A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. This term can be confusing, as not all ECG leads contain all three of these waves; yet ...

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.

Paired, identical-looking QRS complexes can be a consequence of many factors, such as every other beat being atrial, a junctional premature beat (atrial or junctional bigeminy), or 3:2 AV ...

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 ...

Did you know that certain medications can cause symptom of 'Electrocardiogram QRS complex'. Find these drugs listed on the page and be warned of similar symptoms as possible side-effects.

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...

Answer The ECG is abnormal and he should be referred to Cardiology Explanation The PR interval is very short indicating a bypass of the AV node via an accessory pathway. The QRS complexes also look ...

From this spot, Don's ECG recordings were dramatically improved and never inconclusive. The amplitude of the QRS complexes increased from 2 to 16 mm!

Did you know that certain medications can cause symptom of 'Electrocardiogram QRS complex prolonged'. Find these drugs listed on the page and be warned of similar symptoms as possible side-effects.
