which is wide-complexed since it does not use the normal ventricular conduction system. There is a compensatory pause after the PAC. The extra atrial action potential causes the SA node to become ...

Ectopic, originating outside of the SA node, and thus the QRS morphology would be different from the normal morphology when the action potential travels through the normal conduction system.

In the search for alternative pacing strategies, conduction system pacing—stimulation of the heart's natural electrical conduction pathways—has gained increasing attention. His bundle pacing ...

The ESC Clinical Consensus Statement offers updated guidance to healthcare professionals on selecting patients for conduction system pacing.  Patient perspective has been incorporated to ensure a ...

Cardiovascular disease (CVD) is the leading cause of death and disease burden worldwide. Macrophages are important components ...
