Heart issues are terrifying. Honestly, there is no other way to put it. When your chest starts fluttering like a trapped bird or your heart skips a beat for no reason, you don't just want a doctor; you want the best person in the room. In Greenville, North Carolina, that person is often Dr. David Frazier.
He isn't just your run-of-the-mill cardiologist. Dr. Frazier is a clinical cardiac electrophysiologist. Basically, he’s the "electrician" for the heart. While a standard cardiologist might look at the plumbing—the blood flow and the valves—Dr. Frazier focuses on the wiring that makes the whole thing pump in the first place.
The Mayo Clinic Pedigree in Eastern North Carolina
You don't just wake up and become an expert in heart rhythms. It takes decades. Dr. Frazier graduated from the Mayo Clinic in 1994. If you know anything about medicine, you know the Mayo Clinic is essentially the gold standard.
With over 30 years of experience, he’s seen it all. He isn't some new kid on the block trying out the latest gadgets. He’s a veteran who has spent thousands of hours in the "EP lab" (electrophysiology lab) fixing hearts that have lost their rhythm.
He is currently affiliated with ECU Health Medical Center and leads Heart Rhythm Associates in Greenville.

What Does an Electrophysiologist Actually Do?
Think of your heart as a house. If the pipes burst, you call a plumber. If the lights are flickering or the breaker keeps tripping, you call an electrician.
Dr. David Frazier deals with the "flickering lights" of the human body. He specializes in:
- Atrial Fibrillation (AFib): This is the big one. It’s a quivering or irregular heartbeat that can lead to blood clots, stroke, or heart failure.
- Cardiac Ablations: This is a procedure where he actually scars tiny areas of heart tissue to block irregular electrical signals. It sounds scary, but for many patients, it’s a total life-changer.
- Pacemakers and ICDs: He’s the guy who implants and manages the devices that keep your heart beating at the right speed.
- Tachycardia: When your heart decides to run a marathon while you're just sitting on the couch.
Patients in Greenville talk a lot about his "bedside manner." It’s a bit of a cliché, but in his case, it seems to be true. One patient mentioned that after years of ER visits and "mystery" heart spikes, Frazier was the first person to actually explain why it was happening.
The Reality of Waiting Times
Let’s be real for a second. If you go see a specialist this high-profile, you're probably going to wait.

A quick look at recent patient feedback from January 2026 shows a recurring theme: people love Dr. Frazier, but they don't always love the lobby. Some patients have reported waiting over an hour past their appointment time.
Is it worth it? Most say yes. When you’re dealing with a doctor who treats complex arrhythmias and performs life-saving ablations, they aren't exactly punching a time clock. They stay with the patient who needs them. If you’re that patient one day, you’ll appreciate the extra twenty minutes he spends with you, even if it makes him late for the next person.
Why Greenville?
Greenville has become a massive medical hub for Eastern North Carolina. Between ECU Health and private practices like Heart Rhythm Associates (located at 2340 Hemby Lane), the city pulls in patients from all over the coast.
Dr. Frazier has been a fixture here for a long time. He’s board-certified in Clinical Cardiac Electrophysiology, which is a specific sub-specialty of internal medicine. It's a high-stress, high-precision field. One wrong move during an ablation and things go south quickly. That’s why his 30+ years of experience matter so much.

What Most People Get Wrong About Heart Rhythms
A lot of people think a "palpitation" is just stress. "Oh, I’m just caffeinated," they say.
Sometimes that’s true. But Dr. Frazier’s work often reveals underlying issues like Paroxysmal Atrial Fibrillation or heart blockages that don't show up on a basic EKG. Honestly, if you're feeling "flutters" more than once a week, it’s not just the coffee.
One of the coolest things he’s doing lately? Helping patients integrate modern tech. Recent reports show his staff helping older patients set up AFib alarms on their Apple Watches. It’s a mix of old-school Mayo Clinic expertise and 2026 wearable tech.
Actionable Steps if You're Seeing Dr. Frazier
If you’ve been referred to Dr. David Frazier in Greenville, NC, don't just show up and hope for the best. Be prepared.
- Bring Your Data: If you use an Apple Watch, Fitbit, or KardiaMobile device, bring the printouts or show the app. Electrophysiologists love data points.
- Clear Your Schedule: Don't book a lunch meeting right after your appointment. As mentioned, wait times can be unpredictable because he handles emergencies.
- Ask About the "Watchman": If you have AFib but can't take blood thinners, ask him about the Watchman device. He’s one of the specialists in the region who deals with these types of implantable alternatives.
- Verify Your Insurance: He takes the big ones—Blue Cross Blue Shield, UnitedHealthCare, Cigna—but always call the Hemby Lane office first to be sure.
Fixing a heart rhythm isn't just about living longer; it's about not being afraid of your own chest. Whether it's a routine pacemaker check or a complex ablation, Dr. Frazier has built a reputation in Greenville as the guy who can actually find the "short circuit" and fix it for good.
