Pathophysiological aspects of carotid sinus massage.

ABSTRACT:

Aims

We studied the blood pressure (BP) decrease after carotid sinus massage to study cardioinhibition (CI) and arterial vasodepression (aVD), whether CI and aVD occur independent of one another, and how the BP decrease ends.

Methods and results

We measured BP, heart rate (HR), stroke volume, and total peripheral resistance (TPR) retrospectively in carotid sinus massage cohorts in two Dutch syncope centres. Cardioinhibition and aVD were defined as HR and TPR decreasing below 3 SD under pre-massage baseline means. We used the logratio method to analyse changes relative to baseline and tested whether CI and aVD occurred together more often than through chance and whether the responses depended on massage duration and on corrective BP increases. Cardioinhibition occurred in 48%
