Abstract

Aim. To determine the influence of positive test of coronary reserve (TCR) and hypertensive reaction on the occcurrence of ventricular premature beats (VPBs) in ergometry test.
Methods. This study was carried out in the laboratory of ergometry in Karlovac General Hospital from December 2009 to May 2010. The research criteria was the use of beta blockers. Exclusive criteria were
cardiomyopathy, left ventricular hypertrophy, general aterosclerosis, hyperkaliaemia, hyperthyreosis and the use of digitalotherapy, bronchodilatators and other antiarrhythmic drugs. The age range of the patients was from 18 to 80 years of age.
Results. In the normotensive reaction there is no difference of incidence between negative and positive TCR in patients without and with VPBs (Z = -0.228; p = n.s.). In hypertensive reaction, the incidence of patients with positive TCR is bigger in VPBs patients than in patients without VPBs (Z = 2.043, p < 0.05).
Conclusion. Positive TCR in the ergometry test combined with hypertensive reaction increases the incidence of VPBs more than in the combination with normotensive reaction.
