Blood pressure and rate-pressure product in angina.

Constancy of pressure-rate product in pacing-induced angina pectoris.

The pressure-rate product during anginal pain produced by right atrial pacing was studied in 12 patients before, during, and after an angiotensin infusion sufficient to produce a significant rise in blood pressure. During the infusion the pain occurred at a significantly lower heart rate (P less than 0.001). However, the pressure-rate product was similar during anginal pain before and during th...

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...

Relation of heart rate and systolic blood pressure to the onset of pain in angina pectoris.

SUMMARY Arterial pressure was recorded directly and continuously in 15 patients with angina pectoris while pain was repeatedly induced by exercise of various types and severity. In every case, the precipitation of angina could be consistently related to the level reached by the product of heart rate and systolic blood pressure (corrected when necessary for changes in ejection time). This relati...

Blood pressure and heart rate variability.

Inevitably, reading is one of the requirements to be undergone. To improve the performance and quality, someone needs to have something new every day. It will suggest you to have more inspirations, then. However, the needs of inspirations will make you searching for some sources. Even from the other people experience, internet, and many books. Books and internet are the recommended media to hel...
