Harm/ aetiology Prognosis Therapy

Bradycardia permanent pacemakers decreased syncope and heart failure. Level of evidence 1b Expiry Date August 2003 Bradycardia theophylline may decrease heart failure. Level of evidence 1b- Expiry Date August 2003 Bradycardia fewer patients developed pacemaker syndrome with dual-chamber pacemakers Level of evidence 1b Expiry Date August 2003 Bradycardia antibiotics decreased pacemaker infection. Level of evidence 1b Expiry Date August 2003 Bradycardia potassium, glucose and insulin increased survival. Level of evidence 2b Expiry Date August 2003 Bradycardia balloon-flotation catheters were easier to position optimally Level of evidence 1b Expiry Date August 2003 Bradycardia ventricular pacing increased thromboembolisms. Level of evidence 1b Expiry Date August 2003 Bradycardia transcutaneous pacing may increase survival to discharge. Level of evidence 2b- Expiry Date July 2003 Bradycardia antibiotics had no clear effect on infection by pacing catheters. Level of evidence 2b- Expiry Date August 2003 Cardiac arrest bretylium tosylate had no clear effect. Level of evidence 2b- Expiry Date October 2003 Cardiac arrest brady-asystolic: no clear role for external pacing Level of evidence 2b- Expiry Date November 2003 Myocardial infarction bradycardia: atropine improved vital signs Level of evidence 4 Expiry Date October 2003 Pacemakers antibiotic prophylaxis reduces infection rate. Level of evidence 1a Expiry Date July 2003 Sick sinus syndrome atrial pacing reduced death and thromboembolic events better than ventricular pacing. Level of evidence 1b Expiry Date October 2003
