Your heart is the main supplier of electrical power to your body. To put it simply, your heart functions as electrical machine. In all human beings, a normal heart beat is initiated by a small pulse of electric current which originates from pacemaker cells located at the top of your heart. Pacemaker cells are specialized in producing electricity. Thus, the first electric wave produced in your body starts at the top of your heart and spreads downwards all over the heart. Also called the S-A node, the pacemaker establishes the normal frequency at which your heart beats, or your heart’s biorhythm. Overall, your natural pacemaker and specialized electrical conduction cells and tissues, including your heart rate are controlled by signals from your brain through your involuntary nervous system to your pacemaker cells. Your involuntary nervous system also controls many other functions of your body including breathing, blood pressure, and excretion. You can see now that your heart produces electricity in addition to its well-known function of pumping and distributing blood to all parts of your body. The heart’s electricity naturally has its own electromagnetic field and vibration frequency.
Recent advances in scientific research have led to the development of man-made pace makers to assist a failing heart. The technological pacemaker is surgically inserted in the chest by medical doctors to deliver steady and regular electric impulses to a defective heart. The device can help stabilize the electric conduction system when the natural pacemaker cells are not functioning properly. When there is power failure in your heart due to disease or malfunction, everything else in the body ceases to function, signal from the brain ceases, blood flow to organ tissues stops, every other system in your body shuts down, you loose consciousness and life ceases. You are dead! No amount of oxygen will restore your life unless your heart’s electricity is restored. That’s why the doctor checks the heart first before he or she pronounces a person dead.
The ability of the heart to function effectively is affected by chronic stress and several disorders The major disorder that affects the electrical property of the heart is called cardiac arrhythmia which may cause heart failure. Signs and symptoms of arrhythmias include palpitations, chest discomfort, and shortness of breath, dizziness, and fainting. It was calibrated by God to beat at a certain rate. Abnormalities in the electrical functions of your heart and its electrical potentials can be detected by electrocardiogram (EKG), a procedure that records electrical changes in the heart. In medical practice, clinicians utilize the EKG for detection and diagnosis of cardiac arrhythmias, heart attacks, electrical conduction abnormalities, electrolyte disturbances, cardiac stress tests, and screening for various heart diseases.
