The <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/heart.html/">heart</a> can beat irregularly, too quickly (<a href="https://kidshealth.org/ws/RadyChildrens/en/parents/az-tachycardia.html/">tachycardia</a>), or too slowly (bradycardia).</p> <h3>More to Know</h3> <p>An irregular heart rhythm has been described as a heart that flutters, races, or skips a beat. Other symptoms can include lightheadedness, dizziness, shortness of breath, chest pain, sweating, and fainting. Some people experience no symptoms at all and are surprised when dysrhythmia is detected at a routine doctor's visit.</p> <p>Many factors can lead to dysrhythmia, including heart attack, heart and valve disorders, imbalances in blood chemistry and hormone levels, <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/hypertension.html/">high blood pressure</a>, smoking, caffeine, substance abuse, and even some medications.</p> <h3>Keep in Mind</h3> <p>Dysrhythmias are often harmless, but can be an indication of a much larger problem (the heart not adequately pumping blood to vital organs), which can be life threatening. If you suspect dysrhythmia, consult your doctor for testing and treatment.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
