  • Abstract
  • Look Inside

Electrophysiological studies were performed in 26 patients with sick sinus syndrome (SSS) and 12 controls before and after pharmacologic autonomic blockade (PAB) with propranolol (0.15 mg/kg) and atropine (0.04 mg/kg). Sinus cycle length (SCL) shortened sig-nificantly after PAB in both groups. PA and HV inter-vals did not change after PAB. AH interval shortened and Wenckebach period increased after PAB in SSS group. Maximum corrected sinus node recovery time shortened in the control group but did not change in the SSS group after PAB. Calculated sinoatrial conduction time shortened after PAB in both groups.
