Read the full statement (194 words)
The intended uses of Lifetech Cardio Temporary Pacemaker are
1. to provide temporary single chamber synchronous or asynchronous anti-brady pacing therapy, and
2. to test electrical performance of an implanted lead system, including pacing threshold, sensing sensitivity and
impedance .
Lifetech Cardio Temporary Pacemaker is only intended to be operated 1. in a clinical setting, and 2. by trained
professionals.
Indications for anti-brady pacing therapy may be based on symptomatic bradycardia conditions that:
1. results from an acute and reversible cause and will likely not require permanent pacing, and
2. causes symptoms and/or severe hemodynamic impairment and when permanent cardiac pacing is not immediately
indicated or available.
Examples of specific indications for temporary pacing may include:
a) Sick sinus syndrome
b) Sinus bradycardia
c) Atrial and/or ventricular arrhythmias
d) Complete atrioventricular block
e) Asystole
f) Bradycardia accompanied by congestive heart failure
g) Patient support, management and evaluation before the implantation of implantable pacemaker
h) Support during the replacement of implantable pacemaker
i) Cardiac complications occurring during intervention or surgery
j) Support after the cardiac surgery
k) Acute myocardial infarction complicated with cardiac conduction block
l) High-rate burst pacing for the treatment of supraventricular tachyarrhythmias
Indications for use as stated in the FDA summary.
