A cardiac electrophysiology expert decides whether a heart rhythm problem was evaluated and treated the way a reasonably careful specialist would have done it, and whether a device or procedure caused harm. Most cases involve catheter ablation, a pacemaker or an implantable defibrillator. This page covers heart rhythm disorders and their procedures. General heart disease belongs to a cardiologist, coronary stents to an interventional cardiologist, and open repair of a complication to a cardiothoracic surgeon.
The expert reads procedure reports, intracardiac tracings, device interrogations, ECGs and monitor strips, imaging, anticoagulation records, consent forms and the follow-up calls and visits after discharge. Device memory is a powerful record: an interrogation can show what rhythm occurred and how the device responded, so it should be downloaded and preserved early.
Ablation for atrial fibrillation is a common procedure with serious known risks. One review reports complication rates cited in the range of 3.5 to 5 percent, with the majority consisting of cardiac tamponade, vascular complications and thromboembolic events 1. Another says complications have decreased as technology and knowledge have evolved, but that the risks of tamponade, thromboembolic complications, esophageal injury and pulmonary vein stenosis may still be formidable 2.
So the case rarely turns on the bare fact of a complication. It turns on selection, technique, recognition and response:
This is the complication that most clearly puts the follow-up care on trial. One case series calls it probably the most catastrophic complication of radiofrequency ablation, with a mortality rate that might exceed 80 percent in severe cases 3. The onset is delayed, usually several days or weeks after the procedure, which impedes prompt diagnosis 3. Symptoms such as fever, chills, cough or neurologic complaints are far from specific 3. A patient may go to a local emergency department weeks later and be sent home.
That makes discharge instructions, phone triage and what the emergency physician was told central to the case. The expert asks whether the patient was warned, whether the correct imaging was ordered and whether anyone did an endoscopy, which can make the injury worse. The authors say there is no validated method to prevent this complication 3, and that fact matters in deciding whether the injury itself suggests negligence.
Device claims divide into implant technique, programming and the device itself. NHLBI describes defibrillators as devices that apply an electric charge or current to the heart to restore a normal heartbeat 4. Complaints include lead perforation, pocket infection, inappropriate shocks and failure to deliver therapy. The interrogation file should show what happened, and the device's model and lead history should be checked against any recall or advisory.
Product claims bring in federal reporting rules. Under 21 CFR Part 803, device user facilities must report deaths and serious injuries that a device has or may have caused or contributed to, and manufacturers must also report certain device malfunctions 5. Such reports can be useful leads, though they do not prove a defect. Preemption can limit a claim against the maker of a high-risk device, so counsel should raise it early.
Look for a physician with fellowship training and board certification in clinical cardiac electrophysiology who performs the procedure regularly and manages its complications. Experience with the specific ablation energy or device matters, since these technologies differ. A claim against an emergency physician or a general cardiologist may call for a same-field witness on the standard of care, with the electrophysiologist addressing cause.
One case series says atrio-esophageal fistula after ablation has a mortality rate that might exceed 80 percent in severe cases, and that its delayed onset impedes prompt diagnosis.

FAQ
Look for fellowship training and board certification in clinical cardiac electrophysiology, with regular performance of the procedure and management of its complications. A claim against another specialty may need a same-field witness on the standard of care.
Not by itself. Reviews describe tamponade, stroke and esophageal injury as known risks. The case turns on patient selection, technique, recognition and response.
One case series says mortality might exceed 80 percent in severe cases. Onset is usually several days or weeks after the procedure, and symptoms are not specific, so discharge instructions and later triage matter.
An interrogation can show the rhythm and how the device responded. It should be downloaded and preserved early, and the model and leads checked against any advisory.
No. Reports under 21 CFR Part 803 can be useful leads, but they do not prove what caused an event. Preemption can also limit claims against makers of high-risk devices.
In general, cardiac electrophysiology expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are experience, the procedure or device at issue, the volume of tracings and device data, record review and the amount of testimony. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
