What Is Arrhythmia?

Arrhythmia refers to an abnormal heart rhythm and is generally classified as either a rapid heartbeat (tachycardia) or a slow heartbeat (bradycardia). The diagnostic approach and treatment strategy vary depending on the specific type of arrhythmia.

Types of Arrhythmia

Tachycardia (fast heart rate)

  • Atrial fibrillation
  • Paroxysmal supraventricular tachycardia (PSVT)
  • Ventricular tachycardia

Bradycardia (slow heart rate)

  • Sick sinus syndrome
  • Atrioventricular (AV) block

Other types

  • Heart failure with dyssynchrony
  • Vasovagal syncope
  • Ventricular premature complexes

Symptoms of Arrhythmia

Common symptoms of arrhythmia include:

  • Palpitations
  • Chest discomfort
  • Dizziness
  • Fatigue
  • General weakness
  • Syncope (fainting)

What Causes Arrhythmia?

  • Coronary artery disease
  • Heart failure
  • Cardiomyopathy
  • Valvular heart disease
  • Genetic disorders

Risk Factors of Arrhythmia

  • Advanced age
  • Hypertension
  • Diabetes mellitus
  • Obesity
  • Sleep disorders (e.g., sleep apnea)
  • Smoking
  • Excessive alcohol use

Prevention of Arrhythmia

  • Manage underlying health conditions
  • Control high blood pressure, diabetes, and high cholesterol
  • Seek timely treatment for heart disease, including coronary artery disease and heart failure
  • Limit alcohol and reduce caffeine intake
  • Engage in regular physical activity
  • Quit smoking
