Heart Rhythm Disorders

What are heart rhythm disorders?

Heart rhythm disorders, also known as arrhythmias, occur when the electrical signals that control the heartbeat become irregular, too fast or too slow.

Some common heart rhythm disorders include:

  • Atrial fibrillation (AF)

  • Supraventricular tachycardia (SVT)

  • Bradycardia (slow heart rhythm)

  • Premature atrial or ventricular beats

Some rhythm disturbances are brief and benign, while others require ongoing management and monitoring. Experiences can vary widely — from minimal symptoms to palpitations, fatigue or reduced exercise tolerance.

Why it matters?

Heart rhythm disorders can affect how efficiently the heart pumps blood around the body as well as influence how confidently and comfortably someone is able to move and exercise.

Depending on the type and severity, arrhythmias may:

  • Increase the risk of stroke or heart failure

  • Reduce exercise tolerance and daily function

  • Cause symptoms such as palpitations, dizziness, breathlessness or fatigue

  • Impact confidence with movement and physical activity

Our support and exercise approach

Exercise Physiology support focuses on helping people remain active, confident and safe while living with a heart rhythm condition.

This includes:

  • Individually prescribed exercise that respects rhythm history, symptoms and medical advice

  • Guidance around safe exercise intensity, pacing and recovery

  • Gradual progression of aerobic and resistance exercise to support cardiovascular fitness and functional capacity

  • Education to build confidence with movement and recognise exercise-related symptoms

  • Ongoing review and adaptation as symptoms, confidence or medical guidance change

  • A collaborative approach with your healthcare team to ensure exercise and lifestyle strategies align with your broader care plan.
