Atrial fibrillation, often called AFib, is a common irregular heart rhythm. A cardiologist or cardiac electrophysiologist — a heart rhythm specialist — may evaluate AFib and discuss care options that depend on the individual.
An arrhythmia is a heart rhythm that is too fast, too slow, or irregular. A heart rhythm specialist may evaluate these patterns and discuss next steps based on your symptoms and test results.
Supraventricular tachycardia, often called SVT, is a group of fast heart rhythms that start above the ventricles. A heart rhythm specialist may evaluate possible SVT when symptoms or test results raise that question.
Heart palpitations are a feeling that the heart is racing, fluttering, pounding, or skipping beats. They are a symptom, not a diagnosis. A cardiologist or heart rhythm specialist may evaluate palpitations to look for an arrhythmia or other explanation.
Heart failure means the heart is not pumping as effectively as it should. Some people with heart failure also have heart rhythm disorders. This page is educational and does not mean every patient with heart failure needs electrophysiology care.
Atrial flutter is a rapid heart rhythm that starts in the atria, the upper chambers of the heart. Unlike atrial fibrillation, the heartbeat in flutter is typically regular. A heart rhythm specialist in Reseda may evaluate possible flutter when symptoms or an EKG raise that question.
Ventricular tachycardia, often called VT, is a rapid heart rhythm that originates in the ventricles, the lower chambers of the heart. A cardiac electrophysiologist may evaluate possible VT when symptoms, an EKG, or hospital monitoring raise that concern.
Ventricular fibrillation, often called VF, is a very fast, irregular rhythm in the ventricles. The heart cannot pump effectively. VF is a medical emergency. This page is educational and is not a substitute for calling 911.
Syncope is a sudden loss of consciousness with a typically rapid recovery. It can be harmless or related to a serious heart problem. People who faint should seek medical attention. A heart rhythm specialist may evaluate whether an arrhythmia contributed.
Bradycardia means the heart is beating too slowly. Sinus bradycardia is often described as a rate under 60 beats per minute. Not every slow pulse needs treatment. A physician determines whether evaluation or pacing should be discussed.
In sick sinus syndrome, the SA node does not reliably perform its role as the heart’s natural pacemaker. The heart may beat too slowly, pause, or sometimes alternate between slow and fast rhythms. A heart rhythm specialist may evaluate this pattern after symptoms or monitoring.
Wolff-Parkinson-White syndrome involves an extra electrical pathway that can let signals bypass the normal route through the AV node. That extra pathway can cause very fast heart rates. A heart rhythm specialist may evaluate WPW after an EKG or symptoms of SVT.
Heart block, or atrioventricular (AV) block, is a delay or interruption of the electrical signal as it travels from the atria to the ventricles. The heart may beat too slowly. A physician classifies the type of block and decides whether treatment is needed.
A premature ventricular contraction is an extra beat that starts in a ventricle before the normal signal arrives. Many people feel a skip or pause. PVCs are common. A physician decides whether they need further evaluation.
Sudden cardiac arrest occurs when the heart abruptly stops beating and circulation stops. It is different from a heart attack, though heart disease can raise risk. This page is educational. If someone collapses, call 911.
Long QT syndrome is a condition in which the heart’s electrical recovery after each beat is delayed. That delay can raise the risk of a dangerous ventricular rhythm. A heart rhythm specialist may evaluate a prolonged QT interval found on an EKG or after symptoms such as fainting.
Atrioventricular nodal re-entrant tachycardia, often called AVNRT, is a type of SVT. Recovered Cardiac Rhythm Specialists education described it as the second most common SVT. A heart rhythm specialist may evaluate possible AVNRT when a fast rhythm starts above the ventricles.
Atrioventricular reciprocating tachycardia, often called AVRT, is a type of SVT that uses an extra electrical pathway around the AV node. Recovered practice education distinguished it from AVNRT. A cardiac electrophysiologist may evaluate this pattern when symptoms or testing raise that question.
Premature atrial contractions, often called PACs, are extra atrial beats that occur earlier than expected and briefly interrupt the heart rhythm. Recovered Cardiac Rhythm Specialists education described them as common. They are a finding, not a complete diagnosis.
The original Cardiac Rhythm Specialists conditions library included aortic valve disease because valve problems can affect heart rhythm and pumping. This page recovers that education. It is not a statement that valve surgery is offered through this office.
The original conditions library also explained mitral valve disease. Recovered text described mitral stenosis and mitral regurgitation. This page preserves that education. It does not advertise valve surgery.
