Heart arrhythmia is a condition where the heart beats irregularly, either too fast, too slow, or in an uncoordinated manner. This can happen due to various factors, including heart disease, stress, or electrolyte imbalances. While some arrhythmias are harmless, others can lead to serious complications, such as stroke or heart failure.
Symptoms of heart arrhythmia may include palpitations, dizziness, or shortness of breath. Diagnosis typically involves an electrocardiogram (ECG) to monitor the heart's electrical activity. Treatment options vary and may include lifestyle changes, medications, or procedures like cardioversion or ablation.
