Sinus Tachycardia: What You Need to Know
Published: Jan 17, 2024
Sinus tachycardia is more than just a fast heartbeat. Understanding this condition can help you manage its symptoms and potential risks.
What is Sinus Tachycardia?
Sinus tachycardia occurs when the heart beats faster than usual due to signals from the sinoatrial node. It can be a normal response to exercise or stress but might indicate underlying health issues if persistent. A heart rate over 100 beats per minute characterizes this condition.
Common Causes and Symptoms
Sinus tachycardia can result from various factors like fever, dehydration, stress, or medical conditions like hyperthyroidism. Symptoms may include palpitations, shortness of breath, and dizziness. Understanding these causes helps in managing the condition effectively.
Diagnosis and Evaluation
Diagnosis typically involves an ECG to confirm the heart's rhythm. Additional tests may explore underlying causes like infections or hormonal imbalances. A healthcare provider will guide the evaluation process to rule out other potential heart issues.
