What Is an Electrophysiologist? Understanding Heart Arrhythmias and Treatments
An electrophysiologist is a cardiologist who specializes in the electrical signals that control the heartbeat. McLaren Greater Lansing physician Dr. Joseph Banno explains that patients may be referred for unexplained palpitations, fainting or suspected rhythm disorders. Some arrhythmias cause a heartbeat that is unusually fast, slow or irregular.
Evaluating these changes can help determine whether monitoring or treatment is needed.
Atrial fibrillation is one of the better-known heart rhythm disorders. Depending on the diagnosis, clinicians may recommend medication, monitoring or procedures designed to address abnormal electrical activity. Catheter ablation, pacemakers and implanted defibrillators are among the options used for selected conditions. The choice depends on symptoms, heart function and other medical factors.
An occasional sensation of a skipped beat does not always indicate a dangerous problem. However, repeated symptoms or episodes accompanied by dizziness deserve medical attention. Chest pain, severe shortness of breath or fainting may require emergency evaluation. McLaren's August 2026 article explains the role of specialists in diagnosing and treating heart rhythm conditions.
