Heart rhythm concerns can be confusing because they often come and go, and many patients are unsure what type of specialist handles these issues. At the Heart Rhythm Institute of Arizona, care is centered around the expertise of Dr. John F. Beshai, an electrophysiologist who specializes in diagnosing and treating problems with the heart’s electrical system. This blog explains what an electrophysiologist does and why their training is important for patients experiencing irregular heartbeats.
What an Electrophysiologist Focuses On
Unlike general cardiologists who oversee a wide range of heart conditions, electrophysiologists concentrate specifically on the electrical signals that control the heartbeat. These electrical patterns keep the heart beating steadily and ensure each chamber works in sync. When something disrupts these signals, patients may notice palpitations, sudden racing or slowing of the heartbeat, or unexplained dizziness.
An electrophysiologist is trained to study these disruptions in detail and determine whether the rhythm issue is harmless, needs monitoring, or requires treatment.
How Heart Rhythm Problems Are Evaluated
Diagnosis begins with a careful review of symptoms and heart rhythm testing. Dr. Beshai uses tools designed to detect irregular electrical activity, including:
- Electrocardiograms and wearable monitors that track the heart over time
- Advanced rhythm studies that map how electrical signals travel
- Targeted imaging when structure and function need further evaluation
These tests help identify not just the type of arrhythmia, but also where it starts and why it occurs. This level of detail is essential for choosing the right treatment.
Treatment Options Guided by an Electrophysiologist
Because every arrhythmia behaves differently, treatment plans are individualized. Electrophysiologists manage a range of therapies, such as:
Catheter Ablation
A minimally invasive procedure that treats tissue responsible for triggering irregular signals.
Pacemakers
Devices that help regulate slow or inconsistent rhythms.
Implantable Defibrillators
Used for patients at risk of dangerous arrhythmias to monitor and correct the heartbeat when needed.
Medication and Follow-Up
Some rhythm issues improve with medication and ongoing monitoring.
The goal is always to restore stability, reduce symptoms, and support heart health.
When to Consider Seeing an Electrophysiologist
Patients are typically referred when rhythm symptoms persist, when initial testing shows electrical abnormalities, or when specialized procedures may be helpful. Some patients also see an electrophysiologist for long-term device management or second opinions about rhythm treatment options.
