Heart Rhythm Disorders

When Your Heart's Electrical System Needs Attention

Your heart’s electrical system coordinates each heartbeat with precise timing. Arrhythmias occur when this system malfunctions, causing your heart to beat too fast, too slow, or irregularly. These conditions range from harmless to life-threatening, making expert evaluation essential.

Types of Rhythm Disorders we Treat

Atrial Fibrillation (AF) The most common arrhythmia, where the heart’s upper chambers quiver instead of beating effectively. Dr. Naidoo has particular expertise in AF management.

Bradycardia Slow heart rate (below 60 beats per minute) that may cause fatigue, dizziness, or fainting.

Tachycardia Rapid heart rate (over 100 beats per minute at rest) including:

  • Supraventricular tachycardia (SVT)
  • Ventricular tachycardia
  • Atrial flutter

Ectopic Beats Extra or skipped beats often felt as palpitations or fluttering.

Recognising Arrhythmia Symptoms

Symptoms vary by type but may include:

  • Palpitations or racing heart
  • Fluttering in the chest
  • Dizziness or lightheadedness
  • Fainting or near-fainting
  • Shortness of breath
  • Chest discomfort
  • Fatigue or weakness
  • Anxiety about heart sensations

Some arrhythmias cause no symptoms but still require treatment to prevent complications.

Comprehensive Diagnostic Approach

Pinpointing Your Rhythm Problem

Accurate diagnosis guides effective treatment:

Diagnostic Tools:

 

  • 12-lead ECG for immediate rhythm assessment
  • Holter monitoring (24-48 hour recording)
  • Event recorders for intermittent symptoms
  • Exercise stress testing
  • Echocardiography to assess heart structure
  • Referral for Electrophysiology studies when needed


Dr. Naidoo’s advanced ECG interpretation skills ensure accurate diagnosis of complex arrhythmias.

FAQs

Quick Answers to Common Questions

Most palpitations are harmless, caused by stress, caffeine, or ectopic beats. However, persistent palpitations, those associated with dizziness, chest pain, or fainting, need evaluation. Dr. Naidoo can differentiate benign from concerning rhythms through proper assessment.

While AF often requires ongoing management, some patients achieve long-term rhythm control through medication, cardioversion, or ablation procedures. Even when cure isn't possible, excellent symptom control and stroke prevention allow normal, active lives. Treatment success depends on AF type, duration, and underlying causes.

Modern pacemakers typically last 8-15 years, depending on settings and usage. Battery life is monitored at regular check-ups, allowing planned replacement before depletion. The procedure for battery replacement is simpler than initial implantation, usually requiring just the generator change.

Most patients don't feel their pacemaker functioning. Initially, you may be aware of the device under your skin, but this sensation diminishes. Occasionally, patients feel a flutter when the pacemaker performs automatic checks. Dr. Naidoo ensures optimal programming for comfort and effectiveness.

Many patients with well-controlled arrhythmias exercise normally. Dr. Naidoo provides specific exercise guidelines based on your condition, treatment, and fitness level. Some arrhythmias improve with regular exercise, while others require activity modification. Proper management allows most patients to remain active.
