Abstract
Malignant cardiac arrhythmias are reported during prolonged drastic weight reduction with very low calorie diets (VLCD). Moreover, we could monitor potentially cardiac arrhythmias in a previously healthy obese adolescent girl treated with a alxed low calorie diet (2400 KJ) for only two weeks.
Therefore we studied cardiac function in 36 grossly obese adolescents (aged 12.1±0.6 years, overweight 54±4% mean±SE) who were treated with a 2000 KJ diet for weight reduction by 24 hour Holter monitoring before and during the treatment at one week interals (Del Mar Avionics, Model 500, USA). Weight loss during the low calorie treataent was 5.7±0.3 kg.
Analysis of variance showed a significant decrease of average heart rate (HRavg), minimal heart rate (HRmin) and maximal heart rate (HRmax) during the weight reduction. However, the number of patients who revealed ventricular (VES) and supraventricular (SVES) extrasystoles did not change significantly.
Neither before nor during the period of weight loss dysarrhythmias were seen.
