Some causes of bigeminal rhythm * Alternate beats are premature: atrial, ventricular, junctional * Nonconducted atrial premature beats after every second QRS * Sinus rhythm with 3:2 atrioventricular block: Wenckebach, Mobitz II * Other supraventricular rhythms with 3:2 atrioventricular block * Atrial flutter with alternating 2:1 and 4:1 block * 3:2 exit block: sinoatrial; escape rhythms--atrial, junctional, ventricular; accelerated rhythms--atrial, junctional, ventricular * Escape-capture bigeminy with escape focus: atrial, junctional, ventricular, electronic pacemaker * Atrial tachyarrhythmias with 3:2 atrioventricular response of an electronic pacemaker
