Irregular heartbeats, also known as arrhythmias, occur when the heart beats too fast, too slow, or in an uneven rhythm. This can happen for various reasons, such as stress, caffeine, or underlying health conditions. While some people may not notice any symptoms, others might feel palpitations, dizziness, or even chest pain. Most irregular heartbeats are harmless, but some can lead to serious complications. It's important to consult a healthcare professional if you experience frequent or severe symptoms. They can perform tests to determine the cause and recommend appropriate treatments, ensuring your heart stays healthy and strong.
