How are heart rhythm disorders diagnosed?
To diagnose a heart rhythm disorder, a healthcare provider may perform a physical examination, review the patient's medical history, and order tests such as an electrocardiogram (ECG or EKG), Holter monitor, event monitor, echocardiogram, stress test, or electrophysiology study.
What are the symptoms of a heart rhythm disorder?
Symptoms of a heart rhythm disorder can vary depending on the specific arrhythmia and its severity. Common symptoms include palpitations (awareness of the heartbeat), rapid or irregular heartbeat, dizziness, fainting (syncope), chest discomfort, shortness of breath, and fatigue. However, some people with arrhythmias may not experience any noticeable symptoms.
What are abnormal heart rhythms?
Abnormal heart rhythms are called arrhythmias. These can manifest as a heartbeat that is too fast (tachycardia), too slow (bradycardia), or irregular. Some common arrhythmias include atrial fibrillation, atrial flutter, ventricular tachycardia, and ventricular fibrillation.
