Tachycardia is the irregular or accelerated heart rhythm of the heart, it is usually when the heartbeat exceeds 100 beats per minute, and can reach up to 400. It is considered a quite dangerous problem since, at this rate, the heart it does not have the ability to pump oxygen-rich blood throughout the body.

This anomaly can occur both in the upper chambers of the heart in which case it would be called atrial tachycardia, while those that occur in the lower chambers of the heart are called ventricular tachycardia.

There is a wide variety of abnormal tachycardias, which are classified depending on the origin and the cause that produces the excessively accelerated heartbeat. The most common variants of tachycardia are the following:

  • atrial fibrillation This is the name given to the accelerated heart rate that occurs due to the chaotic and irregular electrical impulses that occur in the upper chambers of the heart.
  • Atrial flutter, in this case the atria of the heart beat rapidly, but at a regular rate. This accelerated rate generates faint contractions of the atria.
  • Supraventricular tachycardia. This has its origin in an area above the ventricles. It occurs because of abnormalities in the circuitry of the heart that are usually present at birth and start a cycle of overlapping signals.

If the heart beats too fast, it most likely stops pumping blood efficiently to the rest of the body. This can be a problem since it does not allow oxygen to reach the organs and tissues, and in addition to this it can cause the following signs and symptoms that are related to tachycardia: First, difficulty breathing, it may be accompanied by lightheadedness, a racing pulse, a racing, bothersome, or abnormal heartbeat, or a “jumping” feeling in the chest, just to mention a few of the more common ones.

Regarding its prevention, this always depends on what is the reason that generates it, for that reason, in the case of tachycardias, it is to know exactly if the origin is internal or it occurs due to the effect of external factors that have been able to alter the normal state of the patient.
