Elevated Heart Rate

Higher resting heart rate was shown to correlate with worse prognosis both in general population and in various disease groups. Scientific societies dealing with patients with hypertension propose assessment of resting heart rate as a standard risk factor. In patients with uncomplicated hypertension and elevated resting heart rate they propose use of cardioselective β1-adrenolytics. This decision should be preceded by careful examination of potential modified reasons. In the paper we express several concerns regarding standard provision of heart rate lowering drugs in particular clinical situations. The algorithm showing proposed steps in assessment of elevated heart rate is provided.

Elevated Heart Rate

The influence of hypercapnia on mesenteric blood flow was studied in dogs subjected to progressive increments in CO2 content of inspired air produced by rebreathing from a large spirometer. Oxygen content was maintained above 21 volumes %. Although some animals showed an initial tendency for mesenteric blood flow to decrease and arterial pressure to increase in the range 0–5 volumes % of CO2, the usual hemodynamic change in the range 5–16 volumes % was an increase in mesenteric blood flow resulting from decrease in intestinal vascular resistance, accompanied by a decline in arterial pressure. Portal venous pressure was progressively elevated. Heart rate slowed in association with an increase in pulse pressure. The observations suggest that in higher ranges of hypercapnia, CO2 has a direct dilating action on the mesenteric vasculature.
