Understanding Arrhythmias and Heart Rhythm Disorders

Arrhythmias refer to abnormalities in the heart’s natural electrical system that cause the heart to beat too quickly, too slowly, or irregularly. Our cardiac electrophysiology team specializes in accurately diagnosing, treating, and managing all types of heart rhythm disorders.

Arrhythmias and Heart Rhythm Disorders

Arrhythmias occur when disruptions in the heart’s electrical signaling pathway cause abnormal impulse conduction. This results in irregular, fast, or slow heartbeats. While occasional skipped beats are common and usually harmless, some arrhythmias can indicate underlying disease or be life-threatening if left untreated.

Types of Arrhythmias and Heart Rhythm Disorders:

  • Atrial fibrillation (AF) is the most common arrhythmia. It occurs when the heart's upper chambers (atria) quiver instead of beating normally. AF can cause a fast, irregular heartbeat and can lead to blood clots, stroke, and heart failure.
  • Ventricular tachycardia (VT) is a type of arrhythmia that causes the heart's lower chambers (ventricles) to beat too fast. VT can be life-threatening if it is not treated.
  • Sinus bradycardia is a type of arrhythmia that causes the heart's rate to be too slow. Sinus bradycardia is usually not serious, but it can be a sign of a more serious underlying condition.
  • Supraventricular tachycardia (SVT) is a type of arrhythmia that causes the heart's upper chambers (atria) to beat too fast. SVT is usually not serious, but it can be uncomfortable.
  • Heart block is a type of arrhythmia that occurs when the electrical impulses that control the heart's rhythm are interrupted. Heart block can cause a slow heartbeat or a complete blockage of the electrical impulses.

The Rising Impact of Arrhythmias

Arrhythmias, or abnormal heart rhythms, are a growing public health concern. An estimated 2.7 million Americans are diagnosed with arrhythmias each year. As the population ages and more people survive cardiac events, the prevalence of arrhythmias is expected to keep rising. Understanding key data on arrhythmias can help raise awareness about this pressing issue. Some statistics that demonstrate the extent of arrhythmias include:

  • An estimated 6 million Americans have atrial fibrillation, the most common sustained arrhythmia. This number is projected to reach 12 million cases by 2030 as the population ages.
  • Ventricular arrhythmias cause over 300,000 deaths in the U.S. annually.
  • Atrial fibrillation is associated with a 3 to 5 times increased risk of stroke. It contributes to an estimated 15-20% of strokes.
  • Hospitalizations related to arrhythmias have increased by over 100% in recent decades as the population ages.
  • By 2060, it is projected that 9.4 million adults in the U.S. will have been diagnosed with atrial fibrillation.
  • Atrial fibrillation costs the U.S. approximately $6 billion in healthcare expenditures each year.

When To See a Cardiologist for Arrhythmias and Heart Rhythm Disorders

Arrhythmias can indicate underlying cardiovascular disease. Certain types like ventricular tachycardia can be life-threatening if left untreated. Even occasional skipped beats or fluttering may require monitoring. Don't delay if you notice possible arrhythmia symptoms. Early detection and treatment can greatly improve outcomes. Routine screening is also advised if you have risk factors like high blood pressure, heart disease, or sleep apnea. Ongoing evaluations are key for known arrhythmia patients to assess medications and treatments.

If you experience symptoms that may signal an arrhythmia, it is important to see a cardiologist promptly for evaluation and treatment. Some signs that warrant an urgent cardiac assessment include:

  • Feeling your heart race, flutter, or pound
  • Dizziness, lightheadedness, or fainting
  • Shortness of breath, fatigue, or chest pain
  • Confusion, impaired thinking, or memory issues
  • Anxiety or sense of impending doom
  • Frequent or sudden onset of arrhythmia symptoms
  • New exercise or stress intolerance
  • Lightheadedness causing falls or injury
  • Family history of arrhythmias or sudden cardiac death

Arrhythmias and Heart Rhythm Symptoms and Disorders We Treat

Arrhythmias and heart rhythm disorders can significantly impact a person's health and well-being. These conditions disrupt the heart's normal electrical signals, leading to irregular heartbeats, which can affect the heart's ability to pump blood effectively. As a result, vital organs may not receive sufficient oxygen and nutrients, leading to symptoms such as dizziness, fainting, shortness of breath, fatigue, and chest discomfort. In some cases, untreated arrhythmias can increase the risk of serious complications, including stroke, heart failure, and cardiac arrest. Here are some of the arrhythmias and heart rhythm symptoms and disorders we treat:

  • Dizziness & Fainting
    Arrhythmias can cause dizziness and fainting spells due to abnormal heart rhythms affecting blood flow to the brain. Our experts carefully evaluate and diagnose these symptoms to identify the underlying heart rhythm disorder and develop tailored treatment plans to manage and prevent future episodes.
  • Bradycardia
    Bradycardia is a condition characterized by an abnormally slow heart rate. Patients with bradycardia may experience fatigue, weakness, dizziness, or fainting. Our team conducts thorough assessments to determine the cause of bradycardia and recommends appropriate treatments, which may include lifestyle changes, medications, or pacemaker implantation.
  • Tachycardia
    Tachycardia refers to an excessively fast heart rate, which can lead to palpitations, shortness of breath, and chest discomfort. Our cardiologists employ state-of-the-art diagnostic tools to pinpoint the type and origin of tachycardia and then devise effective treatment strategies to restore a normal heart rhythm.
  • Atrial Fibrillation
    Atrial fibrillation is a common arrhythmia characterized by irregular and rapid heartbeats. This condition can increase the risk of stroke and heart-related complications. We offer various treatment options for atrial fibrillation, including medications, electrical cardioversion, ablation, and lifestyle modifications to manage symptoms and reduce risks.
  • Cardiac Arrest
    Cardiac arrest is a life-threatening emergency in which the heart suddenly stops beating. It requires immediate intervention to restart the heart's rhythm, typically through cardiopulmonary resuscitation (CPR) and the use of a defibrillator. Our team focuses on preventing cardiac arrest by identifying and managing underlying heart conditions.
  • Chronic Heart Failure
    Chronic heart failure is a condition in which the heart becomes weak and struggles to pump blood effectively. It can be associated with arrhythmias that worsen the condition. Our comprehensive approach to managing heart failure includes identifying and treating underlying arrhythmias to improve heart function and overall well-being.
  • Heart Block
    Heart block is a condition where the electrical signals that control the heart's rhythm are delayed or blocked. Depending on the severity, it may require pacemaker implantation to regulate the heart's electrical impulses and maintain a steady heartbeat.
