The heart frequency and it\u27s variability in hypertensive patients considering A/B type of behaviour and eight basic emotions and levels of anger expression

Abstract

U ovom radu istraživali smo autonomnu regulaciju rada srca putem frekvencije srca i njene varijabilnosti kod 100 bolesnika s esencijalnom hipertenzijom i usporedili sa 100 ispitanika zdrave kontrolne grupe. Bolesnici s esencijalnom hipertenzijom imali su značajno kraći prosječni RR interval, odnosno bržu frekvenciju srca nego kontrolna grupa. Prosječna varijabilnost frekvencije srca je statistički značajno niža u hipertenzivnoj, nego u zdravoj kontrolnoj grupi. Na frekvenciju srca i njenu varijabilnost ukupno značajno utječu, pri mirnom i dubokom disanju: sistolički tlak, dijastolički tlak, masa lijevog ventrikula, dijastolička disfunkcija lijevog ventrikula, veličina lijevog atrija, trajanje hipertenzije, visina kolesterola i triglicerida. Najznačajnija negativna povezanost nađena je između varijabilnosti frekvencije srca i trajanja hipertenzije. U hipertenzivnih bolesnika i u kontrolnoj skupini češći je “A tip” nego “B tip” ponašanja. U hipertenzivnoj grupi statistički je značajan ukupan utjecaj svih nezavisnih varijabli po Bortneru na varijabilnost frekvencije srca pri mirnom disanju. Frekvencija srca i njena varijabilnost povezane su sa osam temeljnih emocija kodu hipertenzivnih ispitanika i kontrolne skupine. U grupi hipertenzivnih bolesnika varijabilnost frekvencije srca značajno je pozitivno povezana s emocionalnom dimenzijom “Inkorporacija”, a negativno s emocionalnim dimenzijama “Zaštita”, “Odbacivanje” i “Reprodukcija”. Naši podaci pokazuju da bolesnici s dugotrajnom hipertenzijom imaju povišenu frekvenciju srca i reduciranu varijabilnost frekvencije srca, što su poznati čimbenici rizika za povišeni kardijalni mortalitet.The aim of this paper was to comparation between autonomic regulation of the heart rate and it\u27s variability within 100 essential hypertensive patients and 100 examinees in healthy control group. Essential hypertensive patients had significantly shorter average RR interval, that is, faster heart frequency then the control group. Average variability of the heart frequency was statisticaly considerably lower in hypertensive than in the healthy control group. Sistolic blood pressure, diastolic blood pressure, duration of hypertension, levels have considerate total influence on heart frequency and it\u27s variability during calm and during deep breathing. The most distinctive negative connection was found between variability of the heart frequency and duration of hypertension. The type A behaviour within hypertensive patients and the control group was more common then type B. In the hypertensive group, total influence of all independent Bortner\u27s variables on to variability of the heart frequency during calm breathing was statisticaly important. Within hypertensive patients and the control group, the heart frequency and it\u27s variability were connected with eight basic emotions. In the group of hypertensive patients variability of the heart frequency is significantly positively connected with emotional dimension "Incorporation", but negatively with emotional dimensions "Protection", "Rejection" and "Reproduction". Our data showes that patients with long-term hypertension have increased heart frequency and reduced variability of the heart frequency, which are well-known risk factors for increased cardial mortality
