Arrhythmias are disorders of the heart’s rhythm that occur when the electrical impulses that control the heart’s beating are irregular. These disturbances can cause the heart to beat too fast (tachycardia), too slow (bradycardia), or irregularly, which can interfere with its ability to pump blood effectively. At Emerald Avenue Medical Clinic in Dubai Marina – JBR, we specialize in diagnosing and treating arrhythmias, providing comprehensive care to restore a normal rhythm and prevent complications.
Arrhythmias (Disturbances in Heart Rhythm) at Emerald Avenue Medical Clinic, Dubai
What is an Arrhythmia?
The heart has its own electrical system that regulates the heart rate and rhythm. An arrhythmia happens when something disrupts this system, causing the heart to beat in an abnormal pattern. Depending on the location and cause, arrhythmias can vary in severity and impact on heart health. They can occur in the upper chambers (atria) or the lower chambers (ventricles) of the heart.
Common types of arrhythmias include:
- Atrial Fibrillation (AFib): An irregular and often rapid heart rate that can increase the risk of stroke and heart failure.
- Ventricular Tachycardia (VT): A fast heart rate that originates in the ventricles and can be life-threatening.
- Bradycardia: An abnormally slow heart rate, often caused by a problem with the heart’s electrical system.
- Premature Ventricular Contractions (PVCs): Extra, abnormal heartbeats that disrupt the regular rhythm.
- Supraventricular Tachycardia (SVT): A rapid heart rate originating above the ventricles, often felt as palpitations.
- Conduction Disorders: Problems with the electrical signals traveling through the heart’s conduction system.
Symptoms of Arrhythmias
The symptoms of arrhythmias can vary greatly, depending on the type and severity. Some people may experience no symptoms at all, while others may have severe, life-threatening reactions. Common symptoms include:
- Palpitations: A sensation of rapid, fluttering, or irregular heartbeats.
- Dizziness or lightheadedness
- Shortness of breath
- Chest pain or discomfort
- Fatigue or feeling unusually tired
- Fainting (syncope) or near-fainting spells
- Sweating or cold sweats
- Confusion or difficulty concentrating
If you experience any of these symptoms, it’s important to consult with a cardiologist as arrhythmias can sometimes lead to more serious complications, such as stroke, heart failure, or sudden cardiac arrest.
Causes and Risk Factors of Arrhythmias
Several factors can contribute to the development of arrhythmias, including:
- Coronary artery disease or previous heart attack
- Heart failure
- Valvular heart disease
- Hypertension (high blood pressure)
- Electrolyte imbalances (e.g., low potassium or magnesium levels)
- Congenital heart defects
- Sleep apnea
- Excessive alcohol or caffeine consumption
- Certain medications that can interfere with the heart’s electrical system
- Thyroid disorders (hyperthyroidism or hypothyroidism)
- Stress or anxiety
- Family history of arrhythmias or sudden cardiac death
Diagnosis of Arrhythmias
To accurately diagnose arrhythmias and determine their cause, our cardiologists use several advanced diagnostic tools:
- Electrocardiogram (ECG): The most common test for detecting arrhythmias, an ECG records the electrical activity of the heart and helps identify abnormal rhythms.
- Holter Monitor: A portable ECG device worn for 24 to 48 hours to monitor heart activity throughout daily activities.
- Event Monitor: Similar to a Holter monitor, but used for longer periods to detect intermittent arrhythmias.
- Echocardiogram: A test that uses sound waves to create images of the heart, evaluating its structure and function.
- Stress Test: A test that evaluates how the heart responds to physical exertion, useful in identifying arrhythmias triggered by activity.
- Electrophysiological Study (EPS): A procedure where a catheter is inserted into the heart to map electrical activity and pinpoint the origin of the arrhythmia.
- Cardiac MRI or CT scan: These imaging tests help to evaluate the heart’s structure and blood flow.
Treatment Options for Arrhythmias
The treatment for arrhythmias depends on the type, cause, and severity of the condition. At Emerald Avenue Medical Clinic, we offer a wide range of treatment options to help restore normal heart rhythms and reduce the risk of complications.
Lifestyle Changes
- Stress management: Techniques like yoga, meditation, and deep breathing exercises can help reduce triggers like anxiety or stress.
- Avoidance of triggers: Limiting caffeine, alcohol, or certain medications that may exacerbate arrhythmias.
- Healthy diet: Consuming a heart-healthy diet that’s low in sodium and rich in fruits, vegetables, and whole grains.
- Regular physical activity: Tailored exercise plans to keep your heart healthy, but with caution depending on your specific arrhythmia.
Medications
- Antiarrhythmic drugs: To regulate and restore normal heart rhythm.
- Beta-blockers: To reduce the heart rate and prevent arrhythmias from occurring.
- Calcium channel blockers: To help regulate heart rhythm and lower blood pressure.
- Anticoagulants: To prevent blood clots, especially in conditions like atrial fibrillation.
Procedures and Surgical Interventions
- Cardioversion: A procedure to restore normal rhythm using electrical shocks, usually for arrhythmias like atrial fibrillation.
- Catheter Ablation: A minimally invasive procedure that targets the abnormal heart tissue causing arrhythmias, using radiofrequency energy to destroy it.
- Pacemaker: A small device implanted under the skin to regulate slow heart rhythms by sending electrical impulses to the heart.
- Implantable Cardioverter Defibrillator (ICD): A device implanted to monitor and correct life-threatening arrhythmias, such as ventricular tachycardia.
- Surgery: In some cases, surgical procedures may be required to treat underlying structural issues causing arrhythmias.
