    Hello, I'm an expert in cardiology with a focus on electrophysiology. I'd be happy to help answer your question. A right bundle branch block (RBBB) is a pattern seen on an electrocardiogram (ECG) that indicates a delay or blockage in the electrical conduction system of the right side of the heart. It's important to understand that an RBBB itself is not a direct cause of a heart attack, which is medically known as a myocardial infarction (MI). However, an RBBB can be a sign of underlying heart disease, which could potentially increase the risk of a heart attack. For instance, if the RBBB is due to a previous heart attack or ischemia (reduced blood flow to the heart muscle), it could be related to the heart's condition that might make a person more susceptible to another heart attack. Additionally, certain conditions that can cause RBBB, such as hypertrophic cardiomyopathy or coronary artery disease, are also risk factors for heart attacks. It's also worth noting that an RBBB can sometimes be seen in individuals without any heart disease at all, especially in older adults or athletes, and in these cases, it's considered a normal variant and is not associated with an increased risk of heart attack. In summary, while an RBBB is not a direct cause of a heart attack, it can be a marker for heart conditions that might increase the risk. It's always important to discuss any ECG findings with a healthcare provider to understand the context and any potential risks. read more >>

    Bundle branch blocks usually do not cause symptoms. They are not considered to be irregular heartbeats or arrhythmias. A block in the right bundle branch can occur in people who otherwise seem normal. If it happens with a heart attack, it can be a sign of serious heart muscle damage.read more >>
