indications chronic avhb chronic bifascicular and trifascicular block avhb after acute mi sinus node dysfunction hypersensitive carotid sinus and neurally mediated syndromes miscellaneous pacing indications chronic avhb especially if symptomatic pacemaker most commonly indicated for type ۲ ۲º block occurs within or below the bundle of his ۳º heart block no communication between atria and ventricles chronic bifascicular and trifascicular block differentiation between uni bi and trifascicular block syncope common in patients with bifascicular block intermittent ۳º heart block common block in the conduction systems below the bundle of his in the bundle branches right bundle branch and anterior and posterior fascicles of left bundle branch avhb after acute mi incidence of high grade avhb higher indications for pacemaker related to intraventricular conduction defects rather than symptoms prognosis related to extent of heart damage sinus node dysfunction sinus bradycardia sinus pause or arrest or sinoatrial block chronotropic incompetence often associated with paroxysmal svts bradycardia tachycardia syndrome may result from drug therapy symptomatic often the primary indication for a pacemaker chronotropic incompetence is known as a deficient rate response or stress or exercise symptomology determined with ambulatory monitoring pacemaker does not necessarily improve survival. dual chamber pacing improves survival greater than ventricular pacing alone. hypersensitive carotid sinus syndrome syncope or presyncope due to an exaggerated response to carotid sinus stimulation defined as asystole greater than ۳ sec due to sinus arrest or avhb an abrupt reduction of bp or both decreased blood pressure due to vasodilation pure cardioinhibitory response pacing helps most people have a mixed response and attention must be given to both components. neurally mediated syncope ۱ ۴ of patients with syncope triggering of a neural reflex use of pacemakers is controversial since often bradycardia occurs after hypotension in a recent study a ۸۵ reduction in risk of recurrent syncope in patients randomized to dual chamber pacing miscellaneous hypertrophic obstructive cardiomyopathy dilated cardiomyopathy cardiac transplantation termination and prevention of tachydysrhythmias pacing in children and adolescents dual chamber pacemaker with a short atrioventricular delay reduces the magnitude of left ventricular outflow tract obstruction pacemakers may help by changing the contraction pattern of the ventricle alleviates symptoms improve

alternative to emergency transvenous pacing mechanics  provide the rhythm heart cannot produce  either temporary or permanent  consists of external or internal power source and a lead to carry the

electrode that contacts the heart at its tip pole the power source is the pole patient serves as the grounding source patient’s body fluids provide the return pathway for the electrical signal electromagnetic interference occurs more often in unipolar leads unipolar pacemaker bipolar pacemaker if bipolar there are two wires to the heart or one wire with two electrodes at its tip provides a built in ground lead circuit is completed within the heart provides more contact with the endocardium needs lower current to pace less chance for cautery interference bipolar pacemaker indications ۱.
