Bysystole

Bisystole (Greek: “double heartbeats”) is a rare and prognostically unfavorable condition when the interval between two heartbeats is equal to or close to the systole-diastolic interval (which distinguishes the heartbeat from sinus bradycardia), which is observed with first-degree atrioventricular block. The concept means the impossibility or difficulty of conducting an impulse between the atria and ventricles of the heart, either due to the absence of a pacemaker (atrioventricular block of the second degree) or due to a conduction disorder (atrioventricular block of the third degree). With this pathology, in two consecutive sinus contractions or between them, there is a bifurcation of the cardiac cycle (50-88%): the first contraction is considered normal; the second consists of two unequal halves (this is indicated by the second “lapsus-contraction”), separated by an interval,

Bisystole or exemplary bisystole in medical practice is a concept that is associated with heart rhythm disturbances. The bisystolic state of a person is manifested by chaotic contractions of the heart. In this case, the organ freezes for two seconds or more, and then it begins to function again, but does not beat regularly
