Cardiac electricity disease, often referred to as cardiac arrhythmias, involves abnormalities in the electrical impulses that control the heart's rhythm. These irregularities can cause the heart to beat too fast, too slow, or erratically, affecting its ability to pump blood effectively. Common types include atrial fibrillation, ventricular tachycardia, and bradycardia. Causes can range from genetic factors and heart disease to electrolyte imbalances and certain medications. Symptoms may include palpitations, dizziness, fainting, and shortness of breath. Treatment options depend on the type and severity of the arrhythmia and may include medications, lifestyle modifications, or medical procedures to correct the abnormal heart rhythm.
