| Abstract: | 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. |
