Transcutaneous cardiac pacing: expanding clinical applications.
Transcutaneous cardiac pacing is an exciting alternative to invasive endocardial pacing methods for the treatment of hemodynamically significant bradyarrhythmias. Prompt institution of a pacing support system is crucial for improving outcomes in this patient population. Recent advances in technology and microcircuitry have eliminated the problems of painful, musculoskeletal stimulation and excessive distortion of the ECG signal associated with earlier devices. The ease of application and simplicity of operation associated with this technique make it ideally suitable for employment in the emergent situation, especially in the prehospital setting. The noninvasive nature of this technique is particularly beneficial for patients receiving thrombolytic therapy who are at risk for developing reperfusion dysrhythmias. Prophylactic use of transcutaneous pacemakers in a variety of clinical situations, such as atrioventricular blocks, may eliminate the need for transvenous electrode insertion and its related complications. A transcutaneous pacing system with the capability of functioning in the demand mode should be readily available in emergency rooms, intensive care units, and telemetry floors. Although unlikely to replace transvenous methods, the growing popularity of this technique has many implications for the nurse in the critical care setting.
