Is tachycardia dangerous

Tachycardia, characterized by a rapid heartbeat, can be dangerous depending on its cause and duration. While temporary increases in heart rate due to stress or exercise are usually harmless, persistent or severe tachycardia may indicate underlying health issues, such as Heart disease or arrhythmias, and can lead to complications like heart failure or stroke. It's essential to consult a healthcare professional for a proper evaluation if tachycardia occurs frequently or is accompanied by symptoms like chest pain or dizziness.
