Tachycardia is the point when your heart beats more than 100 per minute. It is fairly common, especially after exercising, drinking caffeine, or experiencing strong emotions.
If a person has not engaged in such activities before the increased heart rate, it may be caused by an underlying issue. Examples are an abnormal heart rhythm that may develop into further complications and health problems if left untreated.
However, for some types of tachycardia, treatment is not needed.
Types and Causes
These are some types of tachycardia and their corresponding causes:
- Sinus Tachycardia. It is the most common type that many people experience. This type is caused by emotions, anxiety, exercise, fever, or caffeine beverages. Still, tachycardia treatment is recommended. In a few cases, heart rate increases due to anemia, hyperthyroidism, heart complications, and severe bleeding.
- Supraventricular Tachycardia (SVT). In this type, the upper part of the heart is affected, called the atria. When the atria receive short electric signals, the heart beats faster than normal. Most of the time, it is not dangerous. The serious matter is it still can be associated with heart problems. SVT is most likely to happen those who are anxious, exhausted, heavy caffeine and alcohol drinkers, or smokers.
- Ventricular Tachycardia. The lower part of the heart, called the ventricles, is affected in this type of tachycardia. It is caused by abnormal electric signals and results in a fast heart rate. Underlying causes include lack of oxygen in heart tissue, cardiomyopathy, medications, illicit drugs, and sarcoidosis. For this type, tachycardia treatment from doctors is needed.
Our heart pumps blood through the entire body, but once it beats abnormally, other organs will be affected, resulting in the following:
