Hello, I'm an expert in the field of cardiology with a focus on heart rhythm disorders. It's important to understand that the heart is a muscle that beats in a regular pattern under normal circumstances. However, some degree of variability in heart rate is normal, especially in response to physical activity, stress, or certain medications. But irregular heartbeats, also known as arrhythmias, can occur and may be a cause for concern depending on their nature and frequency. An irregular heartbeat can be harmless in some cases, such as when it's caused by something like exercise or caffeine. However, it can also be a sign of an underlying heart condition, which may require medical attention. Some common types of arrhythmias include atrial fibrillation, ventricular tachycardia, and supraventricular tachycardia. These can range from mild to life-threatening, depending on the specific type and the individual's health status. It's crucial to consult with a healthcare professional if you're experiencing an irregular heartbeat, especially if it's accompanied by symptoms like dizziness, shortness of breath, chest pain, or fainting. A doctor can perform tests such as an EKG to diagnose the issue and determine the appropriate course of treatment. In summary, while some irregular heartbeats can be normal, others may indicate a serious health issue. It's always best to seek medical advice to understand the cause and ensure proper management. read more >>

It just means it's out of its normal rhythm. It may feel like your heart skipped a beat, added a beat, is "fluttering," or is beating too fast (which doctors call tachycardia) or too slow (called bradycardia). Or, you might not notice anything, since some arrhythmias are "silent."read more >>
