Standard ADC components seldom provide enough flexibility to meet the conflicting needs of today’s medical designs. By Ian ...

There are two different rates that can be determined on an ECG. The atrial rate is indicated by the frequency of the P waves. The ventricular rate is indicated by the frequency of the QRS complexes.

A junctional rhythm occurs when the electrical activation of the heart originates near or within the atrioventricular node, rather than from the sinoatrial node. Because the normal ventricular ...

At a glance, the tracing appears to show sinus rhythm with first-degree AV block and junctional bigeminy. However, careful observation of the V1 lead shows regularly occurring P waves (↓ in Figure 2) ...

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 ...

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 ...
