Objectıve
In this study, electrocardiograms (ECG) of detainees and convicts proceeding on hunger strike are compared with those taken after the hunger strike.
Methods
Between September 2012-November 2012, 81 male (mean age 41±9.4 years) detainees and convicts on hunger strike approximately 45 ± 9.6 days long were conducted in this study. The mean duration of fasting was 45±9.6 days. Blood pressures, body weights and serum electrolytes (Na, K, Ca) obtained on the last day of the hunger strike and 2 months after it. 12-lead ECGs obtained on the last day of the starvation and 2 months after starvation were scanned, transferred to high-resolution computer screens and evaluated.
Results
On an average 6 ± 3.7 kg loss was observed in 81 patients on hunger strike. When the ECGs taken on the last day of the starvation were evaluated, 16 (19.7%) early repolarization (ER) (inferior: 10, lateral: 5, inferolateral: 1) were detected and in those taken two months after the strike 4 (4.9%) early repolarization (inferior: 3, lateral: 1) (p<0.001) were detected. Significant difference was found in PR interval (157±75 ms vs. 153±23 ms, p: 0.035) and QRS duration (95±73 vs. 92±11, p: 0.001) whereas there was no difference in terms of heart rate (p: 0.068). Additionaly, there was no significant difference in terms of electrolyte levels between last day of hunger strike and 2 months after hunger strike.
Conclusion
For the first time long-term starvation is found to be associated with ER.
