Abstract:
:In phaeochromocytoma, sudden hypertensive or arrhythmic episodes are believed to be associated with excessive free catecholamine excretion. However, lack of correlation between blood pressure (BP) and plasma catecholamine levels has been reported. Therefore an attempt was made to assess the sympathovagal balance before and during episodes of BP elevation or complex cardiac arrhythmias in this disease. Ten patients with phaeochromocytoma and 10 matched controls with essential hypertension underwent simultaneous 24 h Holter ECG and BP monitoring. BP elevation was diagnosed when the BP exceeded the mean 24 h values by 40 mm Hg systolic or 30 mm Hg diastolic, respectively. Heart rate variability (HRV) was measured for 5 min periods 1 h before, 15 min before and during 13 episodes of BP elevation in phaeochromocytoma and 13 episodes in the control group, as well as at 1 h, 15 min and immediately before five arrhythmic events in phaeochromocytoma. In phaeochromocytoma, vagal activity measured 1 h before BP elevation was markedly higher than in control hypertensives. However, in both groups at 15 min before and during the hypertensive events, the vagal tone decreased significantly. In contrast, just before the arrhythmic events HRV remained unaltered with a slight insignificant increase in sympathetic activity. We conclude that in phaeochromocytoma, pronounced BP elevations during daily activities are preceded by a parasympathetic withdrawal, similar to the findings in essential hypertension. Such a sequence does not seem to precede sudden complex arrhythmic events in phaeochromocytoma.
