The normal duration (interval) of the QRS complex is between 0.08 and 0.10 seconds — that is, 80 and 100 milliseconds. When the duration is between 0.10 and 0.12 seconds, it is intermediate or ...

Because the normal ventricular conduction system (His-Purkinje) is used, the QRS complex is frequently narrow. A junctional rhythm is normally slow — less than 60 beats per minute.

In addition to 'Electrocardiogram QRS complex', there may be other similar symptoms or signs that better match your side effect. These have also been listed below for your convenience.

What is the mechanism for the progressive widening of QRS complexes and for the normal narrow QRS complexes observed in the ECG of a 52-yo male with recurrent syncope?

There are clearly extra QRS complexes that are of different morphology compared to the QRS complexes with preceding p waves, ie, the sinus beats. The extra QRS complexes are broader and bigger ...
