Arrhythmia
Overview
Arrhythmia is a condition that affects the rhythm of your heartbeat. Your heart may beat too fast, too slow, or in an irregular pattern. If you have it, it does not always mean something serious is happening, but it is important to understand what type of arrhythmia you have and how it affects you.
Your heart normally beats in a steady, regular rhythm to circulate blood throughout your body. In arrhythmia, this rhythm is disrupted. Some types are mild and may come and go without causing harm, while others can affect how well your heart pumps blood.
You may notice symptoms occasionally, or not at all. With proper evaluation and monitoring, most arrhythmias can be managed effectively, helping you stay safe and maintain your normal activities.
Symptoms
Symptoms can vary depending on the type of arrhythmia. You may experience:
- A sensation of a racing, fluttering, or pounding heartbeat
- Feeling like your heart is skipping beats
- Dizziness or lightheadedness
- Shortness of breath

- Chest discomfort
You may not notice any symptoms and only discover an arrhythmia during a routine check.
