An arrhythmia is a disorder of the heart’s electrical system that causes the heart to beat too fast, too slow, or irregularly. At Heart & Vascular Specialists DFW, we provide comprehensive arrhythmia management focused on accurate diagnosis, symptom relief, and long-term heart rhythm control.
Our cardiology team creates personalized treatment plans based on your symptoms, overall heart health, and lifestyle.
We diagnose and manage a wide range of heart rhythm disorders, including:
Atrial fibrillation (AFib)
Atrial flutter
Supraventricular tachycardia (SVT)
Ventricular arrhythmias
Bradycardia (slow heart rate)
Tachycardia (fast heart rate)
Premature atrial or ventricular contractions (PACs/PVCs)
Arrhythmias can cause noticeable symptoms or may be discovered during routine testing. Common symptoms include:
Palpitations or fluttering in the chest
Irregular or rapid heartbeat
Dizziness or lightheadedness
Shortness of breath
Chest discomfort
Fatigue or weakness
Fainting or near-fainting episodes
If you experience any of these symptoms, a cardiac evaluation is recommended.
We use advanced diagnostic testing to evaluate heart rhythm abnormalities, including:
Electrocardiogram (EKG/ECG)
Ambulatory heart monitoring (Holter monitor, event monitor)
Stress testing
Echocardiography
Implantable loop recorders, when appropriate
These tools help determine the type, frequency, and severity of arrhythmias.
Treatment depends on the type of arrhythmia, symptoms, and underlying heart conditions. Management may include:
Antiarrhythmic medications, heart rate control drugs, or blood thinners to reduce stroke risk.
Addressing triggers such as high blood pressure, sleep apnea, obesity, caffeine use, and stress.
Cardioversion to restore normal heart rhythm when appropriate.
Evaluation and follow-up for pacemakers or implantable cardiac devices.
Referral for advanced electrophysiology procedures such as catheter ablation when indicated.
Untreated arrhythmias can increase the risk of complications such as stroke, heart failure, or sudden cardiac events. Early diagnosis and proper management help reduce risks and improve quality of life.
During your arrhythmia evaluation, you can expect:
A detailed review of symptoms and medical history
Heart rhythm testing or monitoring
Discussion of treatment options
A personalized care plan focused on safety and symptom relief
