September is National Atrial Fibrillation Awareness Month. Atrial Fibrillation (AFib) is the most common heart arrhythmia affecting up to 5 million Americans. Although AFib is the most common heart arrhythmia, it can affect people very differently. Oklahoma Heart Institute cardiac electrophysiologists, Dr. David Sandler, Dr. Gregory Cogert and Dr. Craig Cameron show us how AFib can be detected, treated and share common misunderstanding of the condition.
