The Prolonged PR Interval: What You Need To Know

Did you know that a prolonged PR interval can signal a heart problem? In this article, we will discuss the prolonged PR interval, what causes it, and some potential risks associated with it.

The prolonged PR interval is an electrical signal recorded on an electrocardiogram (ECG). It is the amount of time it takes for the electrical impulse to travel from the atria to the ventricles of your heart. A prolonged PR interval usually means problems with how electricity is conducted through your heart, resulting in a prolonged time until the ventricles are activated.

The most common cause is an abnormality of the electrical pathways between the atria and the ventricles, known as first degree AV block. Other causes could be prolonged QRS intervals (the time it takes for the heart to contract and pump blood), electrolyte imbalances, and drug toxicity.

Common symptoms include chest pain, dizziness, fainting spells or palpitations. Other more serious complications associated with prolonged PR interval include heart attack, stroke or cardiac death.

A prolonged PR interval can be a sign of underlying heart-related issues and should not be taken lightly. You must speak to your doctor if you have any prolonged PR interval symptoms so they can take the necessary tests to diagnose or rule out any serious conditions.
