Upper heart chamber not working

If the upper heart chamber, known as the atrium, is not functioning properly, it can lead to various heart conditions such as atrial fibrillation or atrial flutter. These issues may result in inefficient blood flow, increased risk of blood clots, and symptoms like palpitations, shortness of breath, or fatigue. Treatment options may include medications, lifestyle changes, or procedures like cardioversion or ablation, depending on the severity of the condition. It's essential to consult a healthcare professional for a proper diagnosis and management plan.
