Arrhythmias are disorders of the heart’s rhythm, causing the heart to beat too fast, too slow, or irregularly. Patients may notice palpitations, fluttering, skipped beats, or chest discomfort.
At Heart & Vascular Specialists DFW, we specialize in evaluating arrhythmias and palpitations to identify underlying causes, prevent complications, and develop personalized treatment plans.
Atrial fibrillation (AFib) – irregular, rapid heart rhythm that increases stroke risk
Premature atrial or ventricular contractions (PACs/PVCs) – extra beats felt as palpitations
Tachycardia – abnormally fast heart rate
Bradycardia – abnormally slow heart rate
Other rhythm-related symptoms – palpitations, skipped beats, or fluttering sensations
Patients with arrhythmias may experience:
Rapid, slow, or irregular heartbeat
Fluttering or “skipped” beats
Dizziness or lightheadedness
Shortness of breath
Chest discomfort or pressure
Fatigue or reduced exercise tolerance
Prompt evaluation is important to prevent complications such as stroke, heart failure, or syncope.
Our cardiologists use advanced testing to detect and monitor arrhythmias, including:
Electrocardiogram (EKG/ECG) – records heart’s electrical activity
Holter monitor – continuous heart rhythm monitoring over 24–48 hours
Zio Patch – extended wearable heart rhythm monitor for up to 14 days
Stress testing – evaluates heart rhythm during physical activity
These tools help determine the type, frequency, and severity of arrhythmias for accurate diagnosis.
Treatment is tailored to the type of arrhythmia, symptoms, and overall heart health:
Medical Management – antiarrhythmic medications, heart rate control, or anticoagulants to reduce stroke risk
Lifestyle Optimization – stress reduction, limiting caffeine/alcohol, and maintaining heart-healthy habits
Advanced Interventions – referral for catheter ablation or device therapy when indicated
Our team focuses on symptom relief, risk reduction, and improved quality of life.
