description Paul Zoll Overview
Paul Zoll was an American cardiologist whose research established important clinical uses for electrical stimulation of the heart. In 1952, he reported successful external cardiac pacing in patients with heart block and cardiac standstill, using electrodes placed on the chest. He subsequently contributed to external defibrillation and long-term cardiac monitoring, helping make electrical therapy a practical part of treating dangerous disturbances of heart rhythm.

help Paul Zoll FAQ
How did Paul Zoll's first external pacemaker work?
Zoll delivered repeated electrical impulses through electrodes placed on the patient's chest. In 1952, he reported using this external stimulation to maintain heartbeats in patients with severe heart block.
Was Zoll's 1952 pacemaker implanted inside the body?
No. It stimulated the heart through the chest wall, which could be painful and required bulky external equipment; fully implantable pacemakers followed later.
What condition was Paul Zoll trying to treat with pacing?
His early work focused on cardiac arrest and complete heart block, in which electrical signals fail to drive an adequate heartbeat. External pacing could keep blood circulating when the heart's natural rhythm became dangerously slow or stopped.
Is the Zoll medical-equipment company connected to Paul Zoll?
Yes. ZOLL Medical Corporation took its name from Paul Zoll and developed products involving pacing, defibrillation, and resuscitation.
