“HISTORICAL PERSPECTIVES OF THE TREATMENT OF CARDIAC ARRHYTHMIA” INTRODUCTION: The contraction and relaxation of the heart is represented in the form of electrical signals in electrocardiogram. Normally the depolarisation of SA node present in the right atrium of the heart is helpful in determining the heart rate of a person. SA node i.e. the sino atrial node is called the natural pacemaker of the heart. The electrical signal produced by the SA node starts the first beat, it causes the atria to contract and then these signals arrive AV node which allows ventricles to contract causing the blood to flow throughout the body. The normal rate at which heart beats is 60 to 100 beats per minute. Any changes in this rhythm cause cardiac…show more content…
Tilt Table Test: The heart rate and blood pressure is measured while lying on the table and then the table is tilted and doctor monitors the heart activity. Electrophysiological testing and mapping: Electrodes are placed in the heart and mapping of the electrical signals within the heart is done. (Scott C. Litin, October 6 2009) TREATMENT: For bradycardia generally an artificial pacemaker is used which implanted near your heart so when the heart slows down or stops pacemaker generates impulses in order to stimulate the heart. For tachycardia generally a pacemaker is used which emits impulses for the normal functioning of the heart. In this condition implantable cardioverter defibrillator is also used. It is recommended only when the patient is at high risk. When there occurs sudden cardiac arrest then this implantable device sends low or high impulses to reset the heart so as to beat in normal rhythm. Many surgical procedures like maze procedure in which doctors make an incision in the cardiac tissues and thus they does not conduct electricity and which results in lowering down of the heart rate, another surgical procedure involved is cardiac bypass surgery, this is performed when there are many other coronary artery problems other than arrhythmia. Minor tachycardia can also be controlled by medication. (Scott C. Litin,
