Symptoms
The most obvious sign of sinus tachycardia is an increased heart rate, typically above 100 bpm. In addition, there are some other typical symptoms, including irregular heartbeats, changes in blood pressure, anxiety, chest pain, fainting, dizziness, breathing issues, and strong heartbeats. You can feel these effects at any time during the day, especially after a physical activity. It is important to consult your doctor as soon as you notice these signs. If left untreated for an extended period, sinus tachycardia would lead to more serious complications for your heart and other body parts. [3]
