Mapping for Acute Transvenous Phrenic Nerve Stimulation Study
Mapping for Acute Transvenous Phrenic Nerve Stimulation Study
The Mapping for Transvenous Phrenic Nerve Stimulation Study (MAPS) is being conducted to
 evaluate the feasibility of transvascular stimulation of phrenic nerves via an
 electrophysiology (EP) catheter advanced into the great veins.
Purpose The Mapping for Transvenous Phrenic Nerve Stimulation Study (MAPS) is being conducted
 to evaluate the feasibility of transvascular stimulation of phrenic nerves via an EP catheter
 advanced into the great veins.

 Study Design This is a prospective, non-randomized, acute feasibility study.
Inclusion Criteria:

 Exclusion Criteria:

 -  Subject with a previously implanted transvenous lead, which is still present in the
 veins under study.

 -  Subject with evidence of phrenic nerve palsy.

 -  Subject with chronic obstructive pulmonary disease.

 -  Subject with a spinal cord stimulator.

 -  Subject needs to receive drugs that might interfere with patient perception.

 -  Subjects with medical conditions that would prevent study participation

 -  Subjects who are pregnant, nursing, or of child bearing potential and are not on a
 reliable form of birth control
