The risk is higher with a PVC burden greater than 20%. PVC burden often decreases spontaneously over time. [25] People who do not have heart disease (with ejection fractions greater than 40%) have the same long-term prognoses as the minority of people without PVCs on the 24 hours.
Ectopic beats are considered normal and are not indicative of cardiac pathology. Ectopic beats often remain undetected and occur as part of minor errors in the heart conduction system. They are rarely indicative of cardiac pathology, although may occur more frequently or be more noticeable in those with existing cardiac abnormalities.
The article has contained the following sentence for quite a long time: "Asymptomatic patients that do not have heart disease have long-term prognoses very similar to the general population, but asymptomatic patients that have ejection fractions greater than 40% have a 3.5% incidence of sustained ventricular tachycardia or cardiac arrest."
Heart disease and cardiovascular disease have almost the same meaning. However, heart disease specifically refers to conditions affecting the heart, while cardiovascular disease is a broader term ...
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...

The constant interval between the sinus beat and PVC suggests a reentrant etiology rather than spontaneous automaticity of the ventricle. [3] Premature atrial contractions by contrast do not have a compensatory pause, since they reset the sinus node, but atrial or supraventricular bigeminy can occur. If the PACs are very premature, the ...
