Can an RBBB cause dizziness and chest pain?

Question

Hello doctor,

My husband went to the hospital four days ago because he felt dizzy and experienced chest pain. They found no troponin and told us his EKG was fine. His blood pressure in the hospital was 105/70 mmHg. The next day, we saw a cardiologist, who found a partial right bundle branch block and ordered more tests. Today, we learned that his grandmother had IHSS, which we were not aware of during our cardiology appointment. Today, he went to the grocery store and experienced the same dizziness symptoms, though not as severe as before. My concern is whether this warrants a visit to the ER. His blood pressure, 15 minutes after today's episode of dizziness, was 123/70 mmHg.

Please advise.

Hello,

Welcome to icliniq.com.

Thanks for your detailed explanation.

I understand your concerns, but there is not much to worry about. It is common to experience fainting and dizziness, especially in patients with RBBB (right bundle branch block), which I often see. RBBB is caused by a slow heart rate, which is why he is experiencing dizziness frequently. There is no need to worry about going to the ER, as his blood pressure and heart rate are normal for now. You should monitor his heart rate every two to three hours. If his symptoms persist and his heart rate drops below 60 bpm, you should consider taking him to the ER and inform them of his current condition.

I hope he feels better soon.
