Tachycardia

By: Ashtyn Bray

Tachycardia

A heart rate of more than 100 beats per minute

How It Happens

The rapid heartbeat does not allow enough time for the heart to fill before it contracts so blood does not get pumped throughout the body

Causes

  • Lack of oxygen to areas of the heart due to lack of coronary artery blood flow
  • Cardiomyopathy in which the structure of the heart becomes distorted
  • Medications

Symptoms

  • Dizziness
  • Lightheadedness
  • Unconsciousness
