What is the difference between tachycardia and bradycardia?

Tachycardia and bradycardia are terms that describe the heart's rate and heart rhythm.

- Tachycardia: Is a condition where the heart rate exceeds the normal range. This can be caused by various things such as anxiety, stress, exercise, or underlying health conditions such as thyroid issues or an infection. Tachycardia is usually characterized by a heart rate of more than 100 beats per minute.

- Bradycardia: Is a condition where the heart rate is slower than the normal range. This can also be caused by various factors, such as the body being in a resting state, such as during sleep, or underlying medical conditions such as thyroid problems or heart disease. Bradycardia is characterized by a heart rate below 60 beats per minute.

Both tachycardia and bradycardia can be signs of an underlying medical condition, so it is important to see a doctor if you experience either of these conditions to determine the cause and receive the proper treatment.
