Key result
Among patients with premature contractions, 39% perceived the contractions during a 5-minute period, and the perception rate significantly decreased as the frequency of premature contractions increased.
Why the study?
What is the perception rate of premature contractions and how does it relate to the frequency of arrhythmias and autonomic nervous system function?
Observational (n=97)
What is the perception rate of premature contractions and how does it relate to the frequency of arrhythmias and autonomic nervous system function?
Only 39% of patients perceive their premature contractions, and the perception rate paradoxically decreases as the frequency of premature contractions increases, suggesting autonomic habituation.
Symptoms may underreport frequent premature contractions; leaves open autonomic habituation mechanisms for prospective study.

Takayanagi et al. (1993) conducted an observational in Premature contractions (n=97). Self-monitoring of premature contractions using a push-button switch was evaluated on Proportion of patients who perceived premature contractions during a 5-minute period. Among patients with premature contractions, 39% perceived the contractions during a 5-minute period, and the perception rate significantly decreased as the frequency of premature contractions increased.
