What are the symptoms of right bundle branch block?

The symptoms of right bundle branch block are not always apparent, and some people may not know they have the condition. A small percentage of people notice warning signs such as fainting, a persistent slow heartbeat, or actual fainting. It is not clear in all cases that this condition even requires treatment if the person has no symptoms. On the other hand, it is important to diagnose this condition because in some cases it can cause dangerous complications, such as heart failure, sudden arrhythmias, sudden death, or a very low heart rate.

Right bundle branch block is a disruption of electrical signals on the right side of the heart, which can interfere with the heart's regular beating. There are several causes for this condition. Some people are born with congenital heart disease that inhibits this electrical pathway. Alternatively, heart failure, heart attacks, certain heart surgeries, or a stroke can induce this electrical misconnection. Some people with high blood pressure or a recent pulmonary embolism are also likely to develop this disease.

As mentioned, many patients do not have symptoms of right bundle branch block. This is usually especially the case if the disease occurs congenitally. If symptoms occur sporadically, those who experience them are more likely to dismiss them. For example, feelings of faintness that occur from time to time can be attributed to low blood sugar or simply getting up too quickly. Most people also don't regularly monitor their heart rate and are unlikely to notice if it's beating slowly.

When symptoms of this faulty electrical pathway are noticed, it may be because they have become more pronounced. People may have fainting spells or frequent fainting spells. Doctors advise patients to seek treatment if they have passed out or are experiencing periods of dizziness, lightheadedness, or lightheadedness.

Another method by which right bundle branch block symptoms may be noted is during routine physical exams or follow-up care given after other heart problems have been identified. A very slow heart rate may be the only evidence of this condition, and may warrant a referral to a cardiologist or electrophysiologist. These specialists can perform further tests to evaluate the heart's electrical system and determine the cause of the problem.

Although many people never become symptomatic with this disease, some patients progress to a higher level of right bundle branch block symptoms and are at risk of serious complications. These include heart attack or complete failure of heart function, resulting in death. To prevent this outcome, doctors may recommend medication or implantation of a pacemaker. In contrast, asymptomatic patients often do not require treatment.
