The sinoatrial (SA) node is the
main pacemaker of the heart that is located in the right atrium, the right
upper chamber of the heart. This determines the normal rhythm and the heart
rate which is normally between 80-100 beats per minute. In the case of AF,
there are rapid electrical signals originating from the cells of the right
atrium that bypass the SA node. This would eventually produce a rapid and
irregular heart rate. University of
Miami Cardiology has noted classical signs of extremely high heart rate due
to AF which include loss of consciousness (syncope), lightheadedness or
dizziness, chest pain, shortness of breath, and palpitations.

Cases of AF should always receive
special medical attention from Miami
international cardiology consultants. With their thorough knowledge and
interventions on managing heart rhythms, AF can be relieved saving the patient
from any greater risk of developing complications. With persistent AF, doctors
can prescribe medications to control the condition and convert it to a normal
heart rhythm. Special procedures involved in the management of AF include
electric shock or ablation therapy. Cases of abnormal heart rhythm should
always be reported to physicians for proper management. You must be able to
avoid increasing the risk for any complication of a persistent abnormality in
your heart function.
