Tachycardia Q&A

What is tachycardia?

Tachycardia is a type of arrhythmia defined by a fast heart rate that’s 100 beats per minute or higher. For comparison, a normal heart rate for adults is 60-100 beats per minute. Along with a rapid heart rate, you may also have an irregular heart rhythm.
You can develop several types of tachycardia, including:
  • Atrial fibrillation:
    Fast, irregular heartbeat originating in the heart’s upper chambers
  • Atrial flutter:
    Rapid heart rate of 250-350 beats per minute in the upper chambers
  • Paroxysmal atrial tachycardia:
    Fast, regular heart beat in the upper chambers
  • Paroxysmal supraventricular tachycardia:
    Fast, regular beat above the lower chambers
  • Ventricular tachycardia:
    Fast, regular beating in the lower heart chambers
  • Ventricular fibrillation:
    The lower chambers rapidly quiver
Ventricular fibrillation is the most dangerous type of tachycardia because it causes sudden cardiac arrest.

What causes tachycardia?

An electrolyte imbalance means you have high or low levels of potassium, sodium, magnesium, or calcium.
