Arrhythmias classification


The human heart usually beats 60 to 100 times a minute. The heart beats less than 60 times a minute, that's how one speaks of a Bradycardia. This can be for example Competitive athletes, where it has no disease value, or at Heart disease occur. If there is an acceleration of the heartbeat, so that the heart more than 100 times beats in the minute, this is known as Tachycardia. Tachycardia can under pressure or even after Enjoyment of caffeine occur.

One is always desirable regular heartbeat. If this is available, it is called this Sinus rhythm. If the heart gets out of rhythm, there is a cardiac arrhythmia. Depending on whether the heart too fast, too slow or irregular beats, one differentiates tachycardia (Heart beats more than 100 times per minute), bradycardia (Heart beats less than 100 times per minute) and arrhythmic Cardiac arrhythmias.

examples for tachycardiac arrhythmias:

  • Atrial flutter
  • Atrial fibrillation
  • Ventricular tachycardia (ventricular tachycardia)
  • Ventricular flutter
  • Ventricular fibrillation
  • AV nodal reentry tachycardia
  • Atrioventricular reentry tachycardia
  • Focal atrial tachycardia
  • Atrial reentry tachycardia

examples for bradycardiac arrhythmias:

  • Sinus bradycardia
  • Sinoatrial block (SA block)
  • Atrioventricular block (AV block)
  • Bundle branch block.

In addition, cardiac arrhythmias can still occur after Place of their creation organize. So there is supraventricular Arrhythmias that originated above the AV node or in the AV node (AV node = atrioventricular node or "atrial ventricular node", it belongs to the cardiac conduction system), so take primarily in the atria. There is also a corresponding ventricular Arrhythmias that are below the AV node, especially in the Chambers of the heart, develop. Arrhythmias come through Abnormalities in electrical excitation or the electrical excitation line conditions. According to this, there is another way of classifying cardiac arrhythmias. So you can also between Arousal disorders and Conduction disorders distinguish.

examples for Arousal disordersthat arise in the sinus node:

  • Sinus tachycardia
  • Sinus bradycardia
  • Sinus arrhythmia

examples for Conduction disorders:

  • Sinoatrial block (SA block)
  • atrioventricular block (AV block)
  • Bundle branch block
