Dysritmie II: Classificatie van Tachyritmieën

Tachyarrhythmia is a type of dysrhythmia where the heart rate exceeds 100 beats per minute.

Here are some common types of tachyarrhythmias:

First, sinus tachycardia originates from increased impulses from the sinus node, often triggered by stress, leading to an elevated heart rate.

Next, premature atrial contractions are early heartbeats initiated by an ectopic focus within the atria, resulting in skipped beats or palpitations.

Atrial flutter, due to a conduction defect in the atrium, results in a rapid, regular atrial impulse that exceeds the AV node's conduction capacity.

In contrast, atrial fibrillation is marked by chaotic atrial signals that produce irregular and often fast heartbeats, significantly increasing the risk of stroke.

Furthermore, paroxysmal supraventricular tachycardia is characterized by sudden episodes of rapid heartbeats due to abnormal electrical pathways above the ventricles.

Similarly, ventricular tachycardia is when the ventricles beat uncontrollably fast, usually due to past heart damage.

Lastly, ventricular fibrillation involves disorganized electrical activity in the ventricles, severely disrupting blood circulation.
