Arrhythmia - Irregular Heartbeat

Arrhythmia occurs when your heart beats too fast (tachycardia), too slow (bradycardia), or irregularly. Thus, causing the heart to beat improperly, which leads to ineffective blood pumping.  

Sometimes it may be normal for a person to have a slow or fast heart rate. However, some heart arrhythmias may cause bothersome and even life-threatening problems.  

Types of Heart arrhythmias are grouped by the speed of the heart rate:


a fast heart (resting heart rate is greater than 100 beats a minute)

  • Atrial fibrillation (A-fib)
  • Atrial flutter
  • Supraventricular tachycardia
  • Ventricular fibrillation
  • Ventricular tachycardia 


a slow heartbeat (resting heart rate is less than 60 beats a minute)

  • Sick sinus syndrome
  • Conduction block 

Arrhythmia may not cause any signs or symptoms but may be detected through a health screening .

Signs and symptoms of arrhythmias:

What causes arrhythmia?


How is arrhythmia being diagnosed?

  • Physical exam and questions about your medical history and symptoms
  • Some tests may be required to confirm the irregular heartbeat and conditions that can cause arrhythmias (heart or thyroid disease)

Tests to diagnose heart arrhythmias may include:

Electrocardiogram (ECG)

measures the timing and duration of each electrical phase in the heartbeat

Holter monitor*

portable ECG device which can be worn for a day or more to record your heart’s rhythm as you go about your routine

*A Holter monitor test may be done if a traditional electrocardiogram (ECG or EKG) doesn’t provide enough details about the heart’s condition. If the irregular heartbeats are infrequent, a longer-term monitor called an event recorder may be needed.
