Atrial flutter: description
Atrial flutter is a rhythm disorder that originates from the right atrium of the heart. In atrial flutter, the electrical signal of the sinus node "comes off the path" and forms so-called circular excitations in the right atrium. This stimulates the atria up to 300 times per minute. The electrical signals are also forwarded to the heart chambers. However, in the cardiac conduction system there is protection (a so-called block through the AV node) from too rapid excitations. Only every second, third or fourth signal is actually passed on to the muscle cells of the chambers. The heart beats then up to 150 times per minute.
Sometimes this blockage of electrical excitations stops. Then so many excitations are transmitted to the ventricles that they beat at a rate of up to 300 per minute. Those affected quickly become unconscious.5 Facts about the pacemakerIf you want to do sports with a pacemaker? Does the device sit right in the heart? And how big is it?

Atrial flutter: symptoms
Since the heart beats very fast in atrial flutter (more than 150 times per minute), those affected almost always feel an unpleasant heart rate and heart palpitations. You feel tired, breathless and dizzy. Many feel a pressure on the chest. The arrhythmia usually starts suddenly. The pulse is fast and regular.
