Conditions a Heart Rhythm Specialist May Evaluate
A heart rhythm specialist may evaluate many rhythm-related symptoms, test findings, and device concerns. The exact evaluation depends on symptoms, history, EKG findings, monitor results, risk factors, and clinical need.
Atrial Fibrillation / AFib
AFib is an irregular heart rhythm that may cause palpitations, racing heartbeat, fatigue, shortness of breath, dizziness, or no symptoms at all.
Supraventricular Tachycardia / SVT
SVT can cause episodes of rapid heartbeat, fluttering, chest discomfort, dizziness, or shortness of breath.
Bradycardia
Bradycardia means a slow heart rate. Some patients may need evaluation if symptoms include dizziness, fatigue, fainting, or near-fainting.
Irregular Heartbeat
An irregular heartbeat may require EKG testing, Holter monitoring, event monitoring, or heart rhythm evaluation.
Abnormal EKG
An abnormal EKG may need follow-up with a cardiologist or heart rhythm specialist depending on the pattern and symptoms.
Syncope / Fainting
Fainting or near-fainting may sometimes be related to rhythm issues, but it can have many causes.
Loop Recorder Evaluation
A loop recorder may be considered when symptoms are infrequent and require long-term rhythm monitoring.
Atrial Flutter
Atrial flutter is an abnormal rhythm from the upper chambers of the heart and may require rhythm-focused evaluation.
Ventricular Tachycardia
Ventricular tachycardia is a potentially serious rhythm disorder that requires careful cardiology or electrophysiology evaluation.
Tachycardia
Tachycardia means a fast heart rate. Evaluation depends on symptoms, rhythm type, EKG findings, and overall health.
Palpitations
Palpitations may feel like pounding, fluttering, racing, skipping, or irregular heartbeat.
Abnormal Holter Monitor
Abnormal Holter results may require medication review, rhythm evaluation, AFib evaluation, or electrophysiology consultation.
Pacemaker and ICD Follow-Up
Patients with implanted heart rhythm devices may need ongoing device-related cardiology evaluation.
Ablation Consultation
Cardiac ablation may be discussed for selected rhythm disorders after proper evaluation.
Heart Rhythm Testing at Cardioclinic
Cardioclinic provides diagnostic cardiology testing and heart rhythm evaluation for patients with palpitations, irregular heartbeat, abnormal EKG, suspected AFib, dizziness, fainting, and other cardiovascular symptoms. Testing may vary by provider, location, insurance, scheduling, and clinical need.
EKG / Electrocardiogram
An EKG records a short snapshot of the heart’s electrical activity and may help evaluate abnormal rhythm concerns.
Event Monitoring
Event monitoring may be recommended when symptoms happen less frequently and require longer rhythm tracking.
Stress Testing
Stress testing may be recommended when symptoms occur with exertion or coronary artery disease risk needs further evaluation.
Arrhythmia Care
Arrhythmia diagnosis and management may involve EKG, rhythm monitoring, medication review, and specialty consultation.
Holter Monitoring
Holter monitoring records heart rhythm continuously over a longer period and may help evaluate palpitations or intermittent rhythm symptoms.
Echocardiogram
An echocardiogram evaluates heart structure, pumping function, valves, and chamber size.
AFib Evaluation
Patients with suspected or known atrial fibrillation may need rhythm evaluation, EKG, monitoring, and risk review.
Pacemaker / ICD Evaluation
Pacemaker and ICD concerns may require provider-led rhythm and device-related evaluation when applicable.

Frequently Asked Questions
What is a cardiac electrophysiologist?
A cardiac electrophysiologist is a cardiologist who focuses on the electrical activity of the heart. This specialty evaluates abnormal heart rhythms, also called arrhythmias, including AFib, atrial flutter, SVT, palpitations, irregular heartbeat, abnormal EKG findings, and device-related rhythm concerns.
Is an electrocardiologist the same as a cardiac electrophysiologist?
Electrocardiologist is not the usual medical term. Patients sometimes use this word when they are looking for a cardiologist who evaluates the heart’s electrical system. The more medically accurate term is cardiac electrophysiologist, also known as a heart rhythm specialist.
When should I see a heart rhythm specialist?
You may benefit from heart rhythm evaluation if you have palpitations, racing heartbeat, fluttering, skipped beats, irregular pulse, dizziness with palpitations, fainting or near-fainting, abnormal EKG, suspected AFib, abnormal Holter monitor results, or wearable-device rhythm alerts.
Can an EKG detect AFib or arrhythmias?
An EKG can detect AFib or another arrhythmia if the abnormal rhythm is happening during the test. If symptoms come and go, a Holter monitor or event monitor may be recommended to record the rhythm over a longer period.
What tests are used for palpitations?
Testing for palpitations may include EKG, Holter monitoring, event monitoring, echocardiogram, stress testing, lab review, medication review, and cardiology evaluation depending on symptoms and clinical findings.
Do I need a Holter monitor for irregular heartbeat?
A Holter monitor may be recommended when irregular heartbeat symptoms happen often enough to be captured during short-term continuous monitoring. If symptoms occur less often, an event monitor or longer monitoring option may be considered.
Does Cardioclinic evaluate AFib?
Cardioclinic provides AFib and heart rhythm evaluation for patients with palpitations, irregular heartbeat, abnormal EKG findings, Holter monitor findings, wearable alerts, or known atrial fibrillation. Service availability may vary by provider and location.

What should I do if my Apple Watch says I may have AFib?
A wearable AFib alert should be discussed with a healthcare provider, especially if you have symptoms such as palpitations, chest discomfort, shortness of breath, dizziness, or fainting. A cardiology provider may recommend EKG, Holter monitoring, event monitoring, or AFib evaluation.
When are palpitations an emergency?
Palpitations may need emergency care if they are severe, sudden, associated with chest pain, severe shortness of breath, fainting, weakness, stroke-like symptoms, or symptoms concerning for a heart attack. Call 911 or seek emergency medical care immediately.
