χ
2 comparing ECG of seropositive and seronegative groups (P = 0.002) , and ‡ age (P = 0.0001) were significant. AF = Atrial fibrillation; LBBB = Left bundle branch block; LBBHB = Left bundle branch hemiblock; RBBHB = Right bundle branch hemiblock; RBBB = Right bundle branch block; ST = Sinus tachycardia.
