Normalization of Hemodynamic Parameters in Children with Autonomic Nervous System Disturbances

The present investigation is dedicated to the effects of the Medical Resonance Therapy Music^® on basic hemodynamic parameter in children with transient arterial hypertension due to disturbances of the autonomic nervous system with different degrees of initial sympatheticotonia.

After the nuclear accident of Chernobyl many children developed a blood pressure too high for their age norm. Having already observed a decrease in too high blood pressure in women during pregnancy we studied the effects of the Medical Resonance Therapy Music^® (MRT-Music) on such children – with very positive results:
the treatment with the music preparations demonstrated a clear sympatholythic effect and lead the disturbed hemodynamic state back to its healthy age norm.

Patients and methods

Under investigation were sixty children with different degrees of initial sympatheticotonia in the children's hospital No. 3 in Minsk. Two groups were examined: one group of 32 children with an absolute sympatheticotonia, in which 75%-100% of the initial autonomic tonus were built by the sympathetic part of the autonomic nervous system (ANS), and a second group of 28 children with a relative sympatheticotonia, in which 50%-75% of the initial autonomic tonus were build by the sympathetic part of the ANS. The initial tonus of the ANS was determined according to the index of Wein.

The MRT-Music^® treatments were performed twice a day at fixed times for three weeks.
During the treatment the patients listened to music preparations of the Medical Resonance Therapy Music^® with headphones. The average time of a treatment was 20-30 minutes under conditions suited to a maximum of relaxation:
a good light and noise isolation was guaranteed and the children listened to the MRT-Music^® in a comfortable, half lying position.

Before and after the treatment the following basic hemodynamic parameters were measured:

breath frequency (bf)
heart frequency (hf)
systolic pressure (sp)
diastolic pressure (dp)
mean arterial pressure (map)
pulse pressure (pp)

These measurements were taken using sympathomanometer according to the Korotkov method under consideration of the recommendations of the World Health Organization (1986). Other parameters under consideration were the minute volume of blood circulation (mvbc), the index of vegetative equivalence according to Hildebrandt (ih) as well as the vegetative index according to Kerdo (kerdo). The treatments were given according to the recommendations of Wein for the investigation of the autonomic nervous system.

Results

The investigations showed the following differences in the initial state of the organisms of the children:

The children of the first group showed higher parameters in breath and heart frequency as well as in diastolic and mean arterial pressure than the children in the second group, but they showed lower values in the systolic pressure,

and pulse pressure and the minute volume of blood circulation.

Analogue equivalences became even more clear by the analysis of the age norm which was calculated individually for each child.

Differences in the values of the initial state correlate fundamentally differently after MRT-Music^® treatment .

Table 3 shows that breath frequency, systolic and diastolic arterial pressure in the children of the first group was lower than in the second group. Heart frequency and mean arterial pressure had balanced, the minute volume of blood circulation had lowered very significantly, the Hildebrandt index had normalized.

Analysation of the deviation from the age norm (see table 4) shows, that in both groups breath frequency, heart frequency, systolic, diastolic and mean arterial pressure assimilated and pulse pressure and minute volume of blood circulation stayed below the average age norm, but without falling below the healthy limits.

In comparing the effects of the MRT-Music^® treatments the greater changes in the group with absolute sympatheticotonia were evident, which may be explained by the normalization of

the initially to high values. Remarkable is that after the MRT-Music^® treatments the parameters of the vegetative balance and of the inter-systemic relations practically stay the same.

Conclusions

The treatments with the Medical Resonance Therapy Music^® have a clear sympatholythic effect and lead the disturbed hemodynamic state of the child back to its healthy age norm.

The greater effects of MRT-Music^® treatments were seen in children with an initial absolute sympatheticotonia.

The Medical Resonance Therapy Music^® can be recommended as a complementary treatment to the traditional therapy for high blood pressure due to disturbances of the autonomic nervous system.

While performing the study no harming side effects or strong indications against the MRT-Music^® were registered.
