Potentially harmful dc levels can be detected using the various test
configurations described below:

Static Tests (Pacemaker Power OFF):

These tests continuously measure dc leakage as follows:
• Atrial Channel: dc leakage across the atrial channel 500 Ω test load.
• Ventricular Channel: dc leakage across the ventricular channel 500 Ω
test load.
• AV Channel: dc leakage across an auxiliary 500 Ω test load
connected to the +atrial and +ventricular outputs.
