Escape-Capture Quadrigeminy
Report:
Sinus rhythm
First degree AV block (PR 0.28â)
Incomplete right bundle branch block
(Slightly) accelerated ventricular (fascicular) rhythm 69 - 72/min
Sinus capture beats
Comment:
The PR interval would probably be shorter without the interfering ventricular rhythm.
The escape-capture designation is somewhat strained in this case - the escape is somewhat accelerated and the âcausalâ effective bradycardia of the capturing sinus rhythm is not very slow at 56/min. Nevertheless, the situation has some analogy to escape-capture bigeminy and coining fancy names is a temptation in oneâs old age.
A psychoanalyst would have probably called this allorhythmia repetition compulsion.
