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
