Central rate pressure product; new marker of cardiac load with exercise

Post-exercise changes in blood pressure, heart rate and rate pressure product at different exercise intensities in normotensive humans.

To evaluate the effect of exercise intensity on post-exercise cardiovascular responses, 12 young normotensive subjects performed in a randomized order three cycle ergometer exercise bouts of 45 min at 30, 50 and 80% of VO2peak, and 12 subjects rested for 45 min in a non-exercise control trial. Blood pressure (BP) and heart rate (HR) were measured for 20 min prior to exercise (baseline) and at i...

Effect of exercise on rate pressure product in premenopausal and postmenopausal women with coronary artery disease.

Incidence of coronary artery disease (CAD) increases sharply after menopause in women. Rate pressure product (RPP) is a major determinant of cardiac oxygen consumption. It is an important indicator of ventricular function. RPP varies with exercise. The peak rate pressure product (PRPP) which gives an accurate reflection of the myocardial oxygen demand and myocardial workload is the RPP at peak ...

Erosive Pressure Dermatitis Associated with Cardiac Pacemaker

Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...

Decreased exercise heart rate and blood pressure response in diabetic subjects with cardiac autonomic neuropathy.

Abnormal hemodynamic responses to exercise have been observed in diabetic subjects, but the pathogenesis and significance remain uncertain. We used maximal treadmill exercise to study 32 subjects with long-term insulin-dependent diabetes without clinical evidence of cardiac disease. Two of the 32 had occult ischemic heart disease revealed by stress electrocardiography and myocardial-perfusion s...
