Etiology/cause
In one cohort study, causes were identified in 84%:[1]
- Cardiac arrhythmia in 43%
- Psychiatric, usually an anxiety disorder, in 31%
- Miscellaneous in 10%
Evaluation
Medical history taking
Helpful findings in one cohort study were:[1]
- Duration more than 5 minutes suggested cardiac arrhythmia
- Description of irregular heart rate suggested cardiac arrhythmia
- More than 5 total symptoms suggested noncardiac causes in the univariate analysis. A similar observation (two or more prodromal symptoms) has been observed for determining the cause of syncope[2] and psychiatric diagnoses[3].
Palpitations followed by syncope suggest cardiac arrhythmia.[4]
Physical examination
A heart rate < 60 or > 100 beats per minutes suggests cardiac arrhythmia.[5]
