Tachycardia is a rapid heart rate of more than 100 beats per minute. Sinus tachycardia, from the heart's sinus node, is a normal response to exercise, illness, or stress.
There are several types of abnormal tachycardias or Arrhythmias. These can come from two places:
- Atria (the two smaller chambers on the top of the heart)-called supraventricular tachycardias
- Ventricles (the lower chambers of the heart)-called ventricular tachycardia
This condition can be life-threatening. But, it can be treated. If you think you or someone you know has this condition, get emergency help.
