Cardiac Arrythmia

Arrhythmia is an irregular heartbeat. It can be too fast, too slow, or just irregular. It occurs due to improper working of electrical impulses that coordinate heartbeats. Arrhythmias are of different types:

  • Bradycardia: Slow heart rhythm where the heart beats less than 60 times per minute.
  • Supraventricular arrhythmias: Arrhythmias that begin in the upper chambers of the heart are called “Atria”
  • Ventricular arrhythmias: Arrhythmias that begin in the lower chambers of the heart called “Ventricles”.

Frequently Asked Questions

Can arrhythmia be cured?

Medications are used to control abnormal heart rhythms; ablation procedures can cure some types of arrhythmia completely. Once treated, whether, through ablation or ongoing medications, most patients with a heart rhythm issue can return to their normal activity levels. 

Is arrhythmia a serious problem?

Most people have experienced arrhythmia or irregular heartbeats. Although usually harmless, sometimes an arrhythmia increases your risk of a more serious heart condition.

What is the difference between heart palpitations and arrhythmia?

A heart that beats irregularly, too fast, or too slow is experiencing an arrhythmia. Palpitation is a short-lived feeling like a feeling of a heart-racing or of a short-lived arrhythmia. Palpitations may be caused by emotional stress, physical activity, or consuming caffeine or nicotine.
