[Evolution of diastolic polycardiographic indicators in hypertrophic cardiomyopathy].
In a group 26 patients with hypertrophic cardiomyopathy the values of certain polycardiographic and haemodynamic indices and their changes in the prolongation of the time of isovolumetric relaxation (IVRT) was noted in 23 patients (88%), with increased value of the percent of the a wave participation of the apexcardiogram (%a) in 24 patients (92%). In the obstructive type the corrected time of left ventricular ejection was significantly prolonged (p < 0.01) in relation to the non-obstructive type. No difference was observed in the values of these parameters depending on the functional class. A weak but significant correlation was demonstrated between the %a and the end-diastolic left ventricular pressure (r = 0.579, p < 0.01). The IVRT value showed an increasing tendency in this prospective study, particularly in patients with progression of clinical symptoms.
