____ induce vagal stimulation of the cardiac conduction system, specifically the SA and AV nodes.
____ is the most common dysrhythmia seen in clinical practice
____ is a synchronized countershock that may be performed in emergencies for unstable ventricular or supra ventricular tachydysrhytmias or electively for stable tachydysrhythmias that are resistant to medical therapies.
____ is an invasive procedure that may be used to destroy an irritable focus causing a supra ventricular or ventricular tachydysrythmia.
Radiofrequency catheter ablation
____ are also call remature ventricular contractions, result from increased irritability of ventricular cells and are seen as early ventricular complexes followed by a pause.
Premature ventricular complexes
____ is an asynchronous countershock, depolarizes a critical mass of myocardium simultaneously to stop the re-entry circuit, allowing the sinus node to regain control of the heart.
____ is a general term for the inability of the heart to work effectively as a pump.
