That Afib stands for atrial fibrillation (AF), which is a type of arrhythmia, or abnormal heartbeat. Afib is caused by extremely fast and irregular beats from the upper chambers of the heart (usually more than 400 beats per minute). A normal, healthy heartbeat involves a regular contraction of the heart muscle. A contraction happens about once per ...This review will focus on our current knowledge base of sex-related differences in atrial fibrillation (AF) and sustained ventricular arrhythmias/sudden cardiac death (SCD). Awareness of these differences may enhance arrhythmia detection and therapeutic decisions in women, thus improving their clinical outcomes.
