What is tachy cardia mean?

Tachycardia refers to a condition characterized by an abnormally fast heart rate, typically defined as exceeding 100 beats per minute in adults. It can occur due to various factors, including stress, anxiety, fever, or underlying medical conditions. While occasional tachycardia may be harmless, persistent or severe cases can lead to complications and require medical evaluation. Treatment depends on the underlying cause and may involve lifestyle changes, medications, or other interventions.
