What are arrhythmias Arrhythmias or dysrhythmias are abnormal rhythms of the heart. Arrhythmias cause the heart to pump less effectively. Normally the heartbeat starts in the right atrium when a special group of cells (the sinus node or“pacemaker” of the heart) sends an electrical signal. This signal spreads throughout the atria and to the atrioventricular (A-V) node. The A-V node connects to a group of fibers in the ventricles that conduct the electric signal. The impulse travels down these specialized fibers to all parts of the ventricles. This exact route must be followed to ensure the heart pumps properly. للتواصل معنا مهدي الأشقر هان - ألمانيا TEL: 0049 -152 0 982 9849 FAX: 0049 2129 348 9561 info@wecare-germany wecare-germany
