Intoxication induced comatose states and the risk of malignant arrhytmia

Comatose patients, 27 intoxicated, 30 with stroke (cerebrovascular accident) and 30 control were analyzed for Q-T interval (Q-Tc) using Bazett's formula. Relative risk of prolonged Q-Tc was calculated for each group. Q-Tc was prolonged in 56.6% of intoxicated patients, in 53.3% of patients with stroke and in 6.7% of controls. The relative risk of prolonged Q-Tc for intoxicated patients was 17.5 while for patients with stroke it was 16.0. There was very little difference between the two groups: 0.9. The highest values of Q-T dispersion were seen in intoxicated patients: 88.9 +/- 51.8 ms, as compared to patients with stroke: 75.6 +/- 43.0 ms, and controls: 31.4 +/- 10.0 ms. There was no correlation between Q-Tc and serum potassium level, serum magnesium or calcium level, or metabolic acidosis.
