Electrocardiographic changes in tetanus

Fifteen patients with tetanus were included in this study. Electrocardiographic changes during tetanic sedation and after clinical cure were recorded. The most frequent ECG changes were T wave changes [80%], sinus tachycardia [73.3%], P wave abnormalities [26.6%], right sided dominance [20%], ST depression [13.3%] and sinoatrial block [one case]. Most of these abnormalities were transient and all of them disappeared nearly completely after clinical cure
