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.
