Can you detect artery blockage with an ECG?

March 17, 2021

With all of the modern advancements in medical science, there are plenty of procedures that can help unclog your blocked arteries. But before you can do that, you need to find where the issue is or determine if the issue that you have is a blocked artery. Sure, your doctor will perform some routine procedures on your first check up, but those might not reach the heart of the problem. This is when the doctor pulls out the Electrocardiogram (which is the long way to call an ECG; which is also known as an EKG). But can EKG show blocked arterie? 

Blocked Artery Warning Signs

First, let's look at the warning signs and routine procedures that come into play before the ECG is pulled out. If you are experiencing some of the following issues, you should get yourself to a doctor:
• Chest Pains
• Breathlessness
• Heart Palpitations
• Sweating

I know these are not obvious signs, but if you are finding yourself experiencing these symptoms consistently, you should get yourself to a doctor so they can check your heart for any number of heart issues. Once you are in the office, the doctor will perform several routine procedures to check if you have:
• Rising Blood Pressure
• Any Sounds Associated with Heart Failure in your Heart of Lungs
• Swollen Neck Veins
• Enlarged Liver
• Swollen Feet

Can you detect blocked arteries from an ECG?

If the doctor has found any issues in these routine procedures, they will then bring out the ECG. This will help the doctor read the electrical signals given off by your heart so they can read what could possibly be wrong with it. It is a non-invasive way to review your heart activity, as all they have to do is place a couple of pads on your chest and they can detect any abnormal behaviors within your heart. Once the ECG is placed on your heart, it will need to sit there for a few minutes so it can get an accurate reading of your heart by the electrocardiograph. This information is all displayed as a trace on a screen or a piece of paper.

But Will a Blocked Artery Show Up on an ECG?

An ECG result from a healthy heart has a specific characteristic that is not unique; everyone should have this same shape. If there is an issue or abnormality within your heart, the doctor will be able to pick up on it from one glance at your Electrocardiograph.

These issues could be one of the following:
• Previous Heart Attacks
• Blocked Arteries
• Abnormal Rhythms
• Congenital Heart Defects
• Heart Enlargement

From there, the doctor will need to dig deeper to determine what the exact issue is. But yes, you can find a blocked coronary artery with an ECG

While an ECG will help determine if you have blocked arteries, your doctor will still need to do more in order to determine the right course of action to take. With all of the options that are available to the modern doctor, taking the time to reexamine the data will be the difference between your life and death. As long as you are able to get your ECG information to a doctor as soon as possible, you will be one step closer to a healthy heart.
