Everything You Need to Know Regarding Bundled Blood and Lab Testing

Bundled blood and lab testing are essential along with complete evaluation when you have a left bundle branch block. In case you’re healthy, a full examination is not mandatory.

About the Lab Testing

Some tests are performed to diagnose a bundle branch block. These are,

ECG or Electrocardiogram or EKG- An ECG is used to record the electrical impulses in the heart using wires attached to the skin on the chest or the limbs. This test shows indications of a bundle branch block and marks the affected side.

Echocardiogram- It utilizes sound waves to deliver the thickness of your heart muscle and explicit images of the heart structure. It exhibits whether or not the heart valves are functioning normally. Doctors can perform it to specify an ailment that is responsible for the bundle branch block.

Issues with Bundled Blood

Electrical impulses which are responsible for heart contraction begin in the heart’s upper right chamber or right atrium. Next, it travels to the lower chambers known as ventricles. In the case of a bundle branch block, the course these impulses follow is blocked or delayed.

A bundle branch block could be a partial or complete recess of the electrical pathway inside the heart wall. A block in the right bundle branch may happen to otherwise normal people. When it happens coupled with a heart attack, it could be a sign of severe damage to the heart muscle.


Usually, people with bundle branch blocks do not need any treatment as they have no symptoms. For example, doctors do not treat the block in the left bundle branch with medications. Treatment varies depending on the severity of cases and other heart conditions.


When you have ailments causing a bundle branch block, physicians refer to treatment that involves medications to reduce symptoms of heart failure or treat hypertension.

Surgeries and other Tests

When someone has a history of fainting or a bundle branch block, the physician may recommend a pacemaker. They implant a compact device called a ‘pacemaker’ under the skin of the upper chest. Two wires are there to connect the right side of your heart. The pacemaker expels electrical impulses to keep the regular heart beating.

Low heart pumping is another symptom of a bundle branch block. For low heart-pumping function, you may require cardiac resynchronization therapy. The treatment is quite akin to having a pacemaker implanted. But the patients may have a third wire connected to the left side of the heart. It enables the device to keep either side in proper rhythm. Cardiac resynchronization therapy improves the coordination of both the lower chambers of the heart enabling them to contract at the same time.


Left bundle branch block is rare in healthy and young people. This condition doesn’t have any effect on someone’s longevity provided he has no other underlying heart problems. Treatment is not necessary when the person has no other disease affecting the heart.
