When does exercise-induced tachycardia become risky

The article explains that an increased heart rate during exercise is normal, but it becomes dangerous if accompanied by symptoms such as chest pain, shortness of breath, dizziness, or irregular palpitations. It is recommended to stop exercising and seek immediate medical help if these symptoms appear, especially if they are accompanied by chest pressure or fainting. The article also clarifies that the maximum heart rate can be quickly estimated by subtracting your age from 220, and moderate activity aims for 50-70% of this maximum. It is important to consult a doctor if you have heart disease or are taking medications. Caution should be exercised in case of sudden palpitations, and exercise should be stopped immediately. Medical evaluation is essential before resuming intense activity.
