29 year old. resting heart rate is over 200 at times?

If your resting heart rate is over 200 beats per minute (bpm) at times, it's important to seek immediate medical attention. This is considered to be a medical emergency and can be a sign of a serious underlying condition that needs to be evaluated and treated by a healthcare professional.

A resting heart rate of over 200 bpm is extremely high and can be caused by a variety of factors, including:

1. Cardiac Arrhythmias:

- Rapid heartbeats that occur due to abnormal electrical signals in the heart. Some common types of arrhythmias that can cause a high heart rate include supraventricular tachycardia (SVT), atrial fibrillation (AFib), and ventricular tachycardia (VT).

2. Thyroid Problems:

- An overactive thyroid gland (hyperthyroidism) can speed up the heart rate, leading to a resting heart rate over 200 bpm.

3. Anemia:

- A condition characterized by low levels of red blood cells, which can lead to a rapid heart rate as the heart works harder to pump oxygen-rich blood throughout the body.

4. Dehydration:

- Severe dehydration can cause the heart to beat faster in an attempt to maintain proper circulation.

5. Certain Medications:

- Some medications, including those used to treat asthma, thyroid issues, or weight loss, can cause an increase in heart rate.

6. Anxiety or Panic Attacks:

- Severe anxiety or panic attacks can trigger a sudden increase in heart rate.

7. Underlying Heart Conditions:

- Congenital heart defects, heart failure, or other heart-related conditions can cause a high resting heart rate.

8. Substance Abuse:

- Stimulant drugs, such as cocaine or methamphetamine, can cause a dangerously high heart rate.

It's crucial to seek medical attention as soon as possible if your resting heart rate consistently exceeds 200 bpm. Your doctor will perform a thorough evaluation, including diagnostic tests, to identify the underlying cause of your high heart rate and provide appropriate treatment.
