What is an arrhythmia? 

An arrhythmia is an abnormal heart rhythm that occurs when your heart beats too quickly, too slowly, or irregularly. Your heart relies on electrical signals to maintain a steady rhythm and pump blood effectively throughout your body. When those signals don’t work properly, your heartbeat may become disrupted.

Some arrhythmias are harmless and may not require treatment, while others can affect your heart’s ability to function properly and may increase your risk of complications. 

Different types of arrhythmias can affect your heart in different ways, making it important to have any concerning symptoms evaluated.

How does arrhythmia affect your heartbeat?

When you have an arrhythmia, your heart may not beat in a normal pattern. A fast heartbeat, known as tachycardia, can make your heart work harder. A slow heartbeat, called bradycardia, may prevent your body from receiving enough oxygen-rich blood.

An irregular heartbeat can affect how efficiently your heart pumps blood. In some cases, this may lead to problems such as reduced circulation, dizziness, or an increased risk of blood clots, depending on the type of arrhythmia.

What causes an arrhythmia?

Arrhythmias can develop for several reasons. Sometimes they occur because of changes in the heart’s electrical system. Other times, certain health conditions or lifestyle factors may contribute to an abnormal heartbeat.

Common causes and risk factors include:

• Heart disease or previous heart damage
• High blood pressure
• Thyroid disorders
• Electrolyte imbalances
• Certain medications
• Excessive alcohol use
• Smoking
• Stress
• Sleep apnea

Aging can also be a factor.

What symptoms can an arrhythmia cause?

Some people with an arrhythmia do not notice any symptoms. Others may experience changes that are easy to overlook or may come and go.

Possible symptoms include:

• Heart palpitations or a fluttering sensation
• A racing or slow heartbeat
• Dizziness or lightheadedness
• Shortness of breath
• Fatigue
• Chest discomfort
• Fainting

If you experience severe chest pain, difficulty breathing, fainting, or sudden weakness, seek emergency medical care.

How is arrhythmia diagnosed and treated?

At AssociatesMD, your healthcare provider reviews your symptoms, medical history, and risk factors before recommending testing. They may use an electrocardiogram (EKG), heart monitor, blood tests, or other diagnostic tools to evaluate your heart rhythm.

Treatment options may include lifestyle changes, medications, procedures to restore a normal rhythm, or devices that help regulate your heartbeat.
