Arrhythmia (heart rhythm disorders)

An arrhythmia is an abnormal or irregular heartbeat caused by a disturbance in the electrical impulses that coordinate your heart rate. This can cause your heart to beat too fast, too slow, or irregularly.

Atrial fibrillation (AFib)

Atrial fibrillation, or AFib, is a type of arrhythmia (abnormal heartbeat) in which the heart’s two upper chambers do not beat in sync with the two lower chambers.

Bradycardia

Bradycardia is a type of abnormal heart rhythm (arrhythmia) in which the heart beats slower than 60 times a minute.

Fainting (syncope)

Syncope, commonly called fainting, is a temporary loss of consciousness caused by a drop in blood flow to the brain.

Heart block

Heart block, also known as atrioventricular (AV) block, is a partial or total blockage of the electrical signal that controls the heartbeat.

Sarcoidosis (Cardiac)

Sarcoidosis causes lumps to form in your heart, lungs, or lymph nodes and can damage these organs.

Short QT syndrome (SQTS)

Short QT syndrome is a disruption of the heart’s electrical activity that causes the recharge time between heartbeats to become too short.

Sick sinus syndrome

Sick sinus syndrome is a malfunction of the heart’s sinus node, which controls heart rhythms. This causes the heart to beat too quickly or too slowly or leads to long pauses between heartbeats.

Tachycardia

Tachycardia is a type of abnormal heart rhythm in which the heart beats much faster than it should while a person is at rest.

Tachycardia-bradycardia syndrome

Tachy-brady syndrome is a type of irregular heartbeat in which the heart fluctuates between beating too quickly and too slowly.

Cardiac Catheterization

Cardiac catheterization is a minimally invasive way to diagnose and treat a variety of heart and vascular conditions by guiding thin, flexible tubes called catheters through blood vessels to problem areas.

Echocardiogram

An echocardiogram uses high-frequency sound waves to create images of your heart.

Electrocardiogram (ECG)

An electrocardiogram, also known as an ECG, measures the heart’s electrical activity.

Electrophysiology testing

Electrophysiology testing is used to evaluate the cause and location of an abnormal heartbeat (known as an arrhythmia).

Event monitors

An event monitor is a small device that records the heart’s electrical activity. It’s similar to an electrocardiogram, but where an electrocardiogram takes place over a few minutes, an event monitor measures heart rhythms over a much longer time.

Holter monitors

A Holter monitor is a small device that records the heart’s electrical activity. It’s similar to an electrocardiogram, but whereas an electrocardiogram records over a few minutes, a Holter monitor records over the course of a day or two.

Tilt table test

Tilt table testing allows your doctor to determine the cause of explained fainting while monitoring changes in your blood pressure and heart rate while tilted at different angles.

Stress Tests

Stress tests are used to assess how your heart works during physical activity. There are several types of stress tests, including treadmill or bike stress tests, nuclear stress tests, stress echocardiograms, and chemically induced stress tests.
