You may have heard this if you listened with a stethoscope or with your ear on someone's chest. After your atria pump blood into the ventricles, the valves between the atria and ventricles close to prevent backflow.

Feeling faint 4. Fati...
Any condition that compromises your heart tissue or changes the conduction pathways that control the normal rhythmic pattern of your heartbeat can cause an arrhythmia. The most common causes of an abnormal heartbeat are: 1. Heart disease 2. Electrolyte imbalances in your blood 3. Structural abnormalities of the heart 4. Infection 5. Abnormal electr...
Most people don’t experience an abnormal heart rhythm during a medical visit, but taking a detailed medical history (asking you about your medications, lifestyle habits, and past medical history) and performing a focused physical exam (listening to your heart with a stethoscope and measuring your blood pressure and pulse) can help your healthcare p...
There is no one-size-fits-all approach to treating arrhythmia, and a treatment that works for one person may not work for another person. The most effective way to manage your condition is to diagnose the type of arrhythmia and resolve the underlying cause of your abnormal heartbeat. The goals of arrhythmia treatment are to: 1. Minimize stroke risk...
If your abnormal heartbeat is accompanied by severe chest pain, shortness of breath, light-headedness, feeling faint, or does not go away with your typical treatment, then seek immediate medical attention as untreated arrhythmia can lead to heart failure and sudden cardiac arrest. In rare cases, an arrhythmia may be severe enough to disrupt the hea...
An abnormal heartbeat (arrhythmia) occurs when the electrical signals cannot travel smoothly throughout the heart, causing your heart to quiver and beat out of rhythm.
An abnormal heartbeat should be a cause for concern. If your abnormal heartbeat is accompanied by severe chest pain, shortness of breath, light-headedness or feeling faint, or if it does not go away with your typical treatment, it is important to seek immediate medical attention. A healthcare provider can help determine the cause and subsequent tre...
The heart beats because of a small electrical current generated by the the cardiac conduction system. The cardiac conduction system is a group of muscle cells in the walls of the heart. It's comprised of five major components:

Mar 12, 2024 · Overview. What is heart rate? Your heart rate is the number of times your heart beats in a minute. Your body automatically controls your heartbeat to match whatever you’re doing or what’s happening around you. That’s why your heartbeat gets faster when you’re active, excited or scared. And it drops when you’re resting, calm or comfortable.
A "beat" is a contraction of the heart. Each time a section of the heart contracts, it forces blood from one point to another. It goes like this: Heart Pictures. When blood returns to the heart from the rest of the body, it flows into the right atrium (1). The blood has been supplying oxygen throughout the body and needs a refill.
Oct 13, 2023 · A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. A heart arrhythmia occurs when the electrical signals that tell the heart to beat don't work properly. The heart may beat too fast or too slow. Or the pattern of the heartbeat may be inconsistent. A heart arrhythmia may feel like a fluttering, pounding or racing heartbeat.
