Understanding Arrhythmia: Causes, Symptoms, and Treatment Options in Brampton, Mississauga, Caledon, and Milton

As a cardiologist serving patients in BramptonMississaugaCaledon, and Milton, Ontario, I often encounter individuals experiencing arrhythmia, a condition that affects the heart’s rhythm. Arrhythmia refers to irregularities in the heart’s electrical system, causing abnormal heartbeats. These abnormal rhythms can be too fast, too slow, or erratic, leading to a variety of symptoms, including palpitationsshortness of breathchest pain, and dizziness. While some arrhythmias are harmless, others can be life-threatening and require immediate medical attention.

In this article, I will discuss the causes, symptoms, diagnosis, and treatment options for arrhythmia, and explain how seeking care from a heart doctor or cardiologist near me can improve your heart health and well-being.

What is Arrhythmia?

An arrhythmia occurs when the electrical signals that regulate the heart’s rhythm malfunction, causing the heart to beat in an irregular pattern. The heart’s electrical system controls the heart’s rate, rhythm, and coordination of its contractions. When these signals become disrupted, the heart may beat too fast (tachycardia), too slow (bradycardia), or irregularly. This can impair the heart’s ability to pump blood efficiently and lead to symptoms such as dizzinesspalpitationsshortness of breath, and chest pain.

There are several types of arrhythmias, including:

  • Atrial Fibrillation (AFib): The most common type of arrhythmia, atrial fibrillation causes the atria (upper chambers of the heart) to beat rapidly and erratically. This irregular rhythm increases the risk of stroke and can lead to symptoms like palpitationsshortness of breath, and fatigue.
  • Atrial Flutter: Similar to atrial fibrillationatrial flutter causes the atria to beat quickly, but in a more organized pattern. Although it can cause similar symptoms to AFib, atrial flutter may be easier to treat in some cases.
  • Ventricular Tachycardia (VT): A fast, abnormal rhythm originating in the ventricles (the heart’s lower chambers), ventricular tachycardia can be life-threatening if not treated promptly. It can lead to dizzinesschest pain, and even sudden cardiac arrest.
  • Ventricular Fibrillation (VFib): A very serious arrhythmia, ventricular fibrillation occurs when the ventricles quiver instead of contracting properly, causing a complete lack of blood flow to the body. Immediate medical intervention, such as defibrillation, is required to prevent death.
  • Bradycardia: This condition occurs when the heart rate is too slow, typically under 60 beats per minute. It may cause dizzinessfatigue, and fainting, and can be dangerous if left untreated.
  • Postural Orthostatic Tachycardia Syndrome (POTS): POTS is a condition that causes an abnormal increase in heart rate when transitioning from lying down to standing. This can cause symptoms like dizzinesspalpitations, and shortness of breath.

What Causes Arrhythmias?

Arrhythmias can result from various factors, including:

  1. Heart Disease: Conditions like coronary artery diseaseheart failure, and heart valve problems can increase the risk of arrhythmias. These conditions can disrupt the heart’s electrical pathways, leading to irregular heartbeats.
  2. High Blood PressureHypertension can damage the heart and blood vessels over time, increasing the likelihood of arrhythmias.
  3. Electrolyte Imbalances: Low levels of electrolytes like potassium, magnesium, and calcium can interfere with the electrical signals in the heart, leading to arrhythmias.
  4. Medications: Some medications used to treat heart conditions, high blood pressure, or other health issues can trigger arrhythmias as a side effect.
  5. Alcohol and Stimulants: Excessive alcohol consumption, caffeine, nicotine, and recreational drugs can disrupt the heart’s rhythm and contribute to arrhythmias.
  6. Thyroid Problems: An overactive or underactive thyroid can affect the heart’s electrical system and cause irregular heartbeats.
  7. Genetic Factors: Some arrhythmias are inherited and can affect the electrical pathways in the heart from birth.
  8. Sleep Apnea: Untreated sleep apnea can lead to low oxygen levels, which can trigger arrhythmias, especially during sleep.

Symptoms of Arrhythmia

The symptoms of arrhythmia can vary depending on the type and severity of the irregularity. Common symptoms include:

  • Palpitations: A sensation of a fast, pounding, or irregular heartbeat.
  • Shortness of Breath: Difficulty breathing, especially during physical activity or even at rest.
  • Chest Pain: A feeling of tightness, discomfort, or pain in the chest, often associated with an arrhythmia.
  • Dizziness or Lightheadedness: A sensation of faintness or feeling off-balance, which can occur if the heart is not pumping blood effectively.
  • Fatigue: A feeling of tiredness or weakness that does not improve with rest.
  • Fainting or Near-Fainting: In severe cases, arrhythmias can cause a drop in blood pressure, leading to a loss of consciousness.

If you experience any of these symptoms, it’s important to seek medical attention. A cardiologist or heart doctor near me can help determine the cause of your symptoms and recommend the appropriate treatment.

Diagnosing Arrhythmia

To diagnose arrhythmia, a cardiologist will perform a thorough evaluation, including:

  1. Medical History: Your heart doctor will ask about your symptoms, lifestyle, and family medical history to identify potential risk factors for arrhythmias.
  2. Physical Examination: A physical exam helps the cardiologist assess signs of arrhythmia, such as abnormal heart sounds or signs of heart failure.
  3. Electrocardiogram (ECG or EKG): This test records the electrical activity of the heart and is essential for diagnosing arrhythmias.
  4. Holter Monitor: A portable ECG device worn over 24 to 48 hours to monitor heart rhythms during daily activities.
  5. Echocardiogram: This ultrasound of the heart can help assess the heart’s structure and function, identifying any underlying conditions that may contribute to arrhythmias.
  6. Stress Test: A stress test may be used to monitor the heart’s rhythm during physical exertion.
  7. Electrophysiology Study (EPS): In some cases, an invasive test may be performed to map the heart’s electrical system and pinpoint the source of the arrhythmia.

Treatment Options for Arrhythmia

The treatment for arrhythmia depends on its type, severity, and underlying cause. Common treatment options include:

  1. Medications: Anti-arrhythmic drugs, such as beta-blockers, calcium channel blockers, and anticoagulants, can help control heart rate, rhythm, and prevent blood clots.
  2. Cardioversion: A procedure in which electrical shocks are delivered to the heart to restore a normal rhythm, often used for atrial fibrillation or atrial flutter.
  3. Catheter Ablation: A procedure in which a catheter is used to destroy the abnormal electrical pathways causing the arrhythmia. This is commonly used for atrial fibrillationatrial flutter, and ventricular tachycardia.
  4. Pacemaker: A small device implanted under the skin to regulate the heart’s rhythm, often used for bradycardia or other slow heart rhythms.
  5. Implantable Cardioverter-Defibrillator (ICD): A device that monitors the heart’s rhythm and delivers shocks if it detects life-threatening arrhythmias, such as ventricular tachycardia or ventricular fibrillation.
  6. Lifestyle Changes: Reducing alcohol intake, quitting smoking, managing high blood pressure, and maintaining a healthy weight can help reduce the risk of arrhythmias.
  7. Surgery: In rare cases, surgery may be required to repair heart valves or treat other underlying conditions contributing to arrhythmias.

When to See a Cardiologist
