Cardiac electrophysiology stimulation system

This category covers systems designed to deliver controlled electrical impulses to the heart for diagnostic purposes during cardiac electrophysiology studies. These assemblies include external pulse generators and electrode leads that stimulate heart tissue to evaluate conduction pathways, induce or terminate arrhythmias, and assess the sinus node's functionality. They operate by emitting precisely timed pulses across a range of cycle lengths to simulate different cardiac rhythms and gather physiologic data.

Devices in this category are supplied as complete systems comprising an external pulse generator and associated leads, configured for clinical diagnostic use. They are utilized in specialized cardiac settings to perform tests on atrioventricular conduction and tachycardia management. The systems are designed to function in both asynchronous and synchronous modes, allowing for variable stimulus strengths to meet specific procedural requirements.
