What is the normal range for the RR interval in milliseconds?
The RR interval is the time between the beginning of two consecutive QRS complexes on an electrocardiogram (ECG). It is a measure of the heart rate, and a normal RR interval is between 600 and 1000 milliseconds.
The RR interval can be affected by a number of factors, including age, sex, and activity level. It can also be affected by certain medications, such as beta-blockers and calcium channel blockers.
The RR interval is an important measure of heart health. It can help to identify heart rhythm disorders, such as bradycardia and tachycardia. It can also be used to assess the effectiveness of certain medications.
If you are concerned about your RR interval, talk to your doctor.
RR Interval Normal Range in ms
The RR interval is a measure of the time between two consecutive heartbeats. A normal RR interval is between 600 and 1000 milliseconds (ms). The RR interval can be affected by a number of factors, including age, sex, and activity level.
- Chronotropic incompetence: Inability of the heart to increase its rate in response to exercise.
- Bradycardia: A heart rate that is slower than 60 beats per minute (bpm).
- Tachycardia: A heart rate that is faster than 100 bpm.
- Atrioventricular block: A condition in which the electrical impulses from the atria (the upper chambers of the heart) are delayed or blocked before reaching the ventricles (the lower chambers of the heart).
- Sick sinus syndrome: A condition in which the heart's natural pacemaker (the sinoatrial node) does not function properly.
- Vasovagal syncope: A condition in which the heart rate and blood pressure drop suddenly, causing fainting.
- Hypertrophic cardiomyopathy: This is a condition where the heart muscle is abnormally enlarged. It can lead to a number of symptoms, including chest pain, shortness of breath, and fainting.

Obesity
Obesity is a major risk factor for cardiovascular disease, including heart rhythm disorders. The RR interval is a measure of the time between two consecutive heartbeats, and a normal RR interval is between 600 and 1000 milliseconds (ms). Obesity can lead to an abnormal RR interval, which can increase the risk of heart rhythm disorders.
- Increased heart rate: Obesity can lead to an increase in heart rate, which can shorten the RR interval.
This is because obesity can cause the heart to work harder to pump blood throughout the body. As the heart rate increases, the RR interval decreases.
- Changes in heart structure: Obesity can also lead to changes in the structure of the heart, which can affect the electrical conduction system of the heart.
These changes can lead to an abnormal RR interval and an increased risk of heart rhythm disorders.
- Inflammation: Obesity is associated with inflammation, which can damage the heart and its electrical conduction system.
This inflammation can lead to an abnormal RR interval and an increased risk of heart rhythm disorders.
- Other risk factors: Obesity is often associated with other risk factors for cardiovascular disease, such as high blood pressure, diabetes, and high cholesterol.
These risk factors can also increase the risk of developing an abnormal RR interval and heart rhythm disorders.
If you are obese, it is important to talk to your doctor about your risk of developing an abnormal RR interval and heart rhythm disorders. There are a number of things you can do to reduce your risk, including losing weight, eating a healthy diet, and exercising regularly.
