Atrial flutter bradycardia

Bundle branch blocks usually do not cause symptoms . They are not considered to be irregular heartbeats or arrhythmias. Rarely, right bundle branch block may make symptoms worse in some people with heart failure.

Atrial fibrillation and atrial flutter are both types of SVT that are more common in older patients or patients with preexisting heart conditions . Atrial fibrillation can be more serious because, for some patients, it can lead to blood clots and increase stroke risk.

In people with known or suspected heart disease, right bundle branch block is associated with a greater risk of death, especially after a heart attack . Some people with right bundle branch block may ultimately need a permanent pacemaker, but this is rare.

Atrial fibrillation (AF) and complete right bundle branch block (RBBB) are independently associated with increased hemoglobin levels in apparently healthy subjects . Intern Med.
