What are Heart Rhythm Disorders?
Heart rhythm disorders, also called arrhythmias, happen when the heart’s electrical system causes it to beat too fast, too slow, or irregularly. While many irregular heartbeats are harmless, some can signal a more serious problem—especially when they occur alongside other heart conditions. Understanding how the heart’s rhythm works is an important first step in recognizing symptoms, knowing when to seek care, and learning about treatment options.
