A junctional rhythm occurs when the electrical activation of the heart originates near or within the atrioventricular node, rather than from the sinoatrial node. Because the normal ventricular ...

Two patients (one in each group) had junctional rhythms. One in the HYPO group had occasional premature junctional depolarizations. The other one (NORMO group) had an accelerated junctional rhythm ...

The most frequent arrhythmias were isolated premature atrial contractions ... one patient had a persistent accelerated junctional rhythm associated with prolonged hypotension.
