What does it men to have a resting heart rate of 103?

A resting heart rate of 103 beats per minute (bpm) is considered high and can be a cause of concern. It is generally recommended to have a resting heart rate between 60 and 100 bpm, with lower rates typically being healthier. A heart rate consistently higher than 100 bpm when resting may be a sign of an underlying medical condition.

Possible causes of a resting heart rate of 103 bpm or higher include:

- Anxiety or stress

- Dehydration

- Fever or infection

- Certain medications (such as stimulants, decongestants, or thyroid hormone replacements)

- Hyperthyroidism (overactive thyroid gland)

- Anemia (low iron levels)

- Heart disease (including arrhythmias, valvular heart disease, or heart failure)

- Sepsis (severe infection)

It is important to consult with a healthcare professional if you have a resting heart rate of 103 bpm to determine the cause and receive appropriate treatment if necessary. The doctor may recommend further testing, such as an electrocardiogram (ECG) to evaluate your heart rate and rhythm, or other tests to identify any underlying medical conditions.

In some cases, a high resting heart rate may not be a cause for concern. For example, well-trained athletes may have a naturally lower resting heart rate due to increased heart efficiency. However, it is still important to see a doctor to rule out any potential medical issues, especially if the high resting heart rate is accompanied by other symptoms or if it develops suddenly without any obvious cause.
