Overview

Arrhythmias, also known as heart rhythm disorders, are conditions in which the heart does not beat in a steady, regular way. The heart rate could speed up, slow down, or become uneven. Normally, the heart's electrical system is well-coordinated and keeps everything in sync. When this system stops working, the timing of each beat changes. This can make it harder for blood to flow through the body. Some changes in rhythm aren't dangerous and don't last long, but others are more serious and require medical attention. The experience is very different for everyone; some people hardly notice it, while others find it very uncomfortable.

Symptoms
Palpitations, or the feeling that your heart is racing, fluttering, or skipping beats, are a common symptom. Some people might feel lightheaded, dizzy, or more tired than usual. You may have trouble breathing or feel chest pain, especially if your heart isn't pumping well. In more obvious cases, people may faint or feel like they are going to faint. But not everyone has symptoms, and some rhythm disorders are found during routine tests.

Causes
Many things can cause heart rhythm problems. They are often caused by underlying heart problems like coronary artery disease and heart failure. The heart's rhythm can also be affected by high blood pressure, thyroid problems, and electrolyte imbalances. Stress, too much caffeine, alcohol, smoking, or not getting enough sleep are all things that can set off episodes. Some medicines and infections can also mess with the heart's electrical signals. Sometimes, there is no clear reason for it.

Diagnosis
An ECG, which records the heart's electrical activity, is usually the first step in diagnosis. If the irregular rhythm doesn't show up during the test, doctors may suggest monitoring it for a longer period with a Holter device or a similar device. Blood tests may be performed to detect underlying conditions, and imaging tests, such as echocardiography, may be used to assess the heart's structure and function.

Treatment
The kind and severity of the rhythm disorder will determine how it is treated. For mild cases, just keeping an eye on things or making lifestyle changes may be enough. People often take drugs to bring their heart rate back to normal or control it. In some cases, doctors may suggest procedures such as catheter ablation or the placement of a device, such as a pacemaker. Most people can handle their symptoms well and go about their normal daily lives with the right care and regular check-ups.
