For Patients & Families
A plain-language guide to heart rhythm conditions, what to expect from EP procedures, and what questions to ask your doctor — from a practicing cardiac electrophysiologist.
Common Conditions
Your heart has an electrical system that controls every beat. When something disrupts that system — whether it beats too fast, too slow, or irregularly — that's an arrhythmia. Cardiac electrophysiologists (EPs) are the specialists trained to diagnose and treat these conditions.
Most Common Condition
The most common serious heart rhythm disorder — affecting over 12 million Americans. AFib significantly increases stroke risk and requires careful management of two separate goals: stroke prevention and rhythm or rate control. Dr. Luni specializes in AFib management including catheter ablation and Watchman implantation.
Other Heart Rhythm Conditions
Similar to AFib but with a more regular, rapid pattern. Often causes a fluttering feeling in the chest. Highly treatable with catheter ablation.
Episodes of sudden rapid heartbeat that start and stop abruptly. Very common, especially in younger people, and very curable with ablation.
Arrhythmias originating from the ventricles (lower chambers). These range from PVCs — premature beats that are mostly benign — to ventricular tachycardia (VT), which can be more concerning and requires specialist evaluation.
When electrical signals are delayed or blocked, the heart beats too slowly. Often treated with a pacemaker.
Some conditions put patients at risk for sudden cardiac arrest. An ICD can detect and treat dangerous rhythms automatically.
Common Procedures
Be Prepared
Good questions lead to better care. Bring this list to your appointment.
For clinical care, please ask your primary care physician for a referral to Dr. Luni or another electrophysiologist in your area.
