Types of Arrhythmias

Depending on in which there are disturbances of the heart, all divided by the sinus arrhythmia, atrial and ventricular.

Another feature of the arrhythmia is heart rate.

  • If the heart rate is above 80 beats per minute and talk about tachycardia. Heart rate can be increased by physical or emotional stress (this is a normal reaction of a healthy heart.) Increased body temperature also causes tachycardia. It is believed that the increase in body temperature of 1 degree leads to an increase in heart rate of 10 beats. Tachycardia may be a sign of many diseases, but it can be a normal variant.
  • A condition in which frequency heart rate less than 60 beats per minute is called bradycardia. Bradycardia can also be a completely healthy people. It is generally observed in athletes. Moderate bradycardia creates favorable conditions for the blood supply to the heart muscle, as the blood it can come only when it is in a state of relaxation (ie, between beats). Should be distinguished from bradisfigmiyu bradycardia — slow heart rate at a normal heart rate. Bradisfigmiya observed when contractions of the heart does not generate perceptible pulse waves.

Funds are also the so-called paroxysmal arrhythmias (Paroxysm — attack suddenly arisen state). It apparently healthy person suddenly appears extremely frequent palpitations — rhythmic or irregular, the attempt to count the pulse is simply not possible for an inexperienced person, it exceeds the rate of 150-200 beats per minute. The human condition in this case, depending on the type of paroxysm can range from weakness and general malaise to rapid loss of consciousness. Most heart attack ends as abruptly as it had begun, some paroxysms require immediate medical attention. If we assume arrhythmia signal danger, paroxysmal disorders are the most serious of them.

In the case where arrhythmia there a long time, talking about the constant abuse of rhythm. Of these criteria is sufficient to describe the arrhythmia in which the reduction Serce occur at regular intervals, such as paroxysmal atrial tachycardia. However, there are many arrhythmias in which the heart beats irregularly.

Here are the most common ones.

1) If the correct heart rhythm woven premature reduction, talk about arrythmia. The most common reasons are its vegetative-vascular dystonia, myocardial myocarditis, gallbladder disease, smoking or stress. Arrhythmias often arise bezvidimoy reasons. Normally, a healthy person per day can occur up to 1,500 premature beats that do not require treatment and do not affect health.

2) When one of the most common arrhythmias — atrial fibrillation — Lost one of the phases of the cardiac cycle — namely, the atria. Their muscle fibers lose their ability to work in sync. As a result, the atria only randomly twitch — shimmer. From this and the ventricles begin to contract spasmodically. Arrhythmias in snoring and obstructive sleep apnea syndrome are very specific. At the time of respiratory failure develops bradycardia (slow heart rate), and the ventilation phase after apnea is marked tachycardia (accelerated heart rate). Sometimes, the fluctuation range of 30-40 beats per minute, and these jumps can be repeated every minute, and even more often. Under the arrhythmias, which are characterized by rapid change of frequency and regularity of the heart rate to slow or sudden, the work of the heart is disturbed significantly — so much so that reduces the volume of blood ejected into the aorta. In such cases, the person in need of medical care, as they can be life-threatening.
