 QRS complex consists of the Q wave, the R wave and the S wave. The QRS complex comes after the P wave when the SA nodal action potential travels through the AV node to the ventricles to cause ...
Narrow-complex tachyarrhythmias are rapid heart rhythms originating in the upper heart chambers, characterized by a QRS duration of less than 120 milliseconds on an EKG. These arrhythmias can be ...
A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...
