Does intravascular ECG monitoring using a guidewire improve signal quality and prevent dysrhythmias compared to a fluid column-based system during central venous catheter placement?
Intravascular ECG monitoring using a guidewire provides superior signal quality compared to a fluid column-based system and can prevent dysrhythmias during central venous catheter placement.
