Dobutamine infusion causes dose-dependent increase in heart rate and contractility. However, in some cases, it induces paradoxical sinus deceleration, whose underlying mechanism and clinical significance are not fully understood.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>We present episodes of paradoxical sinus deceleration observed during dobutamine stress echocardiography in six (four males and two females) patients and described its patterns of occurrence and clinical and echocardiographic characteristics.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Paradoxical sinus deceleration occurred mostly at maximal dobutamine infusion was accompanied with a decline in blood pressure and resolved spontaneously following cessation of dobutamine infusion.
