Arrhythmia Q & A

What is arrhythmia?

Arrhythmia is a term used for abnormalities in your heart rate and rhythm. If you have arrhythmia, your heart might beat too fast or too slow, or develop an irregular rhythm.

Your heart's rhythm depends on electrical impulses sent by your body's natural pacemaker — the sinus node. Your heart rate corresponds to the number of impulses the sinus node sends out every minute.

Each electrical signal travels from the top of your heart to the bottom, causing contractions in the muscle that pumps blood through your heart and then around your body. This creates the regular rhythm of a healthy heart.

Disruptions to the electrical impulses and abnormalities that result in arrhythmia can develop for various reasons, including congenital heart conditions, coronary artery disease, and hypertension.

What other symptoms can arrhythmia cause?

Arrhythmia doesn't always cause additional symptoms, but you might experience:

  • Heart palpitations 
  • Dizziness
  • Fainting
  • Chest pain or pressure
  • Shortness of breath
  • Lack of energy

Different types of arrhythmia might cause varying symptoms. At Mission Heart & Vascular, you can benefit from access to cutting-edge diagnostics, including EKG and echocardiogram technology, to determine the cause of your arrhythmia.

How is arrhythmia treated?

The treatment you require for your arrhythmia depends on the reason for your irregular heartbeat. Some of the treatments that could be in the personalized treatment plan Mission Heart & Vascular prepares for you include:

Treating underlying health problems

Conditions like hypertension and diabetes can affect your heart, so it’s vital to properly manage them. You might also benefit from losing weight to reduce the strain on your heart.


Medications called antiarrhythmics change the electrical current in your heart to restore a more regular rhythm. You might also need calcium channel blockers to slow your heart rate, beta blockers to stop adrenaline from causing tachycardia (fast heart rate), or anticoagulants if your arrhythmia increases your risk of blood clots.

Implantable devices

Implantable devices help regulate your heartbeat. Options include pacemakers, defibrillators, and cardiac resynchronization pacemakers.

Catheter ablation

A catheter is a slim tube that fits inside an artery. Using a catheter, your provider at Mission Heart & Vascular can apply heat to the area of heart muscle affected by the arrhythmia. The heat destroys the abnormal tissues, putting a stop to your arrhythmia.

It's also important to regularly undergo screening for other heart problems and make sure you receive treatment for underlying heart conditions.
