What is it indicated for?

The models 436-07 and 437-07 pacing leads are intended for use with implantable cardiac pulse generators for long-term pacing of the heart. The indications for ventricular pacing include, but are not limited to: Sick sinus syndrome, sinus bradycardia, complete heart block, symptomatic second-degree heart block, and certain conditions of asymptomatic second-degree block. In the presence of normal A-V conduction the indications for atrial pacing include…

Read the full statement (120 words)

The models 436-07 and 437-07 pacing leads are intended for use with implantable cardiac pulse generators for long-term pacing of the heart. The indications for ventricular pacing include, but are not limited to: Sick sinus syndrome, sinus bradycardia, complete heart block, symptomatic second-degree heart block, and certain conditions of asymptomatic second-degree block.

In the presence of normal A-V conduction the indications for atrial pacing include, but are not limited to: Sinus arrest, sick sinus syndrome, sinus bradycardia and conditions requiring increased cardiac efficiency, enhanced cardiac output or the overdrive of certain cardiac arrhythmias.

In the absence of normal A-V conduction, an atrial lead may be used with a ventricular lead in a dual chamber pacing system to restore A-V synchrony.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
