Permanent pervenous atrial pacing from the coronary vein. Long-term follow-up.

Permanent pervenous atrial synchronized ventricular pacing.

Permanent pervenous atrial synchronized ventricular pacing was successfully accomplished in three patients. Atrial sensing was obtained from an electrode positioned in the coronary vein. Atrial electrograms with P waves greater than 1.5 mv were present in all three cases. Ventricular stimulation was accomplished through a separate electrode placed in the right ventricular apex. The left cephali...

Diagnostic and therapeutic uses of atrial pacing.

There are occasions when atrial pacing can be usefully employed both diagnostically and therapeutically. Diagnostically, atrial pacing provides mechanisms for easily, safely, and reproducibly stressing the heart that can help in the evaluation of patients with a variety of cardiac disorders. It is particularly useful in the assessment of patients with coronary disease. Therapeutically, atrial p...

Pervenous pacing of the specialized conducting system in man. His bundle and A-V nodal stimulation.

His bundle electrograms were recorded and A-V junction pacing was achieved in 30 patients by a pervenous electrode catheter technic. His bundle pacing was achieved in 26, and A-V node pacing in five patients. Conduction time from atrium to the His bundle (A-H time) and His bundle to ventricular activation (H-V time) were measured. During His bundle pacing, the pacing impulse to ventricular acti...
