Definition:
Heart rhythm problems (or arrhythmias) occur when the electrical impulses in the heart that coordinate the heartbeats don't function properly, causing the heart to beat too fast, too slow or irregularly.
Diagnosis:
Passive heat monitoring tests such as electrocardiogram, holter monitor, event monitor, and echocardiogram can be done to monitor the heart.
Treatment:
If the patient has received a diagnosis of arrhythmia, treatment may or may not be necessary. Usually, it's needed only if the arrhythmia is causing significant symptoms or if it's putting the patient at risk of a more serious arrhythmia or arrhythmia complication.
Symptoms and Signs:
Often, abnormal heart rhythms cause noticeable signs and symptoms such as: a fluttering in the chest, either a racing or slow heartbeat, chest pain, shortness of breath, lightheadedness, dizziness, and fainting or syncope.
Causes:
Common causes of arrhythmias, or conditions that can result to arrhythmias, include heart disease, high blood pressure, diabetes, smoking, excessive use of alcohol or caffeine, drug abuse, and stress. Over-the-counter medications, prescription medications, dietary supplements and herbal remedies also can lead to arrhythmias in some people.
