fibrillations
Irregular heartbeat episodes
Fibrillations are rapid, irregular contractions of muscle fibers, especially in the heart.
Atrial fibrillation and ventricular fibrillation are potentially dangerous cardiac arrhythmias where the heart quivers chaotically rather than pumping effectively.
The term extends figuratively to any trembling or quivering: fibrillations of anxiety ran through her.
