About Heart Rhythm
Heart rhythm is the rate and pattern at which your heart beats. Whenever the impulse that signals your heart to beat is interrupted or distorted, your heart rhythm will be irregular, and your heart may not pump blood effectively.
While experiencing an irregular heartbeat, also called arrhythmia, you may feel:
You can experience irregular heartbeats in your chest, throat or neck. You may feel pounding, racing or your heart skipping. Your heart will beat at a different rate:
- Normal: A normal heart beats 60-100 times per minute.
- Ventricular tachycarida: If your heart is beating more than 100 times per minute, you may be experiencing ventricular tachycardia.
- Bradycardia: If your heart is beating less than 55 times per minute, you may have bradycardia.
Atrial fibrilation, or Afib, is the most common type of irregular heartbeat. If you have atrial fibrillation, you experience a rapid heartbeat when certain parts of your heart contract quickly in an irregular pattern.
If your health care provider believes you have Afib, you will be tested with coronary angiography, echocardiogram, electrophysiologic study, exercise treadmill test, or a nuclear imaging test.
Atrial Fibrillation Causes:
Ventricular tachycardia is a rapid heartbeat that begins in the ventricles. A person experiencing ventricular tachycardia may feel chest pain, light-headed, dizzy, or short of breath. They may even faint or lose consciousness
Ventricular tachycardia can be diagnosed by an electrocardiogram (EKG) or by an electrophysiology study.
Ventricular Tachycardia Causes:
- Heart failure
- Valvular heart disease
- As a result of a heart attack or heart surgery
