There are several types of tachycardia. This condition is defined as an increase in heart rate, that is, the number of heart beats per unit of time. According to the US National Library of Medicine, this pathology falls within arrhythmias, including brachycardia (decreased heart rate) and irregular pulse.
Clinical studies estimate that the incidence of sudden cardiac death in the general population is 1 in 1000 people per year in Western Europe. Despite the low percentage of the population affected, it is essential to know the types of cardiac alterations to be prepared. On this occasion, we address in detail the forms of tachycardia.
About tachycardias and their distribution
Before immersing ourselves fully in these arrhythmic processes, we are interested in shedding some data collected by epidemiological studies that put into perspective the importance of tachycardias at a global level. We show you some representative figures:
Supraventricular tachycardias, which we will describe in later sections, affect 0.4 to 1% of the population, especially the elderly.
Syndrome Wolff-Parkinson-White (WPW) , heart pathology involved tachycardias, has an estimated incidence of 0, 04 people per 1000 individuals. Of course, its sudden death rate can reach 4%.
Focal atrial tachycardia affects 0.34% of the young population, although these are asymptomatic.
As we can see, eventual tachycardias are episodes that anyone can experience, but that these are translated into pathologies is more complex. Their incidence is very low, but even so, understanding them is essential to rule out a serious clinical picture.
