Okay, let's speak about a bundle branch block. First of all, you can relax entirely because at your young age, this is an incidental finding and right bundle branch block occurs very commonly in persons with completely healthy hearts.
When the main pacer of your heart, the sinoatrial node, generates a signal, it gets picked up by the atrioventricular node and is distributed to the bundle of His, where it becomes divided into the left bundle branch and the right bundle branch. So that your ventricles contract at a similar rate, these signals must be equal. In persons with bundle branch block, there is delay in one of the signals which causes the left and right ventricle to contract at slightly different times. This is not something that you can feel and it doesn't produce palpitations events.
The only consequence is a slightly delayed signal and in a healthy heart, is of no consequence. As stated, right bundle branch block is a very common phenomenon in healthy persons.
The actual cause of the palpitations is due to wayward impulse activity by the vagus nerve, which merely causes the heart to respond and is roughly the equivalent of a muscle twitch elsewhere in the body. These events are entirely incapable of causing you any harm, damaging the heart or otherwise placing you at any risk. While stress and anxiety are typically the underlying cause, GI disturbances or inflammation can also produce the events because the vagus nerve innervates the GI tract as the pneumogastric nerve at that level.
You'll be fine. Your doctor may choose to run further tests to rule out specific causes the the bundle branch block, but again at your age, my opinion is that it's an entirely incidental finding of no consequence.
Best regards and Good Health
