ABSTRACT
Objective: To study the clinical and electrocardiographic changes in patients with seizure disorder and to find the relationship between seizure disorder and electrocardiographic abnormality, if any.
Methods: We analyzed 206 patients with seizures in whom pre-ictal electrocardiogram was available for comparison with post-ictal electrocardiogram. Arrhythmias, repolarization abnormalities, and PR and QTc intervals were determined for pre-ictal and post-ictal periods.
Results: The most common abnormality was sinus tachycardia (heart rate>100bpm) which was present in 160 patients (77.7%) followed by sinus arrhythmia in 19 patients (9.2%). CHB and bifascicular block remained in 9 patients each. APD’s were present in 18 patients (8.7%), VPD’s in 6 patients (2.9%). RBBB was present in 11 patients (5.3%), LBBB in 8 patients (3.9%), AF in 5 patients (2.4%), PSVT and T wave inversion in 1 patient each. ST segment elevation of 2mm was seen in 3 patients (1.5%) and ST segment depression in 4 patients (1.9%). The mean heart rate was 96.6 seconds and mean QTc interval was 396.4 seconds.
Conclusion: Cardiac rhythm and conduction abnormalities are common during seizures particularly if they are generalized and these abnormalities may contribute to SUDEP.
Key words: ECG in seizure disorder, SUDEP, conduction abnormality.
