Explain the effect of ectopic atrium and ventricle.?
Answer:
Ectopy (in this context) refers to an electrical impulse coming from parts of the heart bar the SA (sinoatrial) or AV (atrioventricular) nodes. The SA node (in the R atrium) is our primary "pacemaker" ... it beats spontaneously at 60 - 100 (normally), conducting to the AV node (in the "centre" of the heart), later to the Bundle of His to the Purkinge fibres (which produce the ventricles to contract by squeezing from bottom to top).
"Ectopic beats" are seen on an electrocardiogram (ECG, aka EKG) as extra beat between regular beats. They go off because of "pacemaker cells" in other parts of the heart (usually within the atrium) sometimes beat faster than the SA node (if they pound more slowly, they don't cause ectopic beats).
Ectopic clusters contained by the ventricles cause ventricular ectopy contained by the same attitude but are much rarer.
Ablation of these cells (killing the clusters of cell that beat faster than the AV node) can be done by cooling (cryoablation) and heat by a microwave-tip catheter (thermoablation) -- both require a special catheter to be "snaked" through an artery then towards the element of the heart that's "acting up." Done in the cardiac catheterization (cath.) lab or electrophysiology (EP) lab at a hospital.
