Understanding arrhythmia treatment begins with understanding the condition itself. An arrhythmia is any disruption to the heart’s normal electrical rhythm, and for many patients in Phoenix and the surrounding area, receiving an accurate diagnosis is the first step toward feeling informed and confident about their care. Whether you have been told your heart beats too fast, too slowly, or irregularly, a range of well-established treatment options exists to help manage your condition. This guide is designed for patients who are researching their options and want clear, evidence-based information.

Understanding Arrhythmia: Types, Causes, and How They Are Diagnosed
Arrhythmias are classified by where in the heart they originate and how they affect heart rate. Supraventricular arrhythmias begin above the ventricles and include conditions such as atrial fibrillation, atrial flutter, and supraventricular tachycardia (SVT). Ventricular arrhythmias originate in the lower chambers and may require more urgent evaluation. Bradyarrhythmias describe rhythms that are too slow, while tachyarrhythmias describe rhythms that are too fast.
Common Causes of Arrhythmia
Many factors may contribute to the development of an arrhythmia. These include coronary artery disease, high blood pressure, thyroid disorders, electrolyte imbalances, sleep apnea, and certain medications. In some cases, genetic conditions such as Long QT Syndrome or Wolff-Parkinson-White (WPW) Syndrome are the underlying cause. In our practice, we find that a thorough evaluation of contributing factors leads to a more targeted and effective treatment plan.
Diagnostic Tools
Accurate arrhythmia diagnosis relies on a combination of clinical evaluation and specialized cardiac testing. An electrocardiogram (ECG) is typically one of the first tools used to capture the heart’s electrical activity. Depending on the findings, additional monitoring or advanced imaging may be recommended. At Heart Rhythm Institute of Arizona, Dr. John Beshai also uses intracardiac echocardiography (ICE) during complex procedures to provide real-time, high-resolution imaging that enhances procedural precision and patient safety.
Arrhythmia Treatment Options: From Medications to Advanced Procedures
Arrhythmia treatment is not one-size-fits-all. The most appropriate approach depends on the type of arrhythmia, its severity, the presence of underlying heart conditions, and your personal health goals. Treatment plans may range from lifestyle modifications and medication management to advanced procedural interventions.
Medications
Antiarrhythmic medications may help regulate heart rhythm or control heart rate in patients with certain conditions. Blood thinners are often recommended for patients with atrial fibrillation to reduce the risk of stroke. Medication regimens are tailored to each patient and monitored over time, as responses can vary and adjustments are sometimes necessary.
Catheter Ablation
Catheter ablation is a minimally invasive procedure in which a thin, flexible catheter is guided to the area of the heart producing abnormal electrical signals. That tissue is then modified using either heat energy, known as radiofrequency ablation, or cold energy, known as cryoablation. Research suggests that ablation may offer significant long-term rhythm control for many patients with atrial fibrillation and other arrhythmias. Dr. Beshai offers both radiofrequency cardiac ablation and cryoablation, as well as the advanced approach known as hybrid AFib therapy, which combines surgical and catheter-based techniques for more complex cases.
Implantable Devices
For patients whose arrhythmia places them at risk for cardiac arrest or whose heart beats too slowly without support, implantable devices may be recommended. Pacemakers help regulate a slow or irregular heartbeat, while implantable cardioverter defibrillators (ICDs) are designed to detect and interrupt dangerous ventricular arrhythmias. The WATCHMAN device is another option for eligible patients with AFib who need an alternative to long-term anticoagulation therapy. Individual results and device suitability vary, and a thorough candidacy evaluation is always conducted before any recommendation is made.
Living With an Arrhythmia: What to Expect From Ongoing Care
For many patients, an arrhythmia diagnosis is the beginning of a long-term care relationship rather than a single event. Understanding what ongoing management involves can help reduce uncertainty and support informed decision-making.
Monitoring and Follow-Up
Patients undergoing arrhythmia treatment typically have scheduled follow-up visits to assess how well the chosen approach is working. Remote cardiac monitoring devices may be used between office visits to track rhythm patterns over time. These tools allow for timely adjustments to treatment when needed, without requiring frequent in-person visits for every change in symptoms.
Lifestyle Considerations
Lifestyle factors can have a meaningful impact on arrhythmia management. Regular physical activity, blood pressure control, maintaining a healthy weight, limiting alcohol consumption, and addressing sleep apnea may all contribute to better rhythm outcomes. Patients are encouraged to discuss any planned changes to their exercise routine with their provider. For athletes and highly active individuals, specialized evaluation such as an athlete physical may be appropriate to ensure that activity levels are safe given the individual’s cardiac profile.
When to Seek Care Promptly
Some arrhythmia symptoms warrant prompt evaluation. These include new or worsening palpitations, lightheadedness, shortness of breath at rest, chest discomfort, or episodes of syncope (fainting). While not every irregular heartbeat is an emergency, these symptoms are worth discussing with a cardiac electrophysiologist to determine whether further evaluation is needed. Early assessment generally leads to more options and more straightforward treatment paths.

Frequently Asked Questions About Arrhythmia Treatment
What is the difference between an arrhythmia and atrial fibrillation?
Atrial fibrillation, or AFib, is a specific type of arrhythmia and one of the most commonly diagnosed heart rhythm disorders. Arrhythmia is a broader term that describes any abnormality in the heart’s electrical rhythm, including conditions that are too fast, too slow, or irregular. AFib falls under the category of supraventricular arrhythmias and involves disorganized electrical activity in the upper chambers of the heart. A cardiac electrophysiologist can help determine which type of arrhythmia you may have.
How do I know if I need ablation or just medication for my arrhythmia?
The decision between medication management and a procedure such as catheter ablation depends on factors including the type and frequency of your arrhythmia, how well you tolerate symptoms, your overall health, and your personal preferences. Some patients do well with medication alone, while others may benefit from a more definitive approach. Research suggests that ablation may offer better long-term rhythm control for certain conditions. A thorough evaluation with a specialist helps clarify which path may be most appropriate. Individual results vary.
Is arrhythmia treatment covered by insurance in Arizona?
Many arrhythmia treatments, including diagnostic testing, medication management, catheter ablation, and device implantation, are typically covered by major insurance plans when medically indicated. Coverage details depend on your specific plan, diagnosis, and the procedures recommended. Dr. Beshai’s involvement with the Medicare Evidence Development and Coverage Advisory Committee reflects a commitment to ensuring that patients have access to the most clinically appropriate and evidence-supported treatment options. Our team can assist with insurance questions during the scheduling process.
Can arrhythmias be related to other heart conditions?
Yes. Arrhythmias can occur alongside or as a result of other cardiac conditions, including congestive heart failure, hypertrophic obstructive cardiomyopathy (HOCM), and cardiac sarcoidosis, among others. This is one reason why a comprehensive evaluation is important. Understanding any underlying structural or systemic conditions helps ensure that arrhythmia treatment addresses the full picture of a patient’s heart health rather than symptoms alone.
How long does recovery take after a cardiac ablation procedure?
Most patients are able to return to light daily activities within a few days following catheter ablation, though individual recovery timelines vary. Strenuous exercise and physically demanding work may need to be limited for a short period as directed by your care team. Some patients notice an initial period of irregular beats in the weeks following the procedure as the heart adjusts; this is generally expected and does not necessarily indicate that the procedure was unsuccessful. Your provider will outline specific recovery guidance based on your procedure and overall health.
