Artificial pacing of the heart has evolved rapidly over the last 20 years; the physician can now implant "physiologic" pacemakers that preserve the natural order of atrial and ventricular systole. The commonly used pacemakers that pace only the ventricle can induce dizziness, fatigue and syncope and increase congestive heart failure. Physiologic pacemakers can eliminate many of these side effects, but they are more expensive, can be less durable and may induce arrhythmias. Physiologic pacing can provide the greatest benefit and cost-effectiveness when the particular functions of the device are matched to the specific needs of the patient.
在过去20年里,心脏人工起搏技术发展迅速;如今医生能够植入可维持心房和心室收缩自然顺序的“生理性”起搏器。常用的仅对心室进行起搏的起搏器会引发头晕、疲劳和晕厥,并加重充血性心力衰竭。生理性起搏器可消除许多此类副作用,但价格更高,耐用性较差,且可能诱发心律失常。当设备的特定功能与患者的具体需求相匹配时,生理性起搏可带来最大益处和成本效益。
