The heart’s rhythm is controlled by a natural electrical system. When this system malfunctions, it can lead to a heart that beats too fast, too slow, or irregularly. Cardiac rhythm management is a specialised field of cardiology that focuses on the diagnosis and treatment of these abnormal heart rhythms, also called arrhythmias. The goal is to restore and maintain a stable, healthy heart rhythm, allowing patients to live a full and active life.
Diagnosing rhythm disturbances
A cardiologist’s first step in managing a cardiac rhythm disturbance is to make an accurate diagnosis. The specialist will first discuss your symptoms, which might include palpitations, a racing heart, dizziness, or fainting.
The initial test is often a simple electrocardiogram (ECG), which records the heart’s electrical activity at rest. Since arrhythmias can be intermittent, a single ECG may not always capture the problem. In these cases, a doctor may recommend further investigations, such as:
- Ambulatory ECG monitoring: You wear a portable device to record your heart’s rhythm during your daily routine, which helps to capture infrequent episodes.
- Echocardiogram: An ultrasound of the heart that checks its structure and function, helping to identify any underlying causes for the arrhythmia.
These tests allow the specialist to pinpoint the exact nature of your heart rhythm disturbance. They can then develop a personalised treatment plan.
Treatment options
Once a cardiologist identifies the cause of an arrhythmia, they can recommend a variety of treatment options. The approach depends on the type and severity of the condition.
- Medication: A doctor may prescribe certain medicines to help control the heart rate and rhythm.
- Catheter ablation: A procedure in which a cardiologist uses a thin, flexible tube called a catheter to deliver heat or cold to a small area of heart tissue, correcting the electrical short circuit that is causing the arrhythmia.
- Cardiac device implantation: For a heart that beats too slowly, a doctor can implant a pacemaker to regulate the rhythm. In some cases, a doctor may use an implantable cardioverter-defibrillator (ICD) to treat dangerous fast rhythms.
