In general, pacemaker implantation is indicated in patients with a documented irreversible bradycardia which causes symptoms. Symptoms associated with bradycardia can be lightheadedness, palpitations, dyspnea, angina and syncope. The causal relation between the abnormal heart rhythm and symptoms is crucial for the decision to implant a pacemaker. | In general, pacemaker implantation is indicated in patients with a documented irreversible bradycardia which causes symptoms.

Thereafter, the pacemaker pulse generator is implanted subcutaneously or subpectorally under the left or right clavicle. | If these tests are within limits, the pacemaker leads are properly positioned.
