Temporary coronary guidewire pacing during percutaneous coronary intervention.

Temporary pacing is occasionally required during percutaneous coronary artery interventions. This can be accomplished by the insertion of a temporary transvenous pacemaker wire into the right ventricle, but there is some risk and inconvenience associated with this approach. Temporary pacing using the coronary artery guidewire was described in 1985 but is used infrequently.

Assessment of anticoagulation using activated clotting times in patients receiving intravenous enoxaparin during percutaneous coronary intervention.

Enoxaparin is being used more frequently in patients undergoing percutaneous coronary intervention (PCI). In this study, we determined the effect of intravenous enoxaparin on activated clotting time (ACT) measurements in the setting of PCI. In 67 consecutive patients, either 1 mg/kg intravenous enoxaparin alone was given for anticoagulation or 0.
