Detailed explanation-1: -Tachycardia is an increased heart rate for any reason. It can be a usual rise in heart rate caused by exercise or a stress response (sinus tachycardia). Sinus tachycardia is considered a symptom, not a disease. Tachycardia can also be caused by an irregular heart rhythm (arrhythmia).
Detailed explanation-2: -Stress, exercise, or even too much alcohol or caffeine can cause your heart to beat faster than normal. But if your heart races a lot-or if you notice your heartbeat is often irregular-then you should see a doctor.
Detailed explanation-3: -Causes of supraventricular tachycardia (SVT) SVT happens when the electrical system that controls your heart rhythm is not working properly. This causes your heart to suddenly beat much faster. It can then slow down abruptly. A normal resting heart rate is 60 to 100 beats per minute (bpm).
Detailed explanation-4: -Tachycardia in adults refers to a heart rate of more than 100 beats per minute. How that’s defined may depend on your age and physical condition.
