![]() ![]() Transcutaneous pacing is temporary and uncomfortable, and its use requires hospitalization. In emergency situations, transcutaneous pacing can be performed using large ECG electrodes connected to a defibrillator. If the battery is depleted, the entire generator is replaced. Battery life varies but typically lasts 6 to 12 years. Permanent pacemakers have insulation to protect against moisture and filters to prevent electrical interference. Temporary pacemakers use leads connected to a temporary generator, while permanent pacemakers have leads connected to a subcutaneously implanted generator. The pacemaker leads can be endocardial (placed inside the heart) or epicardial (placed outside the heart during open-heart surgery). Sensitivity settings allow the device to detect intracardiac electrical activity. The pulse generator contains circuitry and batteries that determine the rate and strength of the electrical stimulus. Pacemakers consist of an electronic pulse generator and pacemaker electrodes, which deliver controlled electrical stimuli to the heart muscle. The pacemaker consists of a pulse generator and leads that are implanted in the heart, delivering electrical stimuli to maintain a stable heart rate. Pacemakers can be permanent or temporary, with temporary ones being used in hospital settings until a permanent pacemaker can be implanted. ![]() Biventricular pacing, known as cardiac resynchronization therapy (CRT), is used for advanced heart failure. They are used in patients with slower-than-normal impulse formation, conduction disturbances, or certain tachydysrhythmias. Pacemakers are electronic devices that deliver controlled electrical stimuli to the heart muscle to regulate its rhythm. Initiating Health Teaching and Patient Education Managing Body Image Disturbance and Self-Esteem Improving Cardiac Tissue Perfusion and Cardiovascular Monitoring Gain valuable insights on nursing assessment, interventions, goals, and nursing diagnosis specifically tailored for pacemaker therapy in this guide. However, not seeing pacer spikes can be normal, such as when the patient's heart is beating faster than the rate set on the pacemaker.Utilize this comprehensive nursing care plan and management guide to provide effective care for patients undergoing pacemaker therapy. You'll need a chest X-ray to rule out a fractured lead wire. If oversensing is the likely cause of the failure to pace, lower the mV on the sensitivity dial, as it raises the sensitivity of the pacemaker, and remove items that could cause electromechanical interference such as electric razors, radios, or cautery devices. A pacemaker will sense, or pick up and interpret, muscle movement and artifact as heart beats if the sensitivity threshold is set too high, or there are items in the vicinity of the pacemaker that interfere with its signals, or the lead wire is fractured. If you're still not seeing pacer spikes it may mean the pacemaker is oversensing. (A good rule of thumb is to replace them every two to three days.) Then, check to make sure all connections are tight. Always check the batteries and replace them if necessary. Failure to pace is confirmed when there's no pacer spikes shown on your EKG or telemetry strip. Multiple causes including oversensing, wire fracture, lead displacement, or interference.Results in decreased or absent pacemaker function. ![]()
