How is bundle branch block diagnosed?

Healthcare providers diagnose BBB with two main tests:

• Electrocardiogram (EKG): During an EKG, your provider attaches electrodes to the skin of your chest. You lie still while a computer records a tracing of electrical impulses that travel through your heart. An EKG can also show which side of your heart has the bundle branch block.
• Echocardiogram: During an echocardiogram (echo), your provider places a hand-held wand on your chest. High-frequency sound waves create pictures of your heart’s chambers and valves. Your provider can see the motion and rhythm of your heart as it beats. They can also check for heart disease and other underlying conditions.

If your provider diagnoses you with BBB, they will check you for related health conditions. They may recommend the following tests:

• Blood pressure reading, to look for high blood pressure (hypertension) or low blood pressure (hypotension).
• Blood test, to check cholesterol levels.
• Cardiac catheterization, to look at the blood vessels in your heart.
• Nuclear cardiac stress test, to look for coronary artery (heart) disease.
• Pulmonary function testing, to see how well your lungs are working.
